SAFETY INFORMATION

RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION, AND

OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTS

Before Using Your Portable Two-Way Radio, Read

This Important RF Energy Awareness And Control

Information And Operational Instructions To

Ensure Compliance With The FCC’s RF Exposure

Guidelines.

NOTICE: This radio is intended for use in occupa-

tional/controlled conditions where users have full

knowledge of their exposure and can exercise control

over their exposure to meet FCC limits. This radio

device is NOT authorized for general population,

consumer, or any other use.

This two-way radio uses electromagnetic energy

in the radio frequency (RF) spectrum to provide

communications between two or more users over a

distance. It uses radio frequency (RF) energy or radio

waves to send and receive calls. RF energy is one form

of electromagnetic energy. Other forms include, but

are not limited to, electric power, sunlight and x-rays.

RF energy, however, should not be confused with

these other forms of electromagnetic energy, which

when used improperly can cause biological damage.

Very high levels of x-rays, for example, can damage

tissues and genetic material.

Experts in science, engineering, medicine, health

and industry work with organizations to develop stan-

dards for exposure to RF energy. These standards

provide recommended levels of RF exposure for both

workers and the general public. These recommended

RF exposure levels include substantial margins of

protection. All two-way radios marketed in North

America are designed, manufactured and tested to

ensure they meet government established RF expo-

sure levels. In addition, manufacturers also recom-

mend specific operating instructions to users of two-

way radios. These instructions are important because

they inform users about RF energy exposure and

provide simple procedures on how to control it. Please

refer to the following web sites for more information

on what RF energy exposure is and how to control

your exposure to assure compliance with established

RF exposure limits.

tion/index.html

FEDERAL COMMUNICATIONS COMMISSION

REGULATIONS

The FCC rules require manufacturers to comply

with the FCC RF energy exposure limits for portable

two-way radios before they can be marketed in the U.S.

When two-way radios are used as a consequence of

employment, the FCC requires users to be fully aware of

and able to control their exposure to meet occupational

requirements. Exposure awareness can be facilitated by

the use of a product label directing users to specific user

awareness information. Your EFJohnson two-way radio

has a RF exposure product label. Also, your EFJohnson

user manual, or product manual, or separate safety

booklet includes information and operating instructions

required to control your RF exposure and to satisfy

compliance requirements.

COMPLIANCE WITH RF EXPOSURE

STANDARDS

Your EFJohnson two-way radio is designed and

tested to comply with a number of national and interna-

tional standards and guidelines (listed below) for human

exposure to radio frequency electromagnetic energy. This

radio complies with the IEEE and ICNIRP exposure

limits for occupational/controlled RF exposure environ-

ment at operating duty factors of up to 50% transmitting

and is authorized by the FCC for occupational use only.

In terms of measuring RF energy for compliance with the

FCC exposure guidelines, your radio radiates measurable

RF energy only while it is transmitting (during talking),

not when it is receiving (listening) or in standby mode.

NOTE: The approved batteries supplied with this radio

are rated for a 5-5-90 duty factor (5% talk-5% listen -

90% standby), even though this radio complies with the

FCC occupational RF exposure limits and may operate

at duty factors of up to 50% talk.

Your EFJohnson two-way radio complies with the

following RF energy exposure standards and guidelines:

•United States Federal Communications Commission,

Code of Federal Regulations; 47 CFR §§ 1.1307,

1.1310, 2.1091 and 2.1093

•American National Standards Institute (ANSI) / Insti-

tute of Electrical and Electronic Engineers (IEEE)

C95. 1-1992

SAFETY INFORMATION

•Institute of Electrical and Electronic Engineers (IEEE)

C95.1-1999 Edition

RF EXPOSURE COMPLIANCE AND CONTROL

GUIDELINES AND OPERATING INSTRUCTIONS

To control your exposure and ensure compliance

with the occupational/controlled environment exposure

limits, always adhere to the following procedures.

Guidelines:

•Do not remove the RF Exposure Label from the

device.

•User awareness instructions should accompany the

device when it is transferred to other users.

•Do not use this device if the operational requirements

described herein are not met.

Operating Instructions:

•Transmit no more than the rated duty factor of 50% of

the time. To transmit (talk), push the Push-To-Talk

(PTT) button. To receive calls, release the PTT button.

Transmitting 50% of the time, or less, is important

because this radio generates measurable RF energy

exposure only when transmitting (in terms of

measuring for standards compliance).

•Hold the radio in a vertical position in front of face

with the microphone (and the other parts of the radio,

including the antenna) at least one inch (2.5 cm) away

from the nose. Keeping the radio at the proper distance

is important because RF exposures decrease with

distance from the antenna. The antenna should be kept

away from eyes.

•When worn on the body, always place the radio in an

EFJohnson approved clip, holder, holster, case, or

body harness for this product. Using approved body-

worn accessories is important because the use of

EFJohnson or other manufacturer’s non-approved

accessories may result in exposure levels which

exceed the FCC’s occupational/controlled environ-

ment RF exposure limits.

•If you are not using a body-worn accessory and are not

using the radio in the intended use position in front of

the face, then ensure the antenna and the radio are kept

at least one inch (2.5 cm) from the body when trans-

mitting. Keeping the radio at the proper distance is

important because RF exposures decrease with

increasing distance from the antenna.

•Use only EFJohnson approved supplied or replace-

ment antennas, batteries, and accessories. Use of non-

EFJohnson approved antennas, batteries, and accesso-

ries may exceed the FCC RF exposure guidelines.

•For a list of EFJohnson approved accessories, see the

service manual or marketing accessory lists or contact

GENERAL OPERATION

SECTION 3 GENERAL OPERATION

3.1 TURNING POWER ON AND SETTING

VOLUME

3.1.1 POWER UP

Power is turned on and off by the top panel On-

Off/Volume switch. When power is initially turned on,

the following events occur:

•The software version number is displayed.

•A self test is performed.

•The currently selected zone is displayed.

•If a conventional P25 channel is selected, the

Individual ID of the radio is displayed.

•If a SMARTNET/SmartZone or P25 Trunked

channel is selected, the Unit ID of the radio is

displayed.

•A tone sounds (if tones are enabled)

•The selected channel alias is displayed continuously

when power-up is complete.

Programming determines if the radio powers up

on the last selected zone or the pre-programmed home

zone. Refer to Section 3.3 for information on the

channel that is selected. The minimum volume level

may be set by programming. This can prevent missed

messages resulting from inadvertently turning the

volume to an inaudible level.

3.1.2 STANDARD AND SOFT POWER DOWN

To turn power off, rotate the On-Off/Volume

control counterclockwise until a click occurs. Power

may remain on for an instant after turn-off occurs.

A soft power down feature can be programmed to

prevent radio power from being turned off by acciden-

tally turning the on-off/volume control. Any side

button can be programmed for this function in addition

to its normal function. Then for power to turn off, this

button must be pressed during or after power is turned

off in the normal manner using the knob (there is no

time out).

3.1.3 SETTING VOLUME LEVEL

The volume level is adjusted by the top panel

volume control knob or by option buttons programmed

for the Up/Down volume function. When the buttons

are used, the volume control function of the knob is

disabled (it is still used to switch power). Volume

buttons may be used instead of the knob, for example,

if accidental turning of the volume knob is a problem.

When the volume control buttons are used, the

number of steps (ticks) required to change the volume

from the minimum level to maximum level is

programmable for 1-50. For example, if “20” is

programmed, there are 20 adjustment steps from

minimum to maximum volume. Only one volume

control button can be programmed if desired and

wrap-around then occurs after the maximum or

minimum level is selected.

The radio can also be programmed so that volume

control is also be disabled by the Keypad Lock feature.

Refer to Section 3.6 for more information.

The relative volume level can be determined by

the position of the index on the volume knob or by a

reference signal as follows:

•If a key press tone is enabled, a short tone sounds

when a key is pressed.

•If a conventional channel is selected and the

Monitor option switch or menu parameter is

programmed, pressing that switch unsquelches the

receiver and either voice or background noise is

heard (see Section 5.3). If a SMARTNET/Smart-

Zone or P25 Trunked channel is selected, the

receiver cannot be manually unsquelched.

3.2 POWER-UP PASSWORD

3.2.1 GENERAL

The power-up password feature prevents unau-

thorized use of the radio by locking the keypad on

power up until the proper password is entered. This

feature is enabled or disabled by programming.

When it is enabled, “ENTER PSWD” is briefly

displayed when power is turned on. The eight-digit

GENERAL OPERATION

numeric password must be then be entered as follows.

If an incorrect password is entered, “INCORRECT” is

displayed and it must be re-entered.

DTMF Keypad Models - Enter the password using

the 1-8 keys and then press the Enter (F2) key when

finished. If a mistake is made, the last digit can be

erased by pressing the F1 (Clear) key.

Limited Keypad Models - Select the proper number

for each position by pressing the Up/Down switch.

When the proper number for a position is displayed,

select it and move on to the next position by pressing

the F2 (Enter) key. If the password is less than eight

digits, press F2 twice after the last digit.

3.2.2 PASSWORD FEATURES

An enhanced password scheme allows up to four

power-on (user) passwords, download and upload

passwords, and a master password to be programmed.

The current User password can be changed if the

“Set User Password” option switch or menu param-

eter is programmed. Selecting this function displays

prompts for entering and confirming a new password.

It is recommended that a number key not be used for

this function because the password mode is exited if

that key is pressed to enter a number. Refer to Section

9 for more information on passwords.

3.3 ZONE AND CHANNEL SELECT

The selected zone and channel are selected and

displayed as follows. For more information on zones

and channels, refer to Section 3.9.5.

Zone Select

The front panel Up/Down switch briefly displays

and changes the alias of the current zone. When not in

special modes such as the menu mode, pressing either

the top or bottom part of this switch once displays the

alias of the current zone. Then quickly pressing it

again changes the selected zone up or down. The

rotary A/B/C switch on the top panel can also be

programmed for zone select. The “A” position then

selects Zone 1, “B” Zone 2, and “C” Zone 3 (if appli-

cable).

After the highest programmed zone is displayed,

wrap-around to the lowest programmed zone occurs

and vice versa. The selected zone is also displayed

briefly on power up. If the selected zone alias needs to

be displayed continuously, it must be programmed as

part of the channel alias.

Channel Select

Channels are selected by the rotary 16-position

switch on the top panel. The alias (identification) for

the selected channel/group is displayed continuously

during normal operation.

When an unprogrammed channel is selected,

“UNPROGRAMD” is displayed and a tone sounds (if

tones are enabled). When conventional channels are

selected and the Display Information option key or

menu parameter is programmed, either the channel

frequency or alias can be displayed (see Section 5.9).

The channel selector knob can also be disabled by

programming. Channels must then be directly selected

as described next (if applicable). It may be desirable to

disable the channel select knob when direct selection

is used in order to prevent confusion since the channel

knob then may not indicate the selected channel.

The radio can also be programmed so that the

channel select control is also be disabled by the

Keypad Lock feature (Section 3.6) similar to the

volume control described in Section 3.1.3.

Direct Zone/Channel Selection

The direct Channel Select feature is available if

the Channel Select option switch or menu parameter is

programmed. This feature allows channels to be

directly selected using the DTMF keypad numeric

keys (DTMF models only) or Up/Down switch (all

models).

For direct selection purposes, channels are

numbered sequentially starting with the lowest zone.

Each zone can be programmed with up to 16 channels,

so Zone 1 channels are numbered 1-16, Zone 2 chan-

nels 17-32, and so on as shown below. For example,

Zone 1/Channel 16 is selected by Channel 16, and

Zone 2/Channel 16 is selected by Channel 32.

GENERAL OPERATION

Proceed as follows to select channels using this

mode:

1. Enable the direct Channel Select mode by pressing

the Channel Select option switch or selecting the

“Chan Selct” menu parameter. The alias and

sequential number of the current channel are

alternately displayed.

2. Select the desired channel using the Up/Down keys

or directly enter it using the 0-9 keys (if available).

If using the 0-9 keys, the radio attempts to display

the entered number after the 3rd digit is entered or

approximately 2 seconds after the last key is

pressed.

3. To exit the this mode and select the entered channel,

press the Channel Select switch again or the F2 key.

To exit without changing the channel, press the F1

key. This mode is also exited automatically without

changing the channel after approximately 1 minute

of no activity.

NOTE: The Channel Select function should probably

not be assigned to a number key because pressing that

key to select a channel then exits the select mode.

Other features of this mode are as follows:

•When using the Up/Down keys, wrap-around to the

lowest zone/channel occurs after the last channel in

the highest programmed zone is displayed and vice

versa. For example, if Zone 1/Channel 5 is the

highest programmed channel, wrap-around occurs

after Zone 1/Channel 16 is displayed.

•When an unprogrammed channel is displayed, the

sequential channel number and “Unprogramd” are

alternately displayed.

•If an invalid channel number is entered using the

0-9 keys, or the F2 or Channel Select option switch

is pressed with “Unprogrammed” displayed, an

error tones sounds, “Invalid” is briefly displayed,

and the displayed channel does not change.

•The rotary Channel Select switch may not correctly

indicate the selected channel after direct channel

selection is used. However, if this switch is enabled

and rotated, it selects the channel it is indicating. For

example, if the switch index is pointing to channel 3

and channel 15 of the current zone is being

displayed, rotating it to channel 4 selects channel 4

of the current zone.

•If the rotary Channel Select switch is enabled, the

radio always powers up on the channel it is

selecting.

If it is disabled, the radio can be programmed to

power-up on the last selected or home channel

number of the last selected or home zone. With the

“Last Zone”/“Home Channel” configuration, the

programmed home channel number of the last active

zone is selected. If it is not programmed, “Unpro-

grammd” is displayed. With earlier models, the last

selected channel is displayed when powering up on

the last selected zone, and channel 1 is displayed

when powering up on the home zone.

3.4 LOW BATTERY INDICATION

3.4.1 GENERAL

NOTE: If the radio contains encryption keys and is not

programmed for infinite key retention, be sure to reat-

tach a battery within approximately 30 seconds to

prevent the loss of these keys (see following).

A low-battery condition is indicated by the

icon in the display. The battery should be recharged or

replaced as soon after this indication appears. Once

this indication appears, it stays on until power is

cycled.

Seq. Ch. No. Zone Channel

111

16 16

17 2 1

32 16

33 3 1

GENERAL OPERATION

The following additional low battery indications

and conditions may be enabled by programming:

•A chirp sounds once a minute in the receive standby

and transmit modes.

•A chirp sounds each time the PTT switch is pressed.

•The top panel LED indicator flashes red every 30

seconds in the receive mode.

•Low power is selected when transmitting.

As indicated in the preceding note, the radio may

need to be connected to a constant power source to

preserve the encryption keys in memory. This is

required if “infinite key retention” is not programmed.

To allow the battery to be changed without losing the

keys with this feature disabled, storage capacitors

maintain the supply voltage to memory for approxi-

mately 30 seconds without a battery attached. There-

fore, be sure to reattach a battery within that time. Refer

to Section 8.1.6 for more information on encryption

keys.

There is a battery saver feature that can be

enabled by programming. This feature functions on

trunked channels only, and it automatically selects low

transmit power when the receive signal strength

(RSSI) indicates that the site is nearby.

3.4.2 BATTERY CHARGING

NOTE: When a battery is charged while attached to

the radio, make sure radio power is off (see following).

The battery can be charged separately or while

attached to the radio. When it is charged while

attached to the radio, radio power should be turned off.

If it is not, the battery begins slowly discharging when

the charger enters the trickle charge mode. This mode

is indicated by a green Ready indication, and it is

entered automatically when the battery is nearly fully

charged. Gradual discharging occurs in the trickle

mode because the charge current of approximately 50

mA is less than the radio standby current of approxi-

mately 200 mA.

CAUTION: Do not transmit in close proximity to the

charger base (see following).

Do not expose the charger base to high level RF

signals while a battery is being charged because this

may cause a charger fuse to blow (especially in the

UHF range). Radios programmed for SMARTNET/

SmartZone operation, for example, may affiliate while

in the charger which causes them to automatically key.

Therefore, do not leave radio power on while charging

as described above.

3.5 BACKLIGHT

The backlight for the display and option keys can

be programmed to automatically turn on when any key

is pressed. It then automatically turns off after a

programmed delay of 0-7.5 seconds so that battery

drain is minimized. If the Backlight option switch or

menu parameter is programmed, the user can manually

turn the backlight on and off (it then stays on). If the

Surveillance mode is programmed, the backlight is

disabled (see Section 4.7). The radio can be

programmed so that the backlight turns on in the

keypad lock mode when a key is pressed (see next

section).

3.6 KEYPAD LOCK

The Keypad Lock feature temporarily disables

the front panel keys to prevent keys from being acci-

dentally pressed. This feature is available if the

Keypad Lock option switch is programmed. To lock

the keypad, simply press the Keypad Lock option

switch. Then to unlock the keypad again, press and

hold this switch until a tone sounds (approximately 1

second).

Permanent Keypad Lockout can also be

programmed. The keypad is then permanently disabled

and cannot be enabled by the user. Additional informa-

tion on this feature is as follows:

•A global “Front Keypad Lockout Only” function

can be selected by programming. The front panel

keys but not the side panel option keys are then

disabled by the preceding Keypad Lock and Perma-

nent Lock functions. If this function is not selected,

both the front and side panel keys are disabled. The

PTT switch is never disabled.

•The Channel Selector and Volume controls can be

programmed so that they are locked by the Keypad

Lock function.

•The “Channel Selector Enabled” function can be

programmed globally. If this is not selected, the

GENERAL OPERATION

channel selector is always disabled regardless of the

Permanent Lockout or Keypad Lock status. Chan-

nels can then be selected only by direct channel

select (see Section 3.3).

•The volume control is permanently disabled if a

Volume Up/Down option switch is programmed

regardless of the Permanent Lockout or Keypad

Lock status. Refer to Section 3.1.3 for more

information.

•There is the option to enable the backlight when a

key is pressed in the Keypad Lock mode. There is

also the option when programming conventional

channels to disable DTMF dialing.

3.7 SETTING SQUELCH

This radio does not have a squelch control. The

squelch level is preset during alignment. If the keypad

programming feature is available (see Section 5.18),

the squelch level can be changed by the user on each

conventional analog channel.

3.8 TRANSMIT DISABLE

Transmitting can be disabled on each conven-

tional, SMARTNET, SmartZone, and P25 Trunked

channel so that the channel is monitor-only. When

transmitting is attempted on a receive-only channel,

“Rx Only” is displayed and an error tone sounds.

3.9 RADIO OPERATING MODES

3.9.1 GENERAL

Each selectable channel can be programmed for

the conventional (analog or APCO Project 25 digital),

SMARTNET/SmartZone, or APCO Project 25 digital

trunked operating mode. For example, Zone 1/Channel

1 could be a conventional channel, Zone 1/Channel 2 a

SMARTNET channel, and so on. More information on

these modes follows.

3.9.2 CONVENTIONAL MODE

This is a non-trunked operating mode which

accesses independent radio channels. There is no auto-

matic access to several channels. Selecting a conven-

tional channel selects a transmit and receive frequency

and other channel parameters such as squelch control

coding.

Conventional channels can be either standard

(analog) or Project 25 (digital). With digital operation,

the DSP (Digital Signal Processor) converts the audio

signal to digital data which is sent over the air as

complex tones. Another difference is that analog chan-

nels use Call Guard (CTCSS/DCS) squelch control

and Project 25 channels use a NAC (Network Access

Code) and talk group ID codes.

With Project 25 operation, a NAC is transmitted

and it must match the NAC programmed in the base

equipment and the radio(s) being called for communi-

cation to occur. In addition, to receive standard group

calls, the receiving radio must be programmed to detect

the transmitted talk group ID code.

With conventional operation, a busy channel

condition is detected automatically if the busy channel

lockout (transmit disable on busy) feature is

programmed. Otherwise, it must be detected manually.

An out-of-range condition is not indicated by special

tones or messages as with SMARTNET operation

because there is no initial data exchange with the

repeater that allows this condition to be detected.

Operating features unique to conventional channels

are described in Section 5.

3.9.3 SMARTNET/SMARTZONE MODE

This is a trunked operating mode in which auto-

matic access is provided to several RF channels. ID

codes are used to select what radios are being called

and what calls are received. Monitoring is performed

automatically and special messages and tones indicate

busy and out-of-range conditions.

SMARTNET and SmartZone operation and

programming is very similar. Basically, SMARTNET

operation is limited to a single repeater site and Smart-

Zone operation allows automatic roaming between

sites. Enhanced SMARTNET/SmartZone features

include roaming (SmartZone only), telephone, private,

and emergency calls, Call Alert™, and messaging.

Either analog or digital signaling may be used (digital

is optional).

GENERAL OPERATION

When a SMARTNET or SmartZone channel is

selected or the radio is powered up on one of those

channels, it searches for a control channel. Once a

control channel is found, the alias (name) of the

selected channel is displayed and the radio attempts to

not be found (because of an out of range condition or

the system ID is not correct, for example), “NO SYS”

(early units) or “Out Rnge” (later units) is displayed

and the radio continues to search for a control channel.

The control channel transmits and receives

system information to and from all radios registered on

the system. Therefore, once a control channel is found,

it is continuously monitored for incoming call infor-

mation and is used to make call requests. The radio

automatically changes to a traffic channel to place and

receive calls and then returns to the control channel

when the call is complete. Operating features unique

to SMARTNET/SmartZone channels are described in

Section 6.

3.9.4 P25 TRUNKED MODE

The P25 Trunked operating features are very

similar to the SmartZone type just described. Since

SmartZone features are also similar to SMARTNET

features, all three modes are described in the

Section 6. Some differences between the P25 Trunking

and SmartZone modes are as follows:

•Digital signaling is always used with P25 calls.

Either analog or digital signaling may be used for

SmartZone calls.

•Calls made to a specific radio in the P25 mode are

called Unit Calls. In the SMARTNET/SmartZone

mode they are called Private Calls.

•Messaging is not available with P25 calls.

•The P25 control channel data rate is 9600 baud and

the digital voice data rate is also 9600 baud. With

SmartZone operation, the control channel data rate

is 3600 baud (both digital and analog calls) and the

narrowband digital voice data rate is 9600 baud.

•The P25 mode uses a system ID, Wide Area

Communications Network (WACN) ID, and RF

Subsystem ID (RFSS). The SmartZone mode does

not use the WACN and RFSS IDs.

•P25 Unit IDs can be 1-16,777,215 (000001-FFFFFF

hex) and SmartZone Unit IDs can be 1-65,535

(0001-FFFF hex).

3.9.5 SYSTEMS, CHANNELS, AND ZONES

A zone and channel are selected to place and

receive calls. The following describes the relationship

between systems, channels, and zones.

Systems

A system is a collection of channels or talk

groups belonging to the same repeater site. It defines

all the parameters and protocol information required to

access a site. Up to 16 systems of any type can be

programmed.

The maximum number of channels assignable to

a system is limited to 512. Channels may also be

limited by available memory space as described in the

following information.

Channels

A channel selects a radio (RF) channel or talk

group as follows:

Conventional Analog Mode - A channel selects a

specific radio channel, Call Guard (CTCSS/DCS)

squelch coding, and other parameters unique to that

channel.

Conventional Project 25 Mode - A channel selects a

specific radio channel, NAC squelch coding, talk

group ID, and other parameters unique to that channel.

SMARTNET/SmartZone and Trunked Project 25

Modes - A channel selects a specific talk group,

announcement group, emergency group, and other

parameters unique to that talk group.

A maximum of up to 512 channels can be

programmed with the preceding modes. These chan-

nels can belong to a single system or multiple systems.

GENERAL OPERATION

The maximum number is also limited by the available

memory. For example, since more memory is required

to program a SMARTNET system than a conventional

system, the total number of channels decreases as the

number of SMARTNET channels increases. The

programming software displays a bar graph which

shows the amount of available memory space that is

used by the current data.

Zones

A zone is a collection of up to 16 channels of any

type. For example, a zone could include 12 conven-

tional channels and 4 SMARTNET channels. One use

of zones may be to program the channels used for

operation in a different geographical areas. The

maximum number of zones is 32.

RADIO-WIDE FEATURES

SECTION 4 RADIO-WIDE FEATURES

4.1 OPTION SWITCHES

NOTE: For descriptions of the functions controlled by

these switches, refer to the section of this manual

referenced in the last column of Table 4-1.

Almost all the buttons on this radio are

programmable as follows:

•On the side panel, the three buttons above the PTT

switch (see Figure 2-3 on page 11).

•On the top panel, the rotary three-position switch

and the orange button (see Figure 2-2 on page 11).

•On the front panel, F1 and F2 unless the menu mode

is used (see next section), and F3 and F4.

•With DTMF keypad models, all 12 DTMF keys.

The functions that can be controlled by option

switches are shown in Table 4-1. Each option switch

can be programmed to control a different function in

each of the three operating modes. For example, F3

can control one function when a conventional channel

is selected, another when a SMARTNET/SmartZone

channel is selected, and still another when a Project 25

trunked channel is selected.

4.2 MENU MODE

NOTE: For descriptions of the functions controlled by

the menu mode parameters, refer to the section of this

manual referenced in the last column of Table 4-1.

Most functions that can be controlled by an

option switch can also be controlled by the menu

mode. The functions that can be controlled by the

menu mode are shown in Table 4-1. Functions can be

controlled by both an option switch and a menu

parameter if desired.

When the menu mode is used, the F1 and F2

switches become dedicated menu mode control

switches (see following illustration). The F1 switch is

Back/Clear, and the F2 switch is Menu Select/Enter. If

the menu mode is disabled, these switches can be

programmed for other functions.

Menu Mode Buttons

Only the enabled menu items which apply to the

selected channel type are displayed. For example, if a

conventional channel is selected, only the enabled

functions for conventional channels are displayed.

When in the menu mode, messages continue to be

received on the selected channel. However, the display

does not indicate who is calling. Pressing the PTT

switch exits the menu mode and keys the transmitter.

The menu mode operates as follows:

1. To select the menu mode, press the F2 key. Up to

three menu parameters are then displayed as shown

in the preceding illustration.

2. To scroll up or down through the menu parameter

list, press the Up/Down switch. The selected

parameter is indicated by a dark bar.

3. To display the available modes for a highlighted

parameter, press the F2 switch. The currently

selected mode is indicated by an asterisk.

4. Press the Up/Down switch to highlight the desired

mode. Then press the F2 key to select that mode.

5. To step back to the previous level or exit the menu

mode, press the F1 (Back) key.

4.3 TIME-OUT TIMER

The time-out timer disables the transmitter if it is

keyed continuously for longer than the programmed

time. It can be programmed for 15 seconds to 3

minutes, 45 seconds or it can be disabled.

If the transmitter is keyed for longer than the

programmed time, the transmitter is disabled, a contin-

uous tone sounds, and “TX TIMEOUT” is displayed.

Five seconds before time-out occurs, a warning beep

sounds to indicate that time-out is approaching. The

timer and tone are reset by releasing the PTT switch.

A different time can be programmed for each

system, and the timer can be enabled or disabled on

each conventional channel. With conventional chan-

nels, a penalty time may also be programmed that

prevents transmissions for a certain time after the

transmitter is disabled (see Section 5.6).

One use of this feature is to prevent a channel

from being kept busy for an extended period by an

accidentally keyed transmitter. It can also prevent

possible transmitter damage caused by transmitting for

an excessively long period.

4.4 HOME ZONE/CHANNEL SELECT

If the Home Zone option switch or menu param-

eter is programmed, it selects the preprogrammed

home zone. The selected channel is displayed if the

channel switch is enabled, and the preprogrammed

home channel is selected if it is disabled.

Pressing and holding the Home Zone option

switch until a tone sounds makes the currently selected

zone the new Home zone. The radio is also

programmed so that either the home or last selected

zone is selected when power is turned on. Refer to

Section 3.3 for more information.

4.5 POWER OUTPUT SELECT

Each conventional channel and SMARTNET/

SmartZone and P25 Trunked system can be

programmed for high, low, or switchable power. If the

High/Low Power option switch or menu parameter is

programmed and selectable power is programmed on

the current channel or system, high and low trans-

mitter power can be selected. All models support high

and low power. The low power level is typically 1 watt

and the high power level the rated power output of the

radio (2.5 - 5 watts, depending on frequency band).

The new level is flashed in the display as either

“HI POWER” or “LOW POWER”. If selectable

power is not permitted on the current channel,

“FIXED LOW” or “FIXED HIGH” is flashed and no

change occurs. The selected power level for a channel

or system is permanent until it is manually changed

again. The low power mode may be automatically

selected during a low battery condition (see

Section 3.4).

4.6 ALERT TONE SELECT

The various alert tones that sound are described

in Section 7.1. These tones can be turned on and off if

the Alert Tone option switch or Tones menu parameter

is programmed. When all tones are off, “TONE OFF”

is momentarily displayed, and when all tones are on,

“TONE ON” is momentarily displayed. If this switch

or menu parameter is not programmed, tones are fixed

in the on or off mode by programming. If the Surveil-

lance mode is programmed (see following), tones are

totally disabled.

The Alert Tone volume can be adjusted relative to

the volume control setting. This is done by program-

ming and also by the user if the Tone Volume Adjust

option button or menu parameter is programmed.

Relative levels of –170 to +170 can be set with “0” the

default setting. A minus value decreases the tone

volume and a plus value increases it. The user adjusted

level permanently overrides the programmed level if

applicable.

4.7 SURVEILLANCE MODE

The Surveillance mode totally disables the back-

light, all alert tones, and front panel LED indicator in

all operating modes. The radio can be fixed in this

mode by programming or it can be turned on and off

by the user if the Surveillance Mode option button or

menu parameter is programmed. The user selected

mode permanently overrides the programmed mode if

applicable. To provide a transmit indication when the

front panel LED is disabled, the icon is displayed

(see Section 2.4). This icon is displayed only in the

surveillance mode.

RADIO-WIDE FEATURES

4.8 SCANNING

4.8.1 INTRODUCTION

Scanning monitors the channels in the scan list

for messages that the radio is programmed to receive.

When a message is detected, scanning stops and the

message is received. Shortly after the message is

complete, scanning resumes (unless it has been

disabled). When a call is received in the scan mode,

the alias of the channel on which a call is received

(and any other display parameters that may be

programmed) are displayed until scanning resumes.

The selected channel alias is then displayed if

applicable.

There are two basic scan modes available:

Priority (Standard) and Radio Wide. The operation of

the priority type is unique to the type of channel

selected, and the operation of Radio Wide type is the

same regardless of the type of channel selected. Only

one type can be enabled at a time. For example, if

priority scanning is enabled and radio wide scanning is

selected, priority scanning is automatically disabled

and vice versa. More information on these types of

scanning follows.

4.8.2 PRIORITY SCANNING

Priority scanning (also referred to as standard

scan) monitors only channels that are the same type as

that currently selected. For example, if a conventional

channel is selected, only conventional channels are

scanned and likewise for SMARTNET/SmartZone and

Project 25 Trunked channels.

More information on how priority scanning oper-

ates in the Conventional Mode is located in Section

5.11, and for the other modes in Section 6.12. Priority

scanning is turned on and off by the Scan option

switch or menu parameter as follows. If this switch or

menu parameter is not programmed, Priority scanning

is not available.

•Enable scanning using the Scan option switch or

menu parameter. Scanning is enabled when “Scan

On” is briefly displayed and the icon is

indicated.

•To turn scanning off, press the Scan option switch

again or select “Off” in the scan menu. Scanning is

disabled when “Scan Off” is briefly displayed and

the icon is no longer indicated.

•If the zone or channel is changed while scanning is

selected, scanning continues on the same or a

different scan list (see Section 4.9.1).

NOTE: Each SMARTNET/SmartZone and P25 trunked

channel can be programmed so that scanning is auto-

matically enabled when the channel is selected.

4.8.3 RADIO WIDE SCANNING

NOTE: Use radio wide scanning only if two different

channel types need to be scanned at the same time

such as conventional and SMARTNET/SmartZone.

Otherwise, use the more efficient priority scanning

because there is less chance of missed calls.

Radio wide scanning monitors the channels in the

preprogrammed radio-wide scan list. This scan list can

include up to 16 channels of any type and assigned to

any zone (see Section 4.9.2). Radio wide scanning is

turned on and off by the Radio Wide Scan option

switch or menu parameter as follows. If this switch or

menu parameter is not programmed, radio wide scan-

ning is not available.

•Enable Radio Wide Scanning using the Radio Wide

Scan option switch or menu parameter. Radio wide

scanning is enabled when “RW Scn On” is briefly

displayed and the icon is indicated.

•To turn radio wide scanning off, press the Radio

Wide Scan option switch again or select “Off” in the

menu. Scanning is disabled when “RW Scn Off” is

briefly displayed and the icon is no longer

indicated.

•If the zone or channel is changed while radio wide

scanning, scanning continues normally.

4.8.4 SCAN HOLD TIME

When a message is received or transmitted while

scanning, there is a delay before scanning resumes.

The delay after receiving a call prevents another

message from being received before a response can be

made. The delay after transmitting a call ensures that a

response is heard instead of another message occurring

on some other channel.

RADIO-WIDE FEATURES

Separate delay times are programmable for Radio

Wide and Priority scanning. With radio wide and

conventional priority scanning, delays of 0-7.5

seconds are programmable in 0.5-second steps. With

SMARTNET/SmartZone and P25 Trunked priority

scanning, a scan delay of 2-10 seconds can be

programmed in 0.5-second steps.

4.8.5 TRANSMITTING IN THE SCAN MODE

Priority Scan Mode

When the transmitter is keyed while scanning is

enabled, the transmission may occur on various

channels as follows.

Conventional Operation - Transmissions can be

programmed to always occur on the priority,

selected, or receive channel (if applicable). Refer to

Section 5.11 for more information.

SMARTNET/SmartZone/P25 Trunked

Operation - If scanning is halted to receive a

message, programming determines if transmis-

sions occur on the selected or active channel.

Transmissions at other times occur on the selected

channel.

Radio Wide Scan Mode

The radio can be programmed to transmit on the

selected or active channel similar to SMARTNET/

SmartZone and P25 trunked operation just described.

4.8.6 NUISANCE CHANNEL ADD/DELETE

With priority scanning, channels can be tempo-

rarily deleted from the scan list, for example, if

messages become annoying. This feature is not avail-

able with radio wide scanning. Channels can also be

permanently added or deleted from a scan list as

described in the next sections. Proceed as follows to

temporarily delete a nuisance channel:

NOTE: The selected channel and also priority chan-

nels cannot be deleted from the scan list.

1. While receiving a message on the channel to be

deleted, press and hold the Scan option switch until

a tone sounds (about 1 second).

2. The channel is then deleted and scanning of the

remaining channels in the scan list resumes.

3. Deleted channels are added back into the scan list if

any of the following occur:

•Scanning is turned off and then on again using the

Scan option switch or menu parameter.

•Radio power is turned off and then on again.

•The selected channel is changed.

4.9 SCAN LISTS

4.9.1 PRIORITY SCAN LISTS

General

NOTE: The selected channel is always scanned.

A scan list is simply the channels that are scanned

when scanning is enabled. With all operating modes,

as many priority scan lists as are required can usually

be programmed (up to 256). The only limitation is the

available memory. Each scan list can include up to 512

channels/talk groups. More information on selecting

and editing priority scan lists follows.

Determining Channels in Priority Scan List

The channels in conventional priority scan lists

are indicated by selecting the scan mode as follows.

Channels in SMARTNET/SmartZone/P25 Trunked

priority scan lists are indicated only when editing a

scan list (see “Editing a Priority Scan List” which

follows).

1. Enable priority scanning using the Scan switch or

menu parameter. Also select the scan list if appli-

cable as described in the following “Selecting a

Priority Scan List” description.

2. Select the desired zone and then scroll through the

channels by rotating the channel switch. When the

displayed channel is in the scan list (scanned

normally), the icon is displayed.

RADIO-WIDE FEATURES

Selecting a Priority Scan List

NOTE: Only priority scan lists are selectable.

Conventional Channels - Conventional systems are

programmed with a default scan list that is normally

selected by all channels in that system. However, there

is a programmable option to slave a particular conven-

tional scan list to a zone. This then becomes the

default list for all conventional channels in that zone

(it overrides the system programming). This slave

feature is programmed on the Edit Zone screen.

If the Scan (List) Select option switch or menu param-

eter is programmed, the default list selected by all

conventional channels (even those belonging to slaved

zones) is temporarily changed. The preceding default

scan lists are automatically reselected whenever radio

power is cycled.

SMARTNET/SmartZone and Project 25 Trunked

Channels - Each channel (talk group) can be

programmed so that one of the programmed lists is

selected or scanning is disabled (No List). In addition,

channels can be programmed so that scanning is auto-

matically enabled (Auto Scan) when they are selected.

If the Scan (List) Select option switch or menu param-

eter is programmed, the list that is selected by all talk

and announcement groups in the current system can be

temporarily changed by the user as follows. “No List”

(scanning disabled) or “Programmed” (default list) can

also be selected if desired. The programmed default

scan list is automatically reselected on power up.

To change the currently selected scan list (all

channel types), proceed as follows:

1. With scanning disabled ( icon not displayed),

press the Scan List option switch or select the Scan

Selct menu parameter.

2. The currently selected list is displayed as “List x”,

where “x” is the currently selected list. To exit

without changing the selected list, simply press the

Scan List option switch again or the F1 key.

3. To select another list, press the Up/Down switch.

When the desired list is displayed, select it and exit

this mode by pressing the Scan List option switch

again or the F1 or F2 key.

Editing a Priority Scan List

If the Scan Edit option switch or menu parameter

is programmed, conventional, SMARTNET/

SmartZone, and P25 Trunked priority (standard) scan

lists can be user programmed. Changes are permanent

(cycling power does not reselect a default condition).

Proceed as follows:

1. Make sure that both priority and radio wide scan-

ning are off ( icon not displayed). Select a

conventional or SMARTNET/SmartZone/P25

Trunked channel corresponding to the scan list

being programmed.

2. Select the scan edit mode using the Scan Edit option

switch or menu parameter. This mode is indicated

by in the display.

3. If applicable, select the list to be edited by pressing

the Up/Down switch. Select the desired list by

pressing the F2 key. The selected list is indicated as

“LIST x”. If user programming is disabled on a list,

(conventional only) “NO EDIT” is momentarily

displayed and it cannot be edited.

4. Select the channel you want to add or delete by

pressing the Up/Down switch. After the last channel

in the current zone is displayed, the first valid

channel in the next zone is displayed and vice versa.

Lists are limited to 512. If an attempt is made to add

more than 512, “LIST FULL” is displayed and a

channel must be deleted before another can be

added.

NOTE: Priority channels can be deleted.

5. If the selected channel is in the scan list (scanned),

the icon is displayed. To change the status of

the displayed channel, press the F2 (Enter) switch.

With conventional channels only, if the selected

scan list is programmed with fixed priority

channel(s), the next press of F2 makes the current

channel the priority channel indicated by . If

dual priority channels are used, pressing F2 again

makes it the second priority channel indicated by

RADIO-WIDE FEATURES

. Then pressing F2 again takes the channel out

of the scan list. Refer to Sections 5.11.3 and 6.12.2

for more information on priority channel sampling.

6. To exit this mode and save the changes, press the F1

(Exit) key or the Scan Edit option switch again.

4.9.2 RADIO WIDE SCAN LISTS

General

With radio wide scanning, there is only one scan

list available regardless of the type of channel selected.

This list is user programmable in later units, and can

contain up to 16 channels of any type. For example, it

could include six conventional channels and ten

SMARTNET/SmartZone channels. More information

on selecting and editing radio wide scan lists follows.

Determining Channels in Radio Wide Scan List

The channels in radio wide scan lists are deter-

mined by selecting the scan list edit mode (see

“Editing Radio Wide Scan List” which follows).

When the displayed channel is in the radio wide

scan list (scanned normally), the icon is

displayed.

Editing a Radio Wide Scan List

If the RWS Edit option switch or menu param-

eter is programmed, the radio wide scan list can be

edited. Changes are permanent (cycling power does

not reselect a default condition). Proceed as follows:

1. Make sure that both priority and radio wide scan-

ning are off ( icon not displayed). Select the

scan edit mode using the RWS Edit option switch or

menu parameter. This mode is indicated by in

the display.

2. Select the channel you want to add or delete by

pressing the Up/Down switch. After the last channel

in the current zone is displayed, the first valid

channel in the next zone is displayed and vice versa.

Lists are limited to 16 channels. If an attempt is

made to add more than 16, “LIST FULL” is

displayed and a channel must be deleted before

another can be added.

3. If the selected channel is in the scan list (scanned),

the icon is displayed. To change the status of

the displayed channel, press the F2 (Enter) switch.

4. To exit this mode and save the changes, press the F1

(Exit) key or the RWS Edit option switch again.

CONVENTIONAL MODE FEATURES

SECTION 5 CONVENTIONAL MODE FEATURES

5.1 INTRODUCTION

An overview of the conventional operating mode

is located in Section 3.9.2. The following information

describes the features unique to analog and digital

(Project 25) conventional operation. Refer to the

preceding “Radio Wide Features” section (4) for infor-

mation on features common to all operating modes.

5.2 MONITORING BEFORE TRANSMITTING

With conventional operation, you may need to

manually monitor the channel before transmitting to

make sure that it is not be used by someone else. If

you were to transmit while someone else was using the

channel, you would probably disrupt their conversa-

tion. With SMARTNET/SmartZone and P25 Trunked

operation, monitoring is performed automatically.

Monitor conventional channels automatically or

manually as follows:

Automatic Channel Monitoring

If the selected channel is programmed for Busy

Channel Lockout (also called Transmit Disable On

Busy), monitoring is performed automatically. Refer

to Section 5.4 for more information on this feature.

Manual Channel Monitoring

The automatic monitoring just described may

occasionally disable the transmitter when the channel

is not in use, such as if the repeater has extended hang

time. In this case, you may not want to use it and the

channel must then be monitored manually as follows:

Busy Indicator - With scanning disabled, note if the

multi-function indicator on the front panel is steady

green. If it is not, the channel is not being used and a

call can be transmitted. It it is green, a carrier is being

detected, so the channel may be busy (see following).

Monitor Mode - There may be times when a busy

condition is indicated even though no one is using the

channel. Monitoring should then be performed by

disabling Call Guard squelch (or group ID detect on

Project 25 channels). This is usually done by selecting

the Monitor Mode (see following) or by the Normal/

Selective option switch or menu parameter (see Section

5.5.5).

5.3 MONITOR MODE

The monitor mode unsquelches the receiver and

monitors the channel even if a carrier is not detected.

Other features of this mode are as follows:

•Call Guard (CTCSS/DCS) squelch is disabled on

analog channels and NAC and group ID detect are

disabled on P25 (conventional) channels.

•Busy Channel Lockout is overridden (see next

section)

•Scanning temporarily halts

The Monitor Mode operates as follows:

1. To monitor the transmit frequency for activity

before transmitting, briefly press the Monitor option

switch or select the Monitor menu “Tx Channel”

parameter. The icon is then displayed to indicate

the monitor mode and the receiver unsquelches.

2. To monitor the receive frequency instead, press and

hold the Monitor option switch until a tone sounds

or approximately 2 seconds, or select the Monitor

menu “Sqlch Ovrd” parameter. This can be used, for

example, to improve reception if intermittent

squelching is making a weak message difficult to

understand.

3. To disable the monitor mode and return to normal

operation, press the Monitor option switch again of

select the Monitor menu “Off” parameter.

The Normal/Selective function disables Call

Guard squelch and P25 group ID detect but not

scanning and P25 NAC detect (see Section 5.5.5).

5.4 BUSY CHANNEL LOCKOUT

The Busy Channel Lockout feature (also called

Transmit Disable on Busy) automatically disables the

transmitter if the channel is busy when the PTT switch

is pressed. When the transmitter is disabled by this

CONVENTIONAL MODE FEATURES

feature, “BUSY” is displayed, a busy tone sounds, and

the transmitter is disabled.

The Busy Channel Lockout feature can be

programmed to operate as follows. Each conventional

channel can be programmed differently.

Off - Busy channel lockout is disabled and the trans-

mitter keys even if the channel is busy.

Noise - If a carrier is detected on the channel, the

transmitter is disabled when the PTT switch is pressed.

Tone (NAC) - If an incorrect Call Guard (CTCSS/

DCS) or NAC code (see Section 5.17) is detected, the

transmitter is disabled when the PTT switch is pressed.

An incorrect code is any code other than the one

programmed for the current channel.

If Busy Channel Override is permitted by

programming, it is possible to transmit even when the

transmitter is disabled by this feature. Simply release

the PTT switch and then quickly press it again.

5.5 CALL GUARD SQUELCH

5.5.1 INTRODUCTION

Tone or digital Call Guard squelch (also called

CTCSS/DCS signaling) can be programmed on each

conventional analog transmit and receive channel in

any order desired. The reverse burst and turn-off code

are always transmitted and also detected on channels

programmed with Call Guard squelch.

The Call Guard squelch feature eliminates

distracting messages intended for others using the

channel. This is done by using a subaudible tone or

digital code to control the squelch. This tone or code is

unique to a user or a group on that channel. This tone

or code is transmitted with the voice signal but is not

heard because it is in the subaudible range and is atten-

uated by a filter. Call Guard squelch must be used in

both the transmitting and receiving radio to be func-

tional.

5.5.2 CALL GUARD SQUELCH ENABLE/

DISABLE

The Normal/Selective option switch or menu

parameter (if programmed) can be used to disable

receive Call Guard squelch on analog channels or

group ID code detection on P25 channels. When selec-

tive squelch is disabled, “Sq Normal” is flashed in the

display, and when it is enabled, “Sq Select” is flashed.

When “Normal” is selected, the receiver

unsquelches only if a carrier is detected. Scanning and

Project 25 NAC detection are not disabled with this

mode selected. The selected mode is in effect until it is

manually changed again. Selecting another channel or

cycling power does not reselect a default condition.

There is a programmable option to display the monitor

icon when the “Normal” mode is selected.

5.5.3 TONE CALL GUARD SQUELCH

Tone-type Call Guard squelch utilizes subaudible

CTCSS tones from 67-254.1 Hz. Although there are 42

tones assigned, those above 33 (210.7 Hz) are normally

not used because of their close proximity to the voice

band which starts at 300 Hz. In addition, tones 11 (97.4

Hz), 39 (69.3 Hz), 40 (206.5 Hz), 41 229.1 Hz), and 42

(254.1 Hz) are normally not used because they may

cause interference with adjacent tones.

A reverse burst is transmitted when the push-to-

talk switch is released and also detected when calls are

received. It is a 180-degree phase reversal for a period

of time determined by the tone frequency, and it elimi-

nates the squelch tail (noise burst) in the receiving

radio. Both the transmitting and receiving radio must

be equipped with this feature for it to be utilized.

5.5.4 DIGITAL CALL GUARD SQUELCH

Digital Call Guard squelch (DCS) uses digital

data instead of subaudible tones to control the squelch.

This data consists of continuous repetitions of 23-bit

words. No bit or word synchronization information is

used. When the push-to-talk switch is released, a turn-

off code is transmitted which eliminates the squelch

tail similar to the reverse burst.

Although there are thousands of possible code

combinations with 23 bits, only 83 are unique with the

data scheme used. The number specified when the

code is programmed is actually a seed for a special

algorithm used to generate the 23-bit data word. The

data is transmitted at a rate of 134.4 bits per second.

Therefore, approximately six words are transmitted

each second. When the data is decoded, 23-bit samples

CONVENTIONAL MODE FEATURES

are taken and then the bits are rotated to determine if a

valid code was received.

5.5.5 SELECTIVE SQUELCH CODE SELECT

(CTCSS/DCS/NAC)

NOTE: Call Guard codes can be permanently repro-

grammed by keypad programming described in

Section 5.18.

This feature allows the normal transmit and

receive Call Guard (CTCSS/DCS/NAC) program-

ming to be temporarily overridden with a code

selected from a preprogrammed list. It is available if

the Squelch Select List option switch or menu param-

eter and a CTCSS/NAC code list have been

programmed.

In addition, conventional systems can be

programmed for the Keypad CTCSS/DSC feature.

Codes can then be selected directly from the table by

pressing the key for the code. For example, to select

code 3 from the table, simply press the “3” key. No

other conventional mode functions can then be

assigned to these keys.

The CTCSS/DCS/NAC list is programmed with

up to 64 tone (CTCSS) or digital (DCS) Call Guard

codes. Different codes can be programmed for the

transmit and receive modes, and carrier squelch (selec-

tive squelch disabled) can be programmed if desired.

In addition, each position can be programmed with an

NAC code for use with P25 operation.

When the Call Guard code is changed using this

feature, it remains selected even if other channels are

selected. However, if radio power is cycled or a talk-

around channel is selected, the normal codes are rese-

lected. When scanning, the selected code also applies

to all scanned channels. Each channel can also be

programmed to always ignore the code selected from

this list and use the default code instead.

If both analog and digital (Project 25) channels

can be selected or scanned, the CTCSS/DCS code for

the selected position is used for analog channels and

the NAC code for the selected position is used for P25

channels. If a channel is programmed for mixed mode

operation, the selective squelch type (analog or digital)

programmed for the transmit mode determines the

selective squelch type used.

Proceed as follows to select a code using the

Squelch Select List option button or menu parameter:

1. Press the Squelch Select List option switch or select

the Sqlch Code menu mode parameter. Then press

the Up/Down switch to select the desired code. The

display indicates “SEL SQ xx” where, “xx” is the

selected code from 1-64. The code number and

actual code are alternately displayed (NACs are

displayed in hexadecimal).

2. To select the displayed code and return to the normal

display, press the F2 (Select) key or the Squelch

Select List switch again.

3. To check which code is selected, press the Squelch

Select List switch once to display the current selec-

tion and then again to return to normal operation.

4. To return to the normal selective squelch codes,

select “DEFAULT” in this mode. As previously

described, the normal codes are also automatically

reselected whenever radio power is cycled or a talk-

around channel is selected.

5.6 PENALTY TIMER

A penalty timer may be programmed on conven-

tional systems to prevent transmissions for the

programmed time after the time-out timer disables the

transmitter (see Section 4.3). The penalty timer can be

programmed for the same times as the time-out timer,

and timing starts when the PTT switch is released. If

the PTT switch is pressed during the penalty time, the

time-out indication occurs again and the transmitter

remains disabled. When the penalty timer expires, a

beep sounds and the transmitter can be keyed.

5.7 CONVERSATION TIMER

A conversation timer can be programmed on

conventional systems in addition to the time-out timer

(see Section 4.3). This timer limits the total length of a

conversation rather than just the length of each trans-

mission as with the time-out timer. The following is

more information on this timer.

CONVENTIONAL MODE FEATURES

•It can be programmed for times up to 7.5 minutes.

•It is reset when the time between transmissions

exceeds the time programmed for the penalty timer.

•A warning beep sounds 5 seconds before this timer

disables the transmitter.

•When this timer disables the transmitter, a contin-

uous tone sounds and the red transmit indicator

turns off. The PTT switch must then be released

until the penalty timer expires (indicated by a beep).

5.8 REPEATER TALK-AROUND

Normally, all transmissions go through a repeater

which usually increases range. However, there may be

times when a user is out of range of the repeater and

therefore unable to talk to anyone even though the user

being called is only a short distance away. To allow

communication in this situation, repeater talk-around

can be selected. Transmissions then occur on the

receive frequency which permits direct radio-to-radio

communication.

Repeater talk-around can be selected if the RTA

option switch or menu parameter is programmed.

When talk-around is enabled by this switch, is

displayed. This feature remains enabled during scan-

ning, and changing channels or turning power off does

not change the selected condition. Talk-around is

available on conventional channels only, and power

output is reduced in this mode.

5.9 DISPLAYING TRANSMIT/RECEIVE

FREQUENCY

If the Displayed Information option switch or

menu parameter is programmed (see Section 4.1), it can

be used to display the channel frequency in megahertz.

Pressing this switch toggles between displaying the

standard channel alias and the channel frequency. The

receive frequency is displayed when receiving and the

transmit frequency is displayed when transmitting. This

feature is available on conventional channels only.

5.10 EMERGENCY ALARM AND CALL

5.10.1 INTRODUCTION

Emergency Alarms and Calls are separate func-

tions that can be individually enabled or disabled on

each analog and P25 conventional system. The Emer-

gency option switch or menu parameter is required for

these functions. Emergency Alarms and Calls are

transmitted on the global (radio wide) emergency

zone/channel if one is programmed. If it is not

programmed, the emergency is transmitted on the

selected channel. The emergency programming of the

system to which that channel is linked controls the

emergency operation.

5.10.2 EMERGENCY ALARMS

An emergency alarm is a special transmission that

alerts a dispatcher of an emergency situation. It is sent

automatically by simply pressing the Emergency

option switch or selecting the Emergency menu

parameter. The system to which the emergency

channel is linked must have Emergency Alarms

enabled. If it does not, Emergency Alarms are

disabled.

In the P25 conventional mode, a special P25

emergency data transmission is sent, and in the

conventional analog mode, an DTMF emergency ID is

sent. This ID is programmed on the Conventional

Radio Wide screen. Refer to Section 5.15 for informa-

tion on MDC1200 Emergency Alert.

Proceed as follows to send an emergency alarm:

1. If required, select a channel of a system on which

Emergency Alarms are enabled and then press the

Emergency option switch or select that menu

parameter. The radio then automatically transmits

the emergency alarm.

2. Either Normal or Silent operation can be

programmed. With Normal operation, the red LED

lights, the emergency tone sounds, and

“EMERGNCY” flashes in the display. This indica-

tion continues to flash until the alarm mode is ended

(see step 4). If silent operation is programmed or the

Surveillance mode is selected (see Section 4.7),

none of these indications occur. If “No Receive

Activity During Emergency” is programmed,

receive audio, the front panel LED, and receive

icons are disabled in the receive mode.

3. When the emergency alarm is acknowledged by the

dispatcher, “ACK RCVD” is briefly displayed and

the emergency acknowledge tone (two beeps)

CONVENTIONAL MODE FEATURES

sounds. This alert tone can be disabled if desired,

and neither occur if Silent operation is programmed.

4. The emergency alarm mode is exited when radio

power is cycled or by pressing and holding the

Emergency option switch.

5.10.3 EMERGENCY CALLS

General

The Emergency Call feature allows a user to

place an emergency voice call by pressing the PTT

switch after pressing the Emergency option button or

selecting the Emergency menu parameter. If the Emer-

gency Hot Mic feature is enabled, the emergency call

is automatically transmitted without having to press

the PTT switch (see following description). The

system to which the emergency channel is linked must

have Emergency Calls enabled. Analog and Digital

(P25) calls can be individually enabled.

If the emergency call is sent on a P25 channel, an

emergency indication is sent according to the P25

standard (the emergency bit is set in the Common Air

Interface). If it is sent on an analog channel, the

DTMF Emergency ID is sent in place of the ANI

DTMF PTT ID if applicable. NOTE: The DTMF

Emergency ID is sent only if pre- or post- DTMF ANI

is enabled on the channel by programming.

Emergency Hot Mic

If Emergency Hot Mic has been enabled for

emergency calls, automatic transmitting occurs with

microphone audio unmuted without having to manu-

ally press the PTT switch. The automatic transmit

period is programmed for 10-120 seconds in 10-

second steps. If this feature or emergency calls are not

enabled by programming, automatic transmitting does

not occur. This feature is initiated only on the first

press of the Emergency switch. Subsequent presses do

not trigger automatic transmissions. To reset this func-

tion, the channel must be changed or power cycled.

Placing an Emergency Call

1. If required, select a channel of a system on which

Emergency Calls are enabled and press the Emer-

gency option switch or select that menu parameter.

The Emergency Alarm is then sent as described in

Section 5.10.2 if applicable.

2. If the preceding Emergency Hot Mic feature is

enabled, the call is automatically transmitted

without pressing the PTT switch. If it is disabled,

press the PTT switch and begin speaking as with a

standard call. If the channel is changed, operation

continues on the new channel in the emergency

mode.

3. With analog calls, subsequent presses of the PTT

switch cause the DTMF emergency ID to be sent

according to the ANI programming (if DTMF ANI

is enabled on the channel). With digital calls, the

calls continue to have the emergency bit set.

4. If the Surveillance Mode is enabled (see Section

4.7), all indicators, lights, and tones are disabled. If

“No Receive Activity During Emergency” is

programmed, receive audio, the front panel LED,

and receive icons are disabled in the receive mode.

5. To exit this mode, cycle radio power or press and

hold the Emergency switch.

5.10.4 EMERGENCY MAN-DOWN FEATURE

To have this feature, a special man-down switch

(currently available only from third-party vendors) is

attached to the accessory connector of the radio. Then

if this feature is enabled by programming and the radio

is in a horizontal position for longer than the

programmed time (0-63 seconds), an emergency

condition is triggered the same as if the Emergency

switch was pressed. The emergency can be canceled

by a press and release of the Emergency switch. Note

that accessories such as speaker-microphones cannot

be used with this feature.

5.11 CONVENTIONAL MODE SCANNING

5.11.1 GENERAL

Channel scanning features common to all oper-

ating modes are described in Sections 4.8 and 4.9. The

following information describes features unique to

conventional operation.

CONVENTIONAL MODE FEATURES

5.11.2 TRANSMITTING IN SCAN MODE

Each conventional scan list can be programmed

for one of the following modes. These modes deter-

mine if priority sampling occurs and also the channel

on which transmissions occur while scanning. Refer to

the next section for more information on priority

sampling.

No Priority - No priority channel sampling occurs

when the list is selected. The radio transmits on the

selected channel.

Priority/Tx Selected - Priority sampling occurs and

the priority channel or channels are those programmed

in the selected scan list. The radio transmits on the

selected channel.

Priority/Tx Priority (1) - Priority sampling occurs

and the priority channel or channels are those

programmed in the selected scan list. The radio

transmits on the priority (1) channel.

Priority (1) on Selected - The priority (1) channel is

always the selected channel. The radio transmits on

the selected channel.

Talkback - No priority sampling occurs. The radio

transmits on the channel of a call while scanning is

halted. Then once scanning resumes, it transmits on

the selected channel.

5.11.3 PRIORITY CHANNEL SAMPLING

NOTE: The following describes priority sampling

when scanning conventional channels. Priority

sampling when scanning SMARTNET/SmartZone/P25

Trunked channels is described in Section 6.12.

General

The priority channel sampling feature ensures

that when priority scanning, messages on the priority

channel are not missed while listening to a message on

some other channel. The radio can be programmed as

just described so that the priority channel is a fixed

channel programmed in the current scan list, the

currently selected channel, or not used.

NOTE: The priority channel is not scanned if the

active channel is an analog channel on the same

frequency as the priority channel and is programmed

with CTCSS/DCS squelch control.

Either a single or dual priority channels can be

programmed if desired. With dual priority, a call on

the second priority channel is interrupted by a call on

the first priority channel but not vice versa. When

scanning and the selected channel is a single or first

priority channel, is indicated in the display. This

indication is displayed regardless of whether the

priority channel is fixed or always the selected

channel. When it is a second priority channel, is

displayed.

The priority channel sampling frequency is deter-

mined by the programmed Priority Lookback Time A

(see description which follows). For example, if 2.0

seconds is programmed, the priority channel is

sampled every 2.0 seconds when listening to a

message on a non-priority channel. When not listening

to a message, the priority channels are scanned in the

normal scan sequence. With dual priority, the first and

second priority channels are alternately sampled at the

Lookback Time.

Priority channel sampling occurs only with

conventional priority scanning. It does not occur with

radio wide scanning, when listening to any type of

SMARTNET/SmartZone/P25 trunked call, encrypted

call, or when transmitting (see preceding note). A

series of “ticks” may be heard when the priority

channel is sampled while listening to a message on

some other conventional channel.

The priority sampling times are programmed by

the following parameters:

Lookback Time A - This time determines how often

the priority channel is checked for activity. Times of

0.25-4.00 seconds in 0.25-second steps can be

programmed.

Lookback Time B - This time determines how often

the priority channel is checked once an incorrect Call

Guard (CTCSS/DCS) or NAC code is detected. Since

it takes much longer to detect an incorrect Call Guard

signal than a carrier, this time should be relatively long

to prevent the interruptions from making a message

difficult to understand. Times of 0.5-8.0 seconds can

be programmed in 0.5-second steps.

CONVENTIONAL MODE FEATURES

Changing the Priority Channel

If a fixed priority channel is associated with the

current scan list, it can be changed if the Priority

option switch or menu parameter is programmed. With

dual priority, this function changes only the first

priority channel. To change both priority channels, use

the Scan List Edit function described in Section 4.9.1.

Proceed as follows to change the priority channel

using the Priority option switch/menu parameter:

1. Make sure scanning is disabled ( icon not

displayed) and the desired scan list is selected (see

Section 4.9).

2. Select the channel you want to be the priority

channel and then press the Priority option switch or

select that menu parameter. “Priority” is then

flashed to indicate that the current channel is now

the priority channel when scanning that list. Other

indications that may occur are as follows:

•If “No Priority” is displayed, priority sampling

may not be enabled on the scan list.

•If “Sel Chan” is displayed, the priority channel is

always the selected channel and cannot be

changed.

•If no indication displayed, the scan list may not be

user editable or the channel may not be in the scan

list.

5.12 STANDARD CONVENTIONAL CALLS

Standard conventional calls are placed to other

radio units monitoring the selected channel. The

proper coded Call Guard squelch tone or code or P25

NAC may need to be transmitted by your radio for

them to receive a call (see Sections 5.5 and 5.17.3).

Placing a Standard Conventional Call

1. Turn power on and set the volume as described in

Section 3.1. Select the channel programmed for the

radio you want to call as described in Section 3.3.

2. Monitor the channel automatically or manually as

described in Section 5.2.

3. Press the PTT switch and if the Busy Channel

Lockout feature is programmed on the channel (see

Section 5.4), the transmitter is automatically

disabled if the channel is busy. Otherwise, busy and

out-of-range conditions are not indicated.

4. Press (and hold) the PTT switch to talk and release

it to listen.

Receiving a Standard Conventional Call

1. Select or scan the channel programmed for the call

you want to receive (refer to Sections 4.8 and 4.9 for

more scanning information).

2. When the call is received, press the PTT switch to

talk and release it to listen. If scanning, responses

may occur on the priority, selected, or receive

channel as described in Section 5.11.2.

5.13 DTMF/ANI SIGNALING

DTMF (Dual Tone Multi-Frequency) tones can

be generated for ANI (Automatic Number Identifica-

tion) and other purposes on conventional analog

channels. One of the following options may be

enabled on each channel:

Pre-Tx ANI - A preprogrammed ANI sequence is

automatically sent each time the PTT switch is

pressed.

Post-Tx ANI - A preprogrammed ANI sequence is

automatically sent each time the PTT switch is

released.

When an emergency alarm or call is placed, this

ANI signaling is replaced by the Emergency DTMF

ID (see Section 5.10). Refer to Section 5.15 for

information on MDC1200 ANI.

5.14 SINGLE TONE ENCODER

This feature allows the user to transmit a single

tone by pressing the Single Tone Encoder option

switch or selecting that menu parameter. Each conven-

tional system can be programmed for a tone of 500-

2500 Hz in 1 Hz steps with a duration of 0.5-2.5

seconds in 0.1 second steps.

CONVENTIONAL MODE FEATURES

5.15 MDC1200 COMPATIBILITY

MDC1200 is a signaling protocol designed and

implemented by Motorola for analog channels only.

The following features of this protocol are supported.

Either MDC1200 or standard DTMF ANI/Emergency

signaling can be programmed on each conventional

system.

MDC1200 ANI - Both pre and post ANI are

supported.

MDC1200 Emergency Alert - A retry counter is

implemented. Currently, ACKs are not decoded so the

radio retrys the programmed number of times with

each emergency.

5.16 CLONE MODE

5.16.1 GENERAL

The Clone feature enables one radio to program

another with identical information. The PCConfigure

programming software is not required. This feature is

is not available with 53xx mobiles. Other requirements

are as follows:

•The Clone menu parameter must be enabled in the

master (sending) radio. This parameter is not

required with the slave (receiving) radio.

•The master and slave radios must be identical

models (same frequency range and options).

Only zones with conventional analog and P25

channels can be transferred using this function. Any

SMARTNET/SmartZone and P25 trunked informa-

tion is not transferred. In addition, the P25 Unit ID,

encryption keys, and the RSI ID and other OTAR

information are not transferred. Cloned zones are indi-

cated in the slave radio by an asterisk in the first char-

acter position of the zone alias (the first character is

replaced by this asterisk).

5.16.2 WIRELESS CLONING

A new wireless cloning feature is available that

allows one radio to program another using an RF link

instead of having to be physically connected by a

cloning cable. This feature is available on P25 conven-

tional channels only.

The wireless cloning feature utilizes the P25 data

functionality of the radio. Therefore, a conventional

P25 channel must be programmed in both radios and

the slave radio must have been programmed with a

P25 Unit ID. In addition, Data Registration must be

enabled in both radios. If it is not programmed,

“Disabled” is displayed. Radios with wireless cloning

capability have a new selection in the cloning menu to

select either Clone N (Normal) or Clone W (Wireless).

If Wireless is selected, an additional menu is displayed

for entering the P25 Unit ID of the destination radio

(slave). The Zone/Complete mode is then selected.

5.16.3 CLONING PROCEDURE

1. With normal (non-wireless) cloning, connect the

master (sending) radio to the slave (receiving) radio

using Cloning Cable, Part No. 023-5100-930.

2. On the master radio, select the Clone menu param-

eter and press the F2 key. If applicable, select either

“Clone W” (Wireless) or “Clone N” (Normal). If

normal cloning was selected or if this is not select-

able, proceed to step 4.

3. With wireless cloning, a screen is then displayed for

entering the P25 Unit ID of the destination (slave)

radio. Enter this ID using the keypad (or the Up/

Down keys) and F2.

4. The clone mode “Zone” or “Complete” is then

selected. Select the desired mode. Operation is as

follows:

Zone - This mode allows channel information for

only the selected zone to be transferred. Informa-

tion programmed on the Global, Radio Wide, and

By System screens is not changed. A list of the

current conventional zones is displayed. Select the

desired zone by highlighting it and pressing the F2

key. A selected zone is indicated by an asterisk (*).

Scroll to “OK” and press F2 to begin the data

transfer. The selected zone in the slave radio is

overwritten. Previously, multiple zones could be

selected and they were appended to those in the

slave radio.

Complete - This mode transfers all conventional

programming information. This includes informa-

tion on the Global, Radio Wide, and By System

screens. Simply highlight “Complete” and press the

CONVENTIONAL MODE FEATURES

F2 key to begin the data transfer. This mode over-

writes all this information currently in the slave

radio. None of the previous information is retained

except for the IDs as described in Section 5.16.1.

5.17 PROJECT 25 MODE FEATURES

NOTE: The following features are unique to

conventional P25 channels.

5.17.1 UNIT ID CODE

Each radio that operates on Project 25 (digital)

channels is programmed with an eight-digit unit ID.

This ID is unique for each radio and can be any

number from 1-16,777,216. When power is turned on

with a Project 25 channel selected, this ID is briefly

displayed.

5.17.2 GROUP ID CODE

Each Project 25 channel is programmed with a

group ID that determines which group of radios will

receive the call. A call is received on a channel if a

selected or scanned channel is programmed with that

ID and the correct NAC is detected (see following).

Group IDs can be any number from 0-65,535. Group

ID detect can be disabled by the Normal/Selective

squelch function described in Section 5.5.2 or the

monitor mode described in Section 5.3

5.17.3 NETWORK ACCESS CODE

Project 25 conventional channels also use a NAC

(Network Access Code) to control which calls are

received on a channel. The NAC can be 0-4095, and

each transmit and receive channel can be programmed

for a different code. Other operation, such as moni-

toring before transmitting, is similar to that of analog

channels. NAC (and group ID) detect can be disabled

by the monitor mode described in Section 5.3.

5.17.4 P25 GROUP CALLS

P25 group calls are placed by simply selecting the

channel programmed for the desired group, monitoring

the channel if required, and transmitting.

When a P25 group call is received, the alias (or

frequency) of the selected channel is displayed. The

radio can be programmed so that the following are

also displayed for 0.5-7.0 seconds or continuously

during the call.

P25 PTT ID- The unit ID of the radio placing the

call is displayed.

P25 Talk Group - The alias of the talk group on

which the call is being received is displayed.

User Group ID - If the group ID of the call being

received is included in a preprogrammed User

Group ID list, the alias programmed in that list for

that group is displayed.

Changing a Channel Talk Group

If the Digital Talk Group Select option switch or

Select TG menu parameter is programmed, the talk

group assigned to a channel can be changed by the

user. The new talk group continues to be assigned to

the channel until it is manually changed again (cycling

radio power or selecting another channel does not

reselect a default talk group). Change the talk group

assigned to a channel as follows:

1. Select the channel to be changed.

2. To select the talk group from the list of programmed

talk groups, briefly press the Talk Group Select

option switch or select the Select TG > ID List

menu parameter. Then press the Up/Down switch

until the alias of the desired talk group is displayed.

If talk group selection has been disabled on the

channel by programming, “NO LIST” is displayed,

a tone sounds, and no change occurs. Press the F2

switch to select the talk group and return to normal

operation.

3. To enter a new talk group number from 1-65,535,

press and hold the Talk Group Select option switch

or select the Select TG > Enter ID menu parameter.

Enter the desired talk group directly using the

keypad. If less than five digits are entered, press the

F2 switch to select the talk group and return to

normal operation.

5.17.5 P25 UNIT CALLS

Unit Calls (also called Individual Calls) can be

placed to a specific radio on a Project 25 channel if the

Unit Call option switch or menu parameter is

CONVENTIONAL MODE FEATURES

programmed. Only the individual ID of the target radio

is sent (a talk group ID is not sent). The radios that can

be called are preprogrammed in the Unit Call list.

To receive a Unit Call, the RF channel of the call

must be selected or scanned and the correct NAC and

unit ID must be detected. The ID of the calling radio is

then transmitted back. To respond to the call, the radio

must be programmed with the Unit ID option switch

or menu parameter, and have a Unit Call programmed

for the ID of the calling radio.

Place and receive a Unit Call as follows:

1. To transmit a Unit Call, press the Unit Call option

switch or select the Unit Call menu parameter. The

alias (tag) of the last Unit Call is displayed.

2. If required, press the Up/Down switch to display the

desired call. The alias and ID of the calls that have

been programmed are alternately displayed.

3. Press and then release the PTT switch. Ringing is

then heard and “WAIT” displayed to indicate that

the radio is being rung. To disable this ringing but

not the call, briefly press the PTT switch again.

Ringing occurs for 20 seconds or until the call is

answered, whichever occurs first.

4. When a Unit Call is received, two beeps sound (if

tones are enabled), and “Call Rcvd” and the alias of

the unit ID are alternately flashed.

5. To respond, select the Unit Call mode by pressing

the Unit Call option switch or selecting the menu

parameter. The following operation then occurs:

•If a unit call has been programmed with the ID of

the calling radio, it is automatically selected. A

response can then be made without changing the

selected channel.

•If no Unit Call has been programmed with the ID

of the calling radio, a response cannot be made in

this mode.

•If the call timer times out (set by programming) or

the channel is changed before a response is made,

the unit call mode is exited.

5.17.6 P25 CONVENTIONAL TELEPHONE

CALLS

General

Telephone calls can be placed and received on

P25 conventional channels. This feature allows tele-

phone calls to be placed and received over the public

telephone system using your radio. Telephone calls are

programmed to operate in one of the following modes:

•Disabled

•Answer-only capability

•List only - Telephone numbers can be selected

from a preprogrammed list only (direct entry

using the keypad is not allowed)

•Unlimited - Telephone numbers can be selected

from a list and also dialed directly entered using

Both limited and DTMF keypad models can place

telephone calls by recalling the telephone number

from a preprogrammed list as just described. However,

only DTMF keypad models can directly dial telephone

numbers using the keypad.

Access/De-Access Codes

P25 conventional telephone calls utilize an access

to access the system when placing a telephone call,

and a de-access code to terminate the call when it is

finished. These codes are preprogrammed in pairs by

the Access/De-Access Code list selected on the

conventional Per System screen, and up to 16 pair can

be programmed. Each conventional P25 channel can

be programmed to automatically select one of these

code pairs. They must match the system codes, and the

default code is *1P(pause)#.

•If the access is successful, a dial tone sounds and

the dialed number is displayed and sent. Either

ringing or a busy signal is then heard as with a

standard telephone call. When the called party

answers, press the PTT switch to talk and release

it to listen (since the radio is half-duplex, it is not

possible to talk and listen at the same time).

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES

Each time the PTT switch is released, a go-ahead

tone is sent to the landside party to indicate when

they can respond. To dial a number after the

connection is made, press the PTT switch and dial

the number using the microphone keypad.

•If the selected telephone number is not valid,

“INVALID” is displayed and an alert tone sounds.

Select a valid number.

•If the system is busy, “BUSY” is displayed and

the busy tone sounds. The call will automatically

proceed when the system becomes available.

•If you are out-of-range or the radio cannot be

accessed for some reason, “NO PHONE” is

displayed and an alert tone sounds.

•If the interconnect call you are making or the

selected secure mode is not authorized,

“REJECT” is displayed and an alert tone sounds.

•If your radio does not have the proper encryption

key, “KEYFAIL” is displayed and the call must

be made in the clear mode using the Clear/Secure

option key or menu parameter (if encryption is

selectable on the channel). Otherwise, load the

proper encryption key.

4. When the telephone call is finished or if it could not

be completed for some reason, end it by pressing the

Phone option key or F1 (Exit) key.

6.6.3 ANSWERING A TELEPHONE CALL

1. When a telephone call is received, “ringing” similar

to a standard telephone is heard and “PHONE” is

displayed.

2. To answer the call, press the Phone option switch or

select that menu parameter and press the PTT switch

to talk and release it to listen. Since the radio oper-

ates half duplex, it is not possible to talk and listen

at the same time.

3. When the call is finished, end it by pressing the

PHONE option switch or F1 (Exit) key.

6.7 CALL ALERT

6.7.1 GENERAL

The Call Alert™ feature allows pages to be sent

and received. With SMARTNET/SmartZone opera-

tion, either the Enhanced Private Conversation™ or

Standard Private Conversation mode may be

programmed depending on the capabilities of the radio

system. With P25 Trunked operation, operation is

similar to the enhanced mode.

6.7.2 ANSWERING A PAGE

1. When a page is received, five beeps sound and

“PAGE” is displayed. The ID of the radio paging

you is stored as the last ID received.

2. To clear or ignore the page, press any option switch.

If the PTT switch is pressed, a group call is placed

on the selected channel.

3. To answer the page as a private call (see Section

6.5), press the Private Call option switch or select

that menu parameter and the alias of the radio

paging you is displayed. Press the PTT switch and

respond. One of the conditions that follow may also

occur:

Enhanced Private Conversation Mode

•If the radio being called is on the air, ringing is

heard until the called party answers or for 20

seconds, whichever occurs first. If no answer

occurs within 20 seconds, a continuous tone

sounds and “NO ANS” is displayed.

•If the radio being called is not on the air, a contin-

uous tone is heard instead of ringing and “NO

ACK” is displayed.

Standard Private Conversation Mode

•If the radio being called is not on the air or does

not answer, you will simply not hear a response.

4. When the call is finished or it could not be

completed for some reason, end it by pressing the

Private Call option switch or the F1 (Exit) key.

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES

6.7.3 INITIATING A PAGE

1. With a SMARTNET/SmartZone or P25 Trunked

channel selected, momentarily press the Call Alert

option switch or select that menu parameter. The

alias of the last ID called is displayed.

2. If required, press the Up/Down switch to display the

desired radio. The alias of each number is

displayed.

3. Press the PTT switch or the F2 key and one of the

following occur:

•If five beeps sound, the system received the page

and the paged radio is on the air and received it.

The page mode is automatically exited.

•If the system received the page but the called

radio is not on the air, a single beep sounds and

“NO ACK” is displayed 6 seconds after the PTT

switch is pressed. Auto exit then occurs.

6.8 MESSAGING

NOTE: This feature is not available with P25 trunked

operation.

The messaging feature allows preprogrammed

messages to be sent to a dispatcher. Up to 16 messages

can be preprogrammed, and they are identified by an

alias. If a Message option switch or menu parameter is

programmed, messages are sent as follows:

1. Momentarily press the Message option switch or

select that menu parameter. The alias of the last

message sent is displayed.

2. If required, press the Up/Down switch to display the

desired message. Then send the message by

pressing the F2 key or momentarily pressing the

PTT switch. One of the following events then

occurs:

•If five beeps sound and “ACK RECVD” is

displayed, the message was received and auto-

matically acknowledged by the system.

•If after five tries the message is not acknowl-

edged, a tone sounds and “NO ACK” is

displayed.

6.9 SENDING STATUS CONDITIONS

The status feature allows you to manually or

automatically send your current status to your

dispatcher. Up to eight status conditions can be prepro-

grammed, and they are identified by an alias. If the

Status option switch or menu parameter is

programmed, status conditions are sent as follows:

1. Momentarily press the Status option switch or select

that menu parameter. The alias of the current status

condition is displayed.

2. To change the current status, press the Up/Down

switch until the desired status is displayed. Then to

send the status, press the F2 (Select) switch or

momentarily press the PTT switch. One of the

following events then occurs:

•If five beeps sound and “ACK RCVD” is

displayed, the status was received and acknowl-

edged by the system.

•If after five tries the message is not acknowl-

edged, a tone sounds and “NO ACK” is

displayed.

6.10 EMERGENCY ALARM AND CALL

6.10.1 INTRODUCTION

Emergency Alarms and Calls are separate func-

tions that can be individually enabled or disabled on

each SMARTNET/SmartZone and P25 Trunked

system. The Emergency option switch (or menu

parameter) is required for these functions. Other emer-

gency features are as follows:

•Emergency Alarms are transmitted on the selected

talk group if emergency calls are disabled, and on

the emergency talk group if emergency calls are

enabled.

•Emergency Call talk group selection priority is as

follows. For example, if a global emergency channel

is not programmed, the emergency talk group of the

selected channel is used and so on.

1. Global (radio wide) emergency channel

2. Emergency group of the selected channel

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES

3. Talk group of the selected channel

4. Announcement group of the selected channel

•The emergency programming of the system to

which that emergency talk group is linked controls

the emergency operation.

6.10.2 EMERGENCY ALARMS

An emergency alarm is a special transmission that

alerts a dispatcher of an emergency situation. It is sent

automatically by simply pressing Emergency option

switch or selecting the Emergency menu parameter.

The system to which the emergency channel is linked

must have Emergency Alarms enabled. If not, Emer-

gency Alarms are disabled. The alarm is sent on the

control channel using Motorola proprietary signaling.

Proceed as follows to send an emergency alarm:

1. If required, select a channel of a system on which

Emergency Alarms are enabled and then press the

Emergency option switch or select that menu

parameter. The radio then automatically transmits

the emergency alarm.

2. Either Normal or Silent operation can be

programmed. With the Normal mode, the red LED

lights, the emergency tone sounds, and

“EMERGNCY” flashes in the display. This indica-

tion continues to flash until the alarm mode is ended

(see step 4). If silent programmed or the Surveil-

lance mode is selected (see Section 4.7), none of

these indications occur. If “No Receive Activity

During Emergency” is programmed, receive audio,

the front panel LED, and receive icons are disabled

in the receive mode.

3. When the emergency alarm is acknowledged, “ACK

RCVD” is briefly displayed and the emergency

acknowledge tone (two beeps) sounds. Silent opera-

tion may also be programmed in which case no tone

sounds and there is no indication that an acknowl-

edgment occurred.

4. The radio continues to transmit this message until an

acknowledgment is received or the programmed

number of attempts have been made. The emer-

gency alarm mode is exited when radio power is

cycled or by pressing and holding the Emergency

option switch.

6.10.3 EMERGENCY CALLS

General

An emergency call urgently requests access to a

voice channel (an emergency tone usually does not

sound at the console). An emergency call is placed by

pressing the PTT switch after pressing the Emergency

option button or selecting the Emergency menu

parameter. If the Emergency Hot Mic feature is

enabled, the emergency call is automatically trans-

mitted without having to press the PTT switch (see

following description). The system to which the emer-

gency channel is linked must have Emergency Calls

enabled.

Emergency Hot Mic

If Emergency Hot Mic has been enabled for

emergency calls, automatic transmitting occurs with

microphone audio unmuted without having to manu-

ally press the PTT switch. The automatic transmit

period is programmed for 10-120 seconds in 10-

second intervals. If this feature or emergency calls are

not enabled by programming, automatic transmitting

does not occur. This feature is initiated only on the

first press of the Emergency switch. Subsequent

presses do not trigger automatic transmissions. To

reset this function, the channel must be changed or

power cycled.

Placing an Emergency Call

1. If required, select a channel of a system on which

Emergency Calls are enabled and press the Emer-

gency option switch or select that menu parameter.

The Emergency Alarm is then sent as described in

Section 5.10.2 if applicable.

1. The emergency mode is indicated when “ACK

RCVD” is briefly displayed and then

“EMERGNCY” and the emergency talk group are

alternately displayed.

2. If the preceding Emergency Hot Mic feature is

enabled, the call is automatically transmitted

without pressing the PTT switch. If it is disabled,

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES

press the PTT switch and begin speaking as with a

standard call.

3. All group calls which follow are then emergency

calls (private, telephone, and call alert calls are not

allowed). If the channel is changed, the call is made

on the emergency talk group programmed for the

new channel. If the Surveillance Mode is enabled

(see Section 4.7), all indicators, lights, and tones are

disabled. If “No Receive Activity During Emer-

gency” is programmed, receive audio, the front

panel LED, and receive icons are disabled in the

receive mode.

4. To exit this mode, cycle radio power or press and

hold the Emergency switch.

6.10.4 EMERGENCY MAN-DOWN FEATURE

This feature requires a special man-down switch

(currently available only from third-party vendors)

that is attached to the accessory connector of the radio.

Then if this feature is enabled by programming and the

radio is in a horizontal position for longer than the

programmed time (0-63 seconds), an emergency

condition is triggered the same as if the Emergency

switch was pressed. The emergency can be canceled

by a press and release of the Emergency switch. Note

that accessories such as speaker-microphones cannot

be used with this feature.

6.11 FAILSOFT OPERATION

If a failure occurs in the SMARTNET/Smart-

Zone or P25 Trunked system so that it cannot be used,

the system directs the radio to automatically enter the

failsoft mode. When in this mode, “FAILSOFT” and

the alias of the selected channel are alternately

displayed. A failsoft tone may also be heard,

depending on how the repeater is programmed.

When in the failsoft mode, operation is in the

conventional mode on the preprogrammed failsoft

channel (a different failsoft channel can be

programmed on each talk group). If a transmission is

attempted before a failsoft channel is located, a contin-

uous tones sounds until the PTT switch is released.

When the radio system returns to normal operation,

this is automatically detected and normal operation

resumes.

6.12 SMARTNET/SMARTZONE/P25 TRUNKED

SCANNING FEATURES

6.12.1 GENERAL

Scanning on a SMARTNET/Smartzone and P25

Trunked systems is called Priority Monitor Scan. The

following are unique features of this type of scanning.

For general scanning information applicable to all

operating modes, refer to Sections 4.8 and 4.9.

•Scanning is turned on and off by the Scan option

switch or menu parameter. Talk groups (channels)

can be programmed so that scanning automatically

starts when the talk group is selected (Autoscan).

•When responding to calls in the scan mode, the

programming of the Talkback Scan parameter deter-

mines if a response always occurs on the talk group

of the call (Active Group) or the Selected Group if

they are different. Transmissions at other times

always occur on the selected talk group.

•Each talk group can be programmed to select one of

the programmed scan lists or “No List” (scanning is

disabled). If scanning is enabled and the selected

channel does not permit scanning, it is automatically

enabled again when a channel is selected that

permits scanning.

•Up to 256 scan lists, each with up to 512 talk groups

from the same system can be programmed. The

selected scan list can be temporarily changed and

edited as described in Section 4.9.1.

•In addition to calls on channels in the scan list,

pages, private/unit calls, and telephone calls are

received while scanning. Private and telephone calls

are not interrupted by priority messages.

6.12.2 PRIORITY TALK GROUP SAMPLING

One talk group in the scan list can be designated a

priority talk group by programming or it can be the

selected talk group. When scanning, messages on a

non-priority talk group are interrupted by messages on

the priority talk group. Priority scanning must also be

supported at the system level for it to occur as

programmed in the radio.

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES

6.13 DYNAMIC REGROUPING

The dynamic regrouping feature allows a

dispatcher to change the current talk group or switch

radios to a predefined regrouping channel to receive an

important message. When the console issues a regroup

order, the radio switches to the preprogrammed

regroup talk group.

If the Cancel Dynamic Regrouping option switch

or menu parameter is programmed, it can be used to

exit the dynamic regrouping mode if desired.

Otherwise, if the lock mode was not specified, the

selected talk group can be manually changed and the

previous talk group is reselected if power is cycled. If

a locked regroup command is received, the displayed

talk group cannot be changed manually or by cycling

power. It can be changed only after a clear order is

received from the console.

Dynamic regrouping operates as follows:

1. When this command is received, alternating tones

sound and the radio automatically changes to the

regrouping channel and “DYN REGRP” is

displayed.

2. Manually select the channel corresponding to that

alias. If this is not done, transmission still occurs on

the new channel, but the alternating tones sound

each time the PTT switch is pressed.

3. Talk and listen as usual. When dynamic regrouping

is canceled by the dispatcher, a short tone sounds. If

a standard channel is not selected after this occurs,

transmission is not allowed if the talk group is

assigned as a dynamic regrouping talk group only. If

it is assigned as a normal talk group, normal trans-

missions are allowed.

6.14 SMARTZONE AND P25 TRUNKED

UNIQUE FEATURES

6.14.1 INTRODUCTION

As described in Section 3.9.3, the SmartZone®

mode provides wide area coverage by allowing

roaming between SMARTNET and conventional sites.

The P25 Trunked mode can provide access to a single

trunked site or roaming between several trunked sites.

Operation in these modes is the same as just described

in the preceding sections (6.1-6.13) with the following

additional features:

6.14.2 BUSY OVERRIDE

The busy override feature is enabled at the system

level by the system manager and is not a program-

mable radio feature. It allows a call to be placed even

if not all sites you are calling have a free traffic

channel. The only sites guaranteed to be included are

the Critical Sites and the sites where a Critical User is

located. This feature operates as follows:

1. Assume that you have attempted to place a call and

the system was busy (“BUSY” displayed and busy

tone sounded).

2. Release the PTT switch and then press it for 5

seconds or more. If a chirp tone sounds with the PTT

switch pressed, busy override is occurring.

NOTE: Remember that not all members of the talk

group are receiving your message. Missing

members will start receiving your message as

channels become available.

6.14.3 SITE TRUNKING

Site trunking occurs when a site can no longer

participate in wide area trunking. It is disconnected

from other sides and only supports calls with other

radios on that site and cannot route audio to other

sites. When site trunking is occurring, the radio

searches for other sites that may provide wide area

coverage.

Site trunking ends when a wide area coverage site

is located, the current site is operating again as a wide

area coverage site, an out-of-range condition occurs,

or the failsoft mode is entered. The radio can be

programmed so that “Site Trunking” is displayed and/

or an alert tone sounds when site trunking occurs.

SmartZone and P25 trunked systems can be

programmed for “Disable Site Trunking Operation”.

The radio is then not allowed to start or operate on a

site trunking site. If a site goes into site trunking, the

radio leaves that site’s control channel and attempts to

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES

find another valid wide area site. If no wide area site is

available, the radio displays “Out-of-Range”. If a site

adjacent to the current Home Site was in site trunking

but then enters wide area trunking, it is evaluated to

determine if it should move to that site as a better site.

6.14.4 DETERMINING CURRENT SITE AND

SEARCHING FOR NEW SITE

To display the RSSI level of the current site, press

the Site Search option switch or select that menu

parameter. The display then indicates the current site

number as “SITE xx” and the RSSI level as “RSSI

xx”. This mode is then automatically exited.

To scroll through the other programmed sites,

press and hold the Site Search option switch while

“SITE xx” or “RSSI xx” is displayed. If site lock is on

when site search is entered (see following), the radio

will be locked on the new site when this function is

exited.

6.14.5 LOCKING/UNLOCKING A SITE

It is sometimes desirable to stay on a site. To

prevent the radio from searching for a new site, lock it

on the current site by pressing the Site Lock option

switch or selecting that menu parameter. The display

then momentarily indicates the site alias to indicate

that the current site is locked (“x” is the current site

number). To unlock the site, press the Site Lock switch

again or the F2 (Select) key and “UNLOCK” is

momentarily displayed.

6.14.6 ZONEFAIL SITE LOCK

This is an optional feature that can be enabled

only by factory programmed. It is not programmed by

the PCConfigure software, and does not require any

special inputs from the infrastructure to operate. This

feature is intended to prevent some of the confusion

resulting from a site controller failure. When this

occurs, all sites go into the Site Trunking mode and

radios continue to roam normally according to RSSI

level. The result is that the various radios selected by a

particular talk group may be operating on different

sites and are unable to talk to each other (see Section

6.14.3 for more Site Trunking information).

With the Zone Fail Site Lock feature enabled, the

radio continues to roam normally when the system

zone controller is active. However, if the zone

controller fails, this is detected and the Zone Fail Site

Lock mode is entered. The only site the radio is then

allowed to operate on is its home site. If its home site

is not available, “Out-of-Range” is displayed. A zone

controller failure is detected by determining that every

site in the dynamic site list is in Site Trunking.

Currently, this condition must be detected for at least 1

minute for the Zone Fail Site Lock mode to be

selected.

The result of this operation is that all radios with

the same programmed home site are forced to the

home site to communicate which ensures that they can

continue to communicate. If the home site is not avail-

able, the Out-of-Range condition tells the user to

attempt communication on another system or by some

other means.

6.14.7 P25 WIDE AREA SCAN

Introduction

This feature is intended to enhance roaming

performance, especially when system level steering

via radio or talk group permissions is used.

Normal P25 and SmartZone Control Channel Hunt

The following control channel search methods are

normally used to find a control channel:

Short Hunt - The dynamic array of 7 (or 15) adja-

cent sites is searched. This list is saved on power

down and loaded again at power up. It is erased

whenever parameters are downloaded to the radio

by the PCConfigure programmer.

Long Hunt - If no valid control channel is located

by the preceding short hunt method, the radio

searches the list of control channels programmed

into the radio by the PCConfigure programmer.

Full Spectrum CC Scan - If the two preceding

methods do not locate a control channel, every

channel available to the radio is searched.

Talkgroup Steering Via System Access Permissions

In order to use system channel resources more

efficiently, some system operators are using system

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES

access permissions to steer certain talkgroups to

particular sites. For example, a police department may

be allowed to use only Site 1, and a public works

department may be allowed to use only Site 2.

The problem with this operation is that every time

a different talk group is selected, the access permission

may be different and a different site may need to be

accessed. This could result, in a worst case, in a delay

of up to 30 seconds in finding a new site. This could

occur if there are no valid sites for the new talk group

in the dynamic site list.

P25 Wide Area Scan

A feature called Wide Area Scan can be

programmed to minimize the problem just outlined.

This feature is programmed on the Talk Group list

screen selected on the P25 System screen. When Wide

Area Scan is selected, talk group site preferences are

no longer available. However, System Site Preference

lists can still be used. The Wide Area Scan feature

functions as follows:

1. Assume TG1 is selected. If it is the first time this

talk group is selected, normal searching for a control

channel occurs according to the hunt methods

previously described.

2. When another talk group is selected, the active valid

site for TG1 is stored in EEPROM memory.

3. The next time TG1 is selected, the following proce-

dure is performed before performing the normal

hunt methods previously described.

a. The last valid site ID and its receive and transmit

channel numbers are loaded from EEPROM

memory.

b. The dynamic site list is checked to see if any

newer receive/transmit channel information is

available for the last site ID.

c. The best receive/transmit information is used and

the radio checks to see if this control channel is

available.

The result of the preceding operation is that the

radio has a reasonable chance of finding a valid site,

usually on the first try. This greatly reduces access

time, even on systems which have highly restricted

talk group based access.

7.3 SYSTEM OPERATOR PROGRAMMING

As noted several times in this manual, program-

ming determines the availability and specific operation

of many features. This usually refers to the program-

ming performed by the PCConfigure programmer

MISCELLANEOUS

when the radio was set up, not to any programming a

user can perform. If a feature is controlled by a front

panel option switch and that switch is not available, it

is probably not available.

If the Keypad Programming option switch is

available, you can reprogram some conventional

channel parameters. Refer to Section 5.18 for more

information.

7.4 SPEAKING INTO MICROPHONE

For best results, hold the radio about 1-2 inches

from your mouth and speak at a normal conversational

level. Do not shout since it distorts your voice and

does not increase range. Make sure that the PTT (push-

to-talk) switch is pressed before you begin to speak

and released as soon as the message is complete.

7.5 OPERATION AT EXTENDED RANGE

When approaching the limits of radio range, the

other party may not be able to hear your transmissions

and there may be an increase in background noise

when messages are received. You may still be out of

range even though you can hear a message. The reason

for this is that the signal you are receiving is usually

transmitted at a higher power level than the one trans-

mitted by your radio. Communication may be

improved by moving to higher ground or away from

shielding objects such as tall buildings or hills.

7.6 LICENSING

A government license is usually required to

operate this radio on the air.

7.7 RADIO SERVICE

If the radio is not responding to any key presses,

the keypad may be locked. Refer to Section 3.6 for

more information.

If “PASSWORD” is briefly displayed when

power is turned on and you are prompted to enter a

password, the Power-Up Password feature is enabled.

Refer to Section 3.2 for more information.

If “UNPROGRAMD” is displayed, the cause

could be any of the following:

•An unprogrammed channel is selected. Select a

programmed channel.

•The selected channel is programmed for an option

that is not installed or an error in programming was

detected. Reprogram the radio.

If no characters appear in the display, the battery

may be discharged or defective. Try another battery. If

some other problem is occurring, turn power off and

then on again to reset the control logic. Also make

sure that the controls are properly set. If it still does

not operate correctly, return it for service.

NOTE: There are no user-serviceable components in

the radio. Altering internal adjustments can cause

illegal emissions, void the warranty, and result in

improper operation that can seriously damage the

radio.

DETERMINING AVAILABLE OPTIONS

SECTION 8 DETERMINING AVAILABLE OPTIONS

8.1 GENERAL

This manual describes the operation of all

features that are currently available for the 41xx radio.

However, many of these features are optional and

therefore may not be available in your radio. For

example, Project 25 trunked operation is optional and

may not be available.

Availability of optional features is controlled by

factory programming of the control logic. Only those

features that are specifically ordered and enabled in a

particular radio are available for use and can be

programmed. The features controlled by factory

programming are as follows:

P25 Options

•P25 conventional data

•P25 trunked data

•P25 conventional operation

•P25 trunked operation

Encryption Options

•DES

•DES-XL

•DES-OFB

•AES

OTAR Options

•OTAR P25 conventional

•OTAR P25 trunked

Trunking Options

•STAR roaming with P25 trunked operation [1]

•SMARTNET analog operation

•SmartZone analog operation

•Digital SMARTNET/SmartZone

Feature Options

•Keypad programming (Federal Gov’t users only)

•512 channels/talk groups (41xx only, currently

standard)

•DTMF Keypad support (4100 only)

•Zonefail site lock

[1] 4100 radios require that this option be enabled to roam

across zone controller boundaries.

Currently, the only operating mode that is stan-

dard with all models is the conventional analog mode.

Other variables such as frequency range are hardware

dependent instead of software dependent.

8.2 UPGRADING A RADIO WITH NEW

OPTIONS

The capability exists to upgrade radios in the field

with new features. A new feature can be purchased

and a special encrypted code string keyed to the ESN

(Electronic Serial Number) of the radio is then

provided by the E.F. Johnson Company. This string is

in the form of a computer file, and is downloaded to

the radio using the PCConfigure programming soft-

ware. This is initiated by clicking the “Update

Options” button on the Radio Options screen shown in

Figure 8-1.

8.3 USING PCCONFIGURE TO DETERMINE

OPTIONS

To determine what software options have been

enabled in a particular radio, it is recommended that

you use the PCConfigure™ programming software to

read and display what options are installed. Proceed as

follows:

1. Connect the computer to the radio and start the

program as described in the documentation included

with the PCConfigure software.

2. Select the 41xx radio type by selecting menu

parameter Radio > Series > 4100 Portable.

3. To display the Radio Options screen shown in

Figure 8-1, select Transfer > Read Options From

Radio.

4. The check boxes indicate which options are enabled

in the radio. They are for informational purposes

only and cannot be edited.

PASSWORD DESCRIPTION

SECTION 9 PASSWORD DESCRIPTION

9.1 NEW PASSWORD ENHANCEMENTS

9.1.1 INTRODUCTION

A new enhanced password feature is now avail-

able for 4100 portables and 4300 mobiles. The number

of passwords have been increased along with the

number of functions that can be under password

control. The single Power-On password has been

replaced by the following passwords:

•Four Power-On (User x) Passwords

•Download and Upload Passwords

•Master Password

9.2 PROGRAMMING PASSWORDS

9.2.1 GENERAL

With new versions of PCConfigure, the “Pass-

word at Power Up” parameter has been removed from

the Global screen as just described. Passwords are now

programmed using a password management screen

displayed by the Tools > Password Management

menu. The applicable radio must be connected to the

computer and powered up to display this screen.

Password data is transferred and stored in an

encrypted format for security purposes. In addition,

actual passwords are never displayed. They are always

indicated by eight asterisks (********). Therefore, it

is not possible to determine what passwords are in a

radio using the PCConfigure software.

Passwords must be 1-8 characters in length and

consist of the numbers 0-9. Zeros are valid characters

in any location, even as leading characters. Initially, all

passwords are null (deleted) characters. Therefore,

when initially programming a password, no entry is

required in the “Original/Master Password” box.

9.2.2 LOST PASSWORDS

If a password is lost, it can be changed using

PCConfigure by entering the Master password (see

following). If even the Master password is lost or was

not used, all passwords can be erased using the

PCTune software as follows:

1. With PCTune 1.1.1.0 or later, simply select Radio >

Reset Passwords. Only password information is

erased.

2. With earlier versions of PCTune, after starting the

PCTune program, press SHIFT CTRL E to toggle

the following Erase EEPROM function (otherwise it

is grayed and not selectable). Then Select Radio >

Erase EEPROM > Params Only. All password and

personality information is erased, so the radio must

be reprogrammed. NOTE: DO NOT SELECT

“COMPLETE” because that erases all information

and the radio must then be sent back to the factory

to make it usable again.

9.2.3 CHANGING PASSWORD

An assigned password can be changed by the user

if the “Set User Password” option switch or menu

parameter (4100 only) is programmed. Selecting this

function displays prompts for entering and confirming

a new password.

NOTE: With the 4100 portable and 4300 Handheld

Control Unit, it is recommended that a number key not

be used for this function because the password mode is

exited if that key is pressed to enter a number.

9.2.4 PASSWORD ENTRY PROCEDURE

Whenever a password is requested, it is entered as

follows:

43xx Mobile - Rotate and press the Select switch.

41xx Portable - With DTMF keypad models, enter

each number using the keypad and press the F2 (Enter)

key after the last digit is entered. With limited keypad

models, enter each number by pressing the Up/Down

switch and press the F2 key after each digit.

PASSWORD DESCRIPTION

9.3 PASSWORD DESCRIPTION

9.3.1 USER (POWER-ON) PASSWORDS

When a User Password is enabled, it must be

entered each time radio power is turned on. Up to four

different User Passwords (User 1/User 2/User 3/

User 4) can be programmed. Currently, the same radio

features are enabled for each. Entering any User Pass-

word at power up enables normal radio operation.

9.3.2 DOWNLOAD/UPLOAD PASSWORDS

Separate Download (write) and Upload (read)

passwords can be programmed to prevent unautho-

rized downloading or uploading of radio programming

parameters. When one or both of these passwords are

used, the proper password must be entered to perform

the operation. A “User” password is not required to

upload or download parameters.

9.3.3 MASTER PASSWORD

The Master Password overrides all the preceding

passwords. It can be used by a system administrator as

a “pass key” to a password controlled function or to

change a lost or inadvertently changed password.

Master passwords are set up and changed the same as

the other passwords. It does not override the following

Zone Password.

9.4 ZONE PASSWORD

NOTE: The programming and usage of this password

has not changed. It is independent from the preceding

passwords, and programmed in the Zone > Edit Zones

and Channels screen.

A zone password can also be programmed with

the 43xx mobile and 41xx portable. It prevents unau-

thorized reprogramming of zones by keypad program-

ming. When this password is used, it must be entered

before system or channel parameters in that zone can

be changed. The zone password is programmed in the

Edit Zones and Channels screen. This screen is

displayed by clicking the Edit Zone button on the

Zone screen.

A different password can be programmed for

each zone. When a password protected zone is

selected, “PASSWORD” is flashed the first time an

attempt is made to select a system or channel

parameter in that zone. Each digit of the password is

then entered as previously described. The password is

always eight digits long, and after the eighth digit is

entered, system and channel parameters for that zone

can be reprogrammed normally.

SECURE COMMUNICATION (ENCRYPTION)

SECTION 10 SECURE COMMUNICATION (ENCRYPTION)

10.1 GENERAL

10.1.1 INTRODUCTION

This radio may be equipped to provide secure

communication on some or all channels. This feature

encrypts the voice so that it can be understood only by

someone using a radio equipped with a similar encryp-

tion device and encryption codes.

When a secure call is received or transmitted,

is indicated in the display (see Section 10.2.7). If

equipped with the Clear/Secure option switch and the

current channel is programmed to allow switch selec-

tion, secure communication can be manually enabled

and disabled by that switch. Otherwise, channels are

strapped to Clear or Coded operation (see Section

10.3). Secure communication can be programmed on a

per channel or per talk group basis to operate in

various ways. More information follows.

10.1.2 ENCRYPTION ALGORITHMS

SecureNet™

SecureNet encryption digitizes the voice and then

encrypts it using the DES or DVP algorithm. It uses a

64-bit encryption key. The SecureNet protocols

include the following algorithms:

•DVP (Digital Voice Privacy) is an earlier encryption

method that is self synchronizing using cipher feed-

back. It was originally designed to be used by

anyone needing protection from unauthorized

eavesdropping.

•DES (Data Encryption Standard) provides a higher

level of security, and also uses cipher feedback. It

was originally designed to be used only by the

Federal government.

•DVP-XL/DES-XL - A disadvantage of the DVP and

DES encryption types is reduced communication

range when compared to clear voice. The DES-XL

and DVP-XL methods were designed to provide

better range but at the cost of lower voice quality.

They use a different type of feedback called counter

addressing.

•DES-OFB - A form of DES encryption for digital

channels that uses output feedback. This protocol

does not result in the degraded range that occurs

with analog channels.

AES (Advanced Encryption Standard)

A new encryption standard called AES is

replacing DES-OFB encryption on digital (P25) chan-

nels. It uses a 128-, 192-, or 256-bit encryption key

instead of the 64-bit key used with DES. EFJohnson

radios currently support only 256-bit AES keys. The

type of encryption (DES or AES) is determined by the

type of encryption key that is loaded (see Section

10.2), and not by the PCConfigure programming soft-

ware. AES encryption, like DES encryption, is an

optional radio feature that must be purchased and then

enabled at the factory.

10.1.3 ENCRYPTION AVAILABLE WITH

VARIOUS CHANNEL TYPES

Analog Channels

On analog conventional and SMARTNET/Smart-

Zone channels, DES and DES-XL encryption is used

to provide secure communication. The DES-XL type

is available only with later 41xx portables equipped

with the Motorola UCM (Universal Crypto Module).

Digital Channels

On digital Project 25 and SMARTNET/Smart

Zone channels, the DES-OFB or AES protocol is used.

10.1.4 FIPS AND NON-FIPS MODES

FIPS 140-2 is a Federal Information Processing

Standard for encrypted radios used by the Federal

Government. This standard specifies Federal security

10.2 ENCRYPTION KEYS

10.2.1 INTRODUCTION

An encryption key is a cryptographic variable

that is required by the encryption algorithm to encrypt

and decrypt voice or data. To maintain system security,

these keys must be protected from disclosure and also

periodically replaced or updated.

With the AES and DES encryption used by

EFJohnson radios (see Section 10.1.2), the same

encryption key is used by both the encrypting

(sending) and decrypting (receiving) radio. AES

encryption keys are generated from a string of 64

hexadecimal characters, and DES keys are generated

from a string of 16 hexadecimal characters. Another

four hexadecimal characters are used to specify the

key ID. Multiple keys can be loaded into a radio using

OTAR or manual loading.

When an encrypted message is transmitted, the

encryption Algorithm ID (ALID) and key ID (KID)

are usually included in the message. This tells the

receiving radio which key and algorithm must be used

to decrypt the message.

If an attempt is made to transmit a secure

message without loading the corresponding key,

“KEYFAIL” is displayed. The message must then be

transmitted in the clear mode (this is possible only if

the channel is strapped to “switchable”) or the key

must be loaded.

10.2.2 KEY AND ALGORITHM IDS

Each encryption key is programmed with a Key

ID (also called Logical ID). This ID plus the algorithm

ID (ALGID) is transmitted in the message. The radio

receiving the message must have a key programmed

with the same IDs in order to decrypt it.

10.2.3 PID/SLN KEY MANAGEMENT MODES

NOTE: The term “SLN” from the Project 25 specifica-

tion is equivalent to “CKR” (Common Key Reference)

also used to define this parameter.

The channels, talk groups, and other calls that use

encryption are linked to a specific Physical ID (PID)

when the radio is programmed using the PCConfigure

programming software. For example, Zone 1, channel

1 could be programmed to select the key in PID 1 and

Zone 1, channel 2 could select the key in PID 3. The

PID ranges are 0-15 when the PID mode is selected,

and 1-16 when the SLN mode is selected (see

Figure 10-1).

PID or SLN key management modes can be

programmed on the Global programming screen. More

information on these modes follows.

PID Mode - The PID mode can be used only when

keys are loaded using the Motorola KVL 3000

SECURE COMMUNICATION (ENCRYPTION)

keyloader. When this mode is selected, keys are loaded

directly into a PID of 0-15 that corresponds to the PID

programmed for each channel (if applicable). A Keys

Table is not programmed with this mode.

SLN Mode - The SLN mode must be selected is either

OTAR (Over-The-Air-Rekeying) or the EFJohnson

System Management Assistant (PDA keyloader) is

used. It can also be used if OTAR is not used. With

this mode, keys are loaded into a SLN (Storage Loca-

tion Number), typically from 0-4095. A Keys Table

must then be programmed to link channel PIDs to a

specific SLN.

The use of this type of indirect linking allows keysets

and key IDs to be changed via OTAR while keeping

the mapping from the channel or talk group the same.

For example, as shown in Figure 10-1, PID 4 selects

SLN 24 which selects key slot 24 in both keysets. This

slot contains Key ID 69 in Keyset 1 and Key ID 91 in

Keyset 2. Only one keyset is active at a time.

10.2.4 MAINTAINING KEYS IN MEMORY

The radio may need to be connected to a constant

power source to preserve the encryption keys in

memory. The programming of the Infinite Key Reten-

tion parameter determines if keys are permanently

stored in memory or erased soon after power is

removed.

When Infinite Key Retention is enabled, keys are

stored in memory and are not lost when power is

removed. If it is disabled, they are maintained only

until the storage capacitance discharges. With 4100

models, storage capacitors maintain the supply voltage

(and encryption keys) for approximately 30 seconds

without power applied. Therefore, when changing the

battery, make sure to reattach another within 30

seconds.

With 5300 models, the keys are maintained for

approximately 8 hours with this feature disabled.

However, a tamper switch causes immediate key

erasure when the radio cover over the logic board is

removed.

10.2.5 ENCRYPTION KEY SELECT

NOTE: This feature is available on conventional

channels only.

When multiple encryption keys are programmed

(see preceding information), the Key Select option

switch can be programmed to allow selection of

another key for the current channel. This feature

changes the PID (hardware location) of the key, and

the change is permanent (cycling power or selecting a

different channel does not reselect the original key).

Therefore, to switch back to the original key, it must

be manually reselected. Proceed as follows to select a

key:

1. Press the Key Select switch or select that menu

parameter and HWKEY x is displayed. The “x”

indicates the current key PID selection.

2. Press the Up/Down switch to display the desired key

and then press the F2 (Select) key to select it. Press

the F1 (Exit) or Key Select switch again to return the

display to normal operation.

10.2.6 ENCRYPTION KEY ERASE

A Key Erase menu item can be programmed that

allows the user to permanently erase all stored keys. If

OTAR TEK and KEK keys are stored, all keys of both

types are erased. This function can be used to ensure

that unauthorized encrypted calls can no longer be

placed or received by a radio.

10.2.7 ENCRYPTION ICON OPERATION

Basically, the encryption icon is on continu-

ously whenever a secure call is received or trans-

mitted. Other operation is as follows:

•When a secure call is received on a digital channel

in either the secure or clear mode, this icon flashes.

•When a clear call is received on a digital channel in

the secure mode, this icon is on continuously.

•There is a programmable option on the Radio Wide

screen to sound a beep whenever a secure call is

received on a clear channel.

10.3 CLEAR/SECURE STRAPPING

10.3.1 TRANSMIT MODE OPTIONS

The following transmit options are available

when encryption is selected:

SECURE COMMUNICATION (ENCRYPTION)

Clear - All calls are in the clear mode unless

responding to a secure call. If the response is then

made within the delay time (see Section 4.8.4), it

occurs in the secure mode.

Secure - All calls are made in the selected secure

mode.

Switched - The mode is selected by the Clear/Secure

switch. When the clear mode is selected by this

switch, “CLEAR” is flashed, and when the secure

mode is selected, “SECURE” is flashed.

If the channel has been strapped “Clear” and the

option switch selects the “Secure” mode on power up

and a transmission is attempted, “Clear Only” is

displayed and transmitting is disabled. Likewise, if the

channel is strapped “Secure” and the option switch

selects the “Clear” mode on power up and a transmis-

sion is attempted, “Secure Only” is displayed and the

transmitter is disabled.

The radio can be programmed to ignore the

“Clear” or “Secure” switch setting (“Ignore Clear/

Secure Switch When Strapped” selected on Global

screen). These preceding indications then do not occur

and transmissions always occur in the strapped mode.

NOTE: If all channels/talk groups are strapped clear

or secure and no Clear/Secure option switch or menu

parameter is programmed, this parameter must always

be selected (see following).

If the Clear/Secure switch or menu parameter are

not programmed, the radio is always in the last known

state (usually Clear) and there is no way to change it.

For example, if the last known state is Clear and this

parameter is not selected, it is never possible to

transmit a Secure message on a channel strapped

Secure because all that happens is transmitting is

disabled, an error tone sounds, and “Sec Only” is

displayed.

10.3.2 RECEIVE MODE OPTIONS

The following receive options can be

programmed with conventional operation. With

SMARTNET/SmartZone and P25 Trunked operation,

encrypted calls are received if the proper key is

programmed.

No Autodetect - Only signals coded like the transmit

signals are received.

Secure Autodetect - Both clear and secure signals are

automatically detected. This mode is automatically

selected if the transmit mode is switch selectable.

Proper Key Autodetect

Analog Channels

When this feature is disabled and a message is

received with the wrong key, the audio unmutes

and garbled (encrypted) audio is heard. However, if

this occurs with this feature enabled, the audio

remains muted.

Digital Channels

When this feature is enabled and a message is

received with a different key, but the key resides in

the radio, the audio is decrypted and received

normally even though the key is assigned to a

different talk group. If this feature is disabled or the

key does not reside in the radio, the audio remains

muted.

10.3.3 TALK GROUP ENCRYPTION OVERRIDE

On conventional digital (P25) channels, the

encryption strapping mode and PID are programmed

on a per talk group basis similar to the trunked modes

(SMARTNET/SmartZone/P25 Trunked). However,

with this mode only, there is the option to override the

talk group encryption programming and program it on

a per channel basis. Therefore, if desired on conven-

tional digital channels, encryption can be programmed

differently for each channel. Conventional analog

channel encryption is always programmed on a per

channel basis.

10.4 OTAR (OVER-THE-AIR REKEYING)

10.4.1 INTRODUCTION

OTAR stands for “Over-The Air-Rekeying”. This

is the process of sending encryption keys and related

key management messages over-the-air to specific

radios. The advantage of OTAR is that it allows these

keys to be quickly and conveniently updated when

SECURE COMMUNICATION (ENCRYPTION)

necessary. It is no longer necessary to periodically

travel to the radio location or bring the radio into a

maintenance facility to load new keys.

The actual OTAR rekeying functions are

performed by a Key Management Facility (KMF) that

sends Key Management Messages (KMM) to the

radios. These messages are themselves encrypted

using a unique key. Radios must be OTAR-compatible

and programmed for OTAR for this type of rekeying to

occur.

Currently, OTAR is available only on P25

conventional channels, and to program DES-OFB and

AES keys (future programming on P25 trunked chan-

nels is planned). It is not used on SMARTNET/Smart-

Zone channels or to load DES/DES-XL keys.

10.4.2 ENCRYPTION KEY TYPES

There are two types of keys used with OTAR:

TEK (Traffic Encryption Key) - The key used to

encrypt voice and data traffic. All radios using encryp-

tion must have at least one of these keys. This is also

another name for the keys used without OTAR.

KEK (Key Encryption Key) - The key used to

encrypt keys contained in OTAR Key Management

Messages (KMMs). All radios which use OTAR must

contain at least one of these keys. The KEK used to

decrypt/encrypt keys in an OTAR message is defined

by the algorithm and key IDs transmitted in the

decryption instructions field. A KEK may be unique to

a particular radio (UKEK) or common to a group of

radios (CKEK).

10.4.3 KEYSETS

To simplify key management, a number of keys

may be grouped together in a keyset. A keyset is

simply a set of one or more keys of the same type

(either TEK or KEK). Keysets are identified by Keyset

IDs, and the upper four bits of this ID specify the

crypto group (see next section).

The KEK keyset is considered always active and

is ID 255. Two TEK keysets are normally used, and

one is always active and the other inactive. This allows

the inactive keyset to be replaced without interrupting

operation. One is Keyset ID 1 and the other Keyset ID

2. With EFJohnson radios, each keyset can contain up

to 128 keys, but less than 16 are normally used for

optimum keying efficiency and because only up to 16

can be selected by the radio.

The active keyset is usually selected by the Key

Management Facility. It can also be selected by the

keyloader function of the EFJohnson SMA

(Subscriber Management Assistant) or by the user if

the Change Keyset option switch or menu parameter is

programmed. Automatic keyset changeovers are not

supported by EFJohnson radios. In the SLN mode (see

Section 10.2.3), two TEK keysets can be used if

desired even if OTAR is not used.

A diagram of a keyset is shown in Figure 10-2.

Some information may be optional as shown. The

41xx portable does not support or use the Update Item

and Time/Date parameters.

Figure 10-2 Keyset Diagram

10.4.4 CRYPTO GROUPS

A crypto group contains up to 16 keysets of the

same type of key, either TEK or KEK (see Section

10.4.2). However, only two keysets are typically used

as just described. Crypto groups are used to help

manage keys such as when a radio uses keys with

different active times or multiple algorithms.

Currently, only one crypto group is supported, and it is

always ID 0. As shown in Figure 10-3, the crypto

group ID is the upper four bits of both the SLN and

Keyset IDs.

radios within the radio system. One of the main tasks

of the KMF is to maintain a data base of information

Figure 10-3 Encryption Parameter IDs

contained in each radio. This information may include

the following:

•TEKs (main Traffic Encryption Keys)

•KEKs (Key Encryption Keys) used to encrypt

OTAR messages

•Keysets (groups of TEKs or KEKs)

•Crypto groups (groups of keysets)

•Cryptonets (groups of radios using same keys)

•Individual and group Radio Set Identifiers (RSIs)

•List of probable lost or stolen radios

The KMF performs OTAR functions by

exchanging Key Management Messages (KMMs) with

the radios. Both the KMF and radio can originate

messages. Some functions performed by the KMF are

as follows:

•Loading new keys

•Modifying keys

•Initiating keyset switch overs

•Modifying keyset attributes

•Deleting one or more keys to remove a radio from a

cryptonet)

•Deleting all keys (zeroize) when a radio may be lost

or compromised

•Determining if a radio is on the air and reading key

information

•Changing individual and group RSIs

10.4.6 MESSAGE NUMBER PERIOD (MNP)

One of the parameters that is programmed in a

radio utilizing OTAR is Message Number Period

(MNP). This parameter is programmed as described in

Section 10.5.2. This parameter is used to minimize the

possibility of someone sending messages to “spoof”

the system. The MNP is used as follows.

Every message sent out has a message number.

The message number increments by one with each

message sent. The MNP is the maximum difference

allowed between messages. For example, if the MNP

is set to 1000 and the last message number received by

the radio is different by more than 1000 from the

current message number, the current message is

ignored. If the MNP is set to 65535, message numbers

are ignored.

When determining this number, consider the like-

lihood of someone trying to spoof the system by

retransmitting recorded messages and then adjust the

MNP accordingly. The higher the risk, the smaller the

MNP should be. A disadvantage of setting a low MNP

is that the chance of blocking out intended messages

becomes higher. In addition, traffic level and terrain

contribute to lost messages and should also be consid-

ered when selecting this number.

A setting of 1000 is a good compromise because

it blocks out real old messages but is unlikely to affect

anything intentionally sent out by the system (1000

messages sent to a single radio is not likely to occur in

a system in less than a year with normal usage).

10.4.7 DEFINITIONS

Algorithm - Refers to the specific encryption standard

(DES or AES) that is used to encrypt a message. Each

standard uses different calculations to perform the

encryption (see Section 10.1.2).

Algorithm ID (ALGID) - Identifies the algorithm

(DES or AES) used to encrypt a message. This ID and

the Key ID are transmitted with each message to

uniquely identify the key being used.

Black - Refers to information that is encrypted. The

opposite is “Red” which refers to unencrypted infor-

mation.

Common Key Encryption Key (CKEK) - This is a

KEK common to a group of subscriber units which

share the same encryption keys (are part of same

crypto group). These keys can be the DES or AES

Crypto Group ID

(4-Bit = 0-15/0-F)

Keyset ID

SECURE COMMUNICATION (ENCRYPTION)

type. The use of a common key allows the subscriber

units to be rekeyed by the KMF using one Key

Management Message. Refer to “KEK” for more

information.

Common Key Reference (CKR) Group - Same as

Storage Location Number (SLN).

Crypto Group - A group of up to 16 keysets

containing the same type of keys (either TEK or

KEK). Although a crypto group can contain up to 16

keysets, only two are normally used. Only one keyset

in a crypto group is active at a time. EFJohnson radios

currently support only one crypto group.

Cryptographic Variable - The variable used by a

cryptographic algorithm to encrypt a message. Also

called a “key”.

Currency - Relates to the need for key updates. If a

subscriber unit is current, it does not require a key

update at the current time. If it is not current, the KMF

has new keys for that subscriber unit or CKR group

have not been sent or have been sent but not acknowl-

edged.

Group Rekeying - The process of changing the keys

in several subscriber units with a single message

addressed to the group rather than changing each

subscriber unit separately. This addressing is done

using a group RSI. Group rekeying reduces system

overhead and makes rekeying more efficient.

Subscriber units in the same group must be

programmed with a common KEK (CKEK) and use

the same TEKs.

Key - A variable used by a cryptographic algorithm to

encrypt voice or data. Also called “Cryptographic

Variable”.

Key Encryption Key (KEK) - A key used to encrypt

keys contained in Key Management Messages

(KMMs) during OTAR. These messages may them-

selves be encrypted by the currently active TEK.

These keys can be the AES or DES type. There are

KEKs unique to a subscriber unit (UKEK) and

common to a group (CKEK). The other type of key is

the Traffic Encryption Key (TEK) used to encrypt

voice and data messages.

Key ID - This is a 16-bit (four hex digit) number iden-

tifier from 1-65535 for an encryption key which

allows the key to be identified without revealing the

actual key variable. This ID and the Algorithm ID

uniquely identify a key within the KMF or subscriber

unit. Therefore, two keys can have the same ID if they

have different algorithm IDs and vice versa. The Key

ID and Algorithm ID are usually transmitted with a

message to identify the key that must be used to

decrypt it. Key ID 0 is not used with OTAR.

Key Management Facility (KMF) - The equipment

and software which provide OTAR and related key

management services to the subscriber units.

Key Management Message (KMM) - These are the

messages composed by the KMF to send encryption

information to subscriber units via the keyloader or

OTAR. KMMs are themselves encrypted using two

layers of encryption: inner and outer. The inner layer

of encryption is the KEK and the outer layer is the

TEK. At this layer, the KMMs are also included in a

Common Air Interface (CAI) message which adds

another layer of addressing. In addition, a Message

Authentication Code (MAC) is used.

Keyset - A group of keys of the same type (KEK or

TEK) that are managed as a single entity (they can be

updated, deleted, and rekeyed with a single

command).

Keyset Changeover - The process used to switch a

subscriber unit to another keyset so that the unused

keyset can be replaced without interrupting encrypted

communication.

Key Loader - Any type of device used to load encryp-

tion keys into a radio. With OTAR, this device must be

used to provide the initial key loading of a subscriber

unit so that it contains the basic keys needed for

OTAR by the KMF. If OTAR is not utilized, is always

used to load encryption keys. All keys stored in the

key loader are themselves encrypted. EFJohnson

offers a PDA-based keyloader.

Logical Link ID (LLID) - An ID transmitted with a

data message to identify the destination of the

message.

SECURE COMMUNICATION (ENCRYPTION)

Message Number Period (MNP) - The maximum

difference between message numbers that can occur

before a message is declared invalid (see Section

10.4.6).

Over-The-Air-Rekeying (OTAR) - The process of

sending new encryption keys over the air using an RF

interface.

Red - Refers to information that is not encrypted. The

opposite is “Black”.

Rekey - The process of preparing, sending, and

loading encryption keys into a subscriber unit for

current or future use. This may be done over-the-air

(OTAR) or by directly connecting a keyloader to the

subscriber unit.

Radio Set Identifier (RSI) - Subscriber units are

programmed with one or more Radio Set Identifier

(RSI) numbers that identify the unit for OTAR

purposes. The RSI can be unique to a individual

subscriber unit or unique to a group of subscriber

units. An individual (unit) RSI is always assigned and

one or more group RSIs may be assigned. The indi-

vidual RSI is typically programmed when the

subscriber unit is initially brought into service. The

KMF is also identified by an RSI (KMFRSI) to use as

the destination of any KMMs a subscriber unit origi-

nates. The KMMs (Key Management Messages)

generated by the KMF (Key Management Facility) are

addressed to a specific RSI.

Storage Location Number (SLN) - A link to a

specific key (TEK or KEK) in the active keyset. The

SLN specifies both a crypto group and a key within

the keysets in that crypto group (the first four bits of

the SLN are the crypto group ID). SLNs and CKRs are

equivalent terms (see Section 10.2).

Traffic Encryption Key (TEK) - A key used to

encrypt voice or data. The other type of key is the Key

Encryption Key (KEK) which is used to encrypt keys

contained in Key Management Messages. TEKs can

be either the AES or DES type.

Unique Key Encryption Key (UKEK) - A KEK

unique to a particular subscriber unit. Refer to “KEK”

for more information. These keys can be either the

AES or DES type.

Zeroize - The process of deleting all keys from a

compromised subscriber unit to disable it. To make the

unit functional again, the keys must be reloaded by a

keyloader.

10.5 RADIO SETUP FOR ENCRYPTION

10.5.1 GENERAL ENCRYPTION SETUP

The following radio setup is required for encryp-

tion regardless of whether OTAR is used:

Options Enabled - The desired encryption type must

have been enabled at the factory (DES, DES-XL,

DES-OFB, AES). To determine what options are

enabled, using the PCConfigure programming soft-

ware, select the Transfer > Read Options From Radio

menu parameter.

PCConfigure Programming

PID/SLN Mode - On the global screen, select

either the PID or SLN mode (see Section 10.2.3).

If the SLN mode is used, also program the Keys

Table by clicking the button.

Infinite Key Retention - On the global screen,

select this parameter to store keys permanently

in memory (see Section 10.2.4).

Erase Keys On Keyset Change - On the global

screen, if the SLN mode is selected and more

than one keyset is used (see Section 10.4.3),

select this parameter to erase keys when

changing keysets (see Section 10.2.6).

Program Channel/Group PIDs and Encryption

Type - With conventional analog calls, this infor-

mation is programmed on the channel screen.

With other types, it is programmed in the talk

group list selected on the system screen. In addi-

tion, with conventional digital calls, the group

programming can be overridden on the channel

screen (see Section 10.3.3). Additional PIDs for

special calls can also be specified on the system

screen for digital and trunked calls. NOTE: The

encryption type is not selectable on digital chan-

nels because the AES/DES mode is determined

by the key type loaded, not by PCConfigure

programming.

SECURE COMMUNICATION (ENCRYPTION)

Currently, EFJohnson 41xx portables and 43xx

mobiles that meet the following requirements support

OTAR:

Programming - An RSI and UKEK and other infor-

mation must be programmed as described in the next

section.

10.5.2 ADDITIONAL SETUP FOR OTAR

Additional PCConfigure Programming For OTAR

The following parameters must be programmed

for OTAR operation in addition to those in Section

10.5.1 .

1. On the Radio Wide Conventional screen, program

the Digital Unit and Unit RSI IDs. The Unit RSI

ID can be set to the Digital Unit ID only, but later

can be changed by the KMF or keyloader if desired.

Note these two numbers.

2. On the Per System Conventional screen, select

OTAR Enabled = On and Data Registration

Enabled = On. When data registration is enabled,

the radio registers with the data system on a channel

change.

3. Also on the Per System Conventional screen, set the

OTAR Time Out Time. When rekeying is

requested by the radio (OTAR Rekey option button

pressed or menu selected), this setting determines

how long the radio waits for a response from the

KMF. Times of 20-180 seconds can be programmed,

and the default is 30 seconds.

Motorola RNC Registration (If Required)

The 41xx portable does not support Motorola

dynamic data registration. Therefore, each radio must

be manually registered on the Motorola RNC Console

by entering the following command:

LCRD 03 06 00 1234 7F xx xx xx 0A 0A 00 07 00 yy

Where, “xx xx xx” is the hex value of the Digital

Unit ID entered by the PCConfigure software. Refer to

the console documentation for the value of “yy” or use

“00”. This registration needs to be done only once.

Programming By Keyloader

The following are the minimum parameters that

need to be programmed in the radio to perform OTAR.

It is not necessary to program a TEK to perform

OTAR. If the radio does not contain a TEK, the KMF

initiates a warm start-up sequence in which a tempo-

rary TEK is transferred to the radio to perform the key

transfer.

1. UKEK - This key normally has SLN (CKR) 61440

and Key ID 62880 (F5A0 hex). Create a key (either

AES or DES type as required) and download it to

the radio.

2. RSI - This is normally initially the same as the P25

Unit ID and is programmed by the PCConfigure

software as described in Section 10.5.1. Therefore,

the RSI should not need to be loaded if it is the first

time the radio is being set up for OTAR or if the

radio dumps keys due to long-term battery discon-

nect. However, it may need to be loaded if the radio

is manually deleted from the KMF and then recre-

ated since the message number must be reset to 0

(the Load Target RSI command resets the message

number to 0).

3. KMF RSI - This RSI is normally 9,999,999 and

should not need to be loaded since it defaults to this

number.

4. MNP (Message Number Period) - Load the proper

message number period into the radio (typically

1000). Refer to Section 10.4.6 for more information.

5. Verify that the above information was properly

stored in the radio by viewing it using the keyloader.

10.6 RADIO OTAR CAPABILITIES

10.6.1 SEM 4100/53XX, STANDARD 41XX

The OTAR capabilities of the SEM equipped

4100 portable and 4300 mobile are as follows.

Keysets

•Up to three keysets are used and it is assumed all

three are always present.Keyset IDs 1 and 2 are for

SECURE COMMUNICATION (ENCRYPTION)

TEKs and only one is active at a time. Keyset ID 255

is for KEKs and is considered active all the time

•Each keyset can have up to 128 keys. However, 16

or less are normally used.

•AES encryption is supported (with Flash code 1.8.0

or later) but not currently available with OTAR

(future availability is planned).

RSI (Radio Set Identifier)

•One individual RSI and it is usually initially the

same as the P25 Unit ID.

•One group RSI (usually initially “0”).

•One KMF RSI (usually always 9,999,999).

OTAR Messages That Are Supported

The following KMM Message IDs are recognized

by or sent:

CHANGE RSI 0x03

REKEY 0x1E

WARM START 0x20

ZEROIZE 0x21

ZEROIZE RESPONSE 0x22

10.6.2 UCM EQUIPPED 4100

The 41xx UCM version uses the Motorola UCM

encryption module. Therefore, the OTAR capabilities

are determined by that module. All capabilities of the

Motorola KVL and KMF are supported. Initial radio

programming by the PCConfigure software is the

same as described in

Section 10.5.

10.6.3 OTAR OPTION SWITCHES

The following additional option switches can be

programmed with the 4100 portable and 4300 mobile

to control OTAR functions. They are also available as

4100 menu parameters unless noted otherwise.

Change Keyset - Toggles the active keyset between

Keyset 1 and Keyset 2. The new active keyset is

briefly displayed and then normal operation resumes.

When the 4100 menu is used, the current active keyset

is indicated by an asterisk. To change to the other

keyset, highlight it and press the F2 key.

Clear/Secure Select - This enables and disables

encryption regardless of whether OTAR is used. Refer

to Section 10.3 for more information.

Erase Keys - Erases all TEK and KEK keys contained

in the radio. With the 4100, this function is available

as menu parameter only.

Key Select - This allows a different key to be selected

for the current channel or group (conventional chan-

nels only). Refer to Section 10.2.5 for more

information.

OTAR Rekey Request - Sends a message which tells

the KMF that the radio is on the air and requests

rekeying. The following status messages are displayed

which indicate the progress of this function. Addi-

tional functions that are available when this is selected

using the 4100 menu mode are described in the next

section.

Rekeying - A radio-initiated rekeying session is in

process.

No Ack - No response was received from the KMF

in response to an Identify request before time out

occurred (approximately 30 seconds).

Ack Rcvd - An acknowledgement was received in

response to an Identify request.

No Service - A “No Service” reply was received

from the KMF. No rekeying will take place.

SECURE COMMUNICATION (ENCRYPTION)

Rekey Fail - Either the rekey command failed or

timed out (after approximately 30 seconds). This

message could indicate that the rekey request

message was not received by the KMF. However,

depending on the KMF configuration and channel

traffic, it is possible that the message was received

and a response is still pending.

Rekeyed! - The rekey session initiated by the radio

was successful.

Additional Functions Selectable by 4100 Menu:

(To select one a parameter, highlight it and press

F2.)

Rekey - Performs the same function as the OTAR

Rekey Request option switch described in the

preceding section.

Need KEK - Sends a request for a new KEK (Key

Encryption Key). Upon receiving this message, the

KMF marks the radio as requiring service. One time

this function may be selected is if the radio dumps it

keys.

Identify - Sends a message which tells the KMF that

the radio is on the air. Currently, the KMF always

responds with “No Service”, even if the keys are not

up to date. If “No Ack” is displayed, the KMF may

not have received the message (see preceding

section). This function can be used to test communi-

cation without initiating the rekeying that occurs

with the preceding “Rekey” function.

Erase Keys - Erases all keys in the radio the same as

the Erase Keys option switch described in the

preceding section.
