GENERAL INFORMATION

SECTION 1 GENERAL INFORMATION

1.1 SCOPE OF MANUAL

This service manual contains alignment and

service information for the E.F. Johnson 5100-Series

portable digital transceivers.

1.2 TRANSCEIVER DESCRIPTION

1.2.1 GENERAL

The 5100-series portable digital transceivers have

multiple system select capability to allow operation in

various types of radio systems (see next sections).

Models are available for operation in the following

frequency range: 806-870 MHz.

Repeater talk-around, which allows transmitting

on the receive frequency, is also available

with all bands.

Power output is user switchable for low and high levels

as follows:

800 MHz - 3 watts only

1.2.2 ANALOG/DIGITAL OPERATION

The 5100-series transceivers use a digital signal

processor (DSP) to provide the signal modulation

required to operate on the following types of channels.

This provides backwards compatibility with existing

equipment and also the ability to operate on various

types of radio systems.

Wideband Analog - FM modulation is used with a

maximum deviation of 5 kHz. This mode is usually

used in systems where the channel spacing is 25 kHz

or 30 kHz.

Project 25 Digital - Operates on Project 25 compatible

systems. The voice is digitized, error corrected,

optionally encrypted, and then transmitted using

C4FM modulation according to the Project 25 stan-

dard. This mode uses a channel spacing of 12.5 kHz.

1.2.3 OPERATING PROTOCOLS

The 5100-series transceivers can be programmed

for all the following operating protocols. Refer to

Section 2 for more operation information.

•Conventional analog

•Conventional Project 25 (digital)

•Trunked Project 25 (digital)

•SMARTNET’/SmartZone® analog or Proj 25

(digital)

1.2.5 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 as used with this transceiver is a collec-

tion of channels (talk groups) belonging to the same

repeater site. A system defines all the parameters and

protocol definitions required to access a site. Up to

1 conventional system and 15 SMARTNET/

SmartZone systems can be programmed (16 total).

GENERAL INFORMATION

1-2 September 2001

Part No. 001-5100-001

Channels

A channel selects a radio channel or talk group in

a system 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, and other

parameters unique to that channel.

SMARTNET/SmartZone Operation - A channel

selects a specific talk group, announcement group,

emergency group, and other parameters unique to that

channel.

A maximum of up to 256 channels can be

programmed with the preceding modes. The conven-

tional system can be programmed with up to 256 chan-

nels, and each of the SMARTNET/SmartZone systems

can be programmed with up to 256 talk groups

(channels).

Therefore it is theoretically possible to program

any combination of these systems that produces up to

256 total channels. However, the maximum number

may be 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 systems increases. The programming

software displays a bar graph which shows the amount

of available memory space that is used by the current

data. Refer to Section 3.1.10 for more information.

Zones

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

type (conventional or SMARTNET/SmartZone). For

example, a zone could include 12 conventional chan-

nels and 4 SMARTNET channels. Zones are similar to

banks used in other E.F. Johnson transceivers. One use

of zones may be to program the channels used for

operation in a specific geographical area. Up to 16

zones can be programmed.

1.2.6 SECURE COMMUNICATION

Secure communication is available with all the

preceding protocols. The following types of encryp-

tion are available:

Conventional Analog and SMARTNET/SmartZone

Operation

•460 Scrambling (Transcrypt)

Conventional Project 25 Operation

•DES-OFB

1.2.7 PROGRAMMING

Transceiver programming is performed using a

PC-compatible computer and an E.F. Johnson 5100

series programming cable and PCTrunk™ program-

ming software (see Table 1-1). Programming is

described in Section 3.

1.2.8 ALIGNMENT

Transceiver alignment is performed using the

same computer and cable used for programming (see

preceding section). In addition, special PCTune™

software, the Radio Interface Box (RIB), and a

computer cable are required. All adjustments are made

using the software (no manual adjustments are

required). Refer to Section 5 for alignment

information.

Repair service is normally available through local

authorized E.F. Johnson Land Mobile Radio Service

Centers. If local service is not available, the equipment

can be returned to the factory for repair. However, it is

recommended that you contact the Customer Service

Department before returning equipment because a

service representative may be able to suggest a solu-

tion to the problem so that return of the equipment

would not be necessary.

Be sure to fill out a Factory Repair Request Form

#271 for each unit to be repaired, whether it is in or

out of warranty. These forms are available free of

charge by calling Customer Service (see Section 1.7)

or by requesting them when you send a unit in for

repair. Clearly describe the difficulty experienced in

the space provided and also note any prior physical

damage to the equipment. Then include a form in the

shipping container with each unit. Your telephone

number and contact name are important because there

are times when the technicians have specific questions

that need to be answered in order to completely iden-

tify and repair a problem.

2.4 GENERAL OPERATION

2.4.1 INTRODUCTION

The following section describes features available

with both trunked and conventional operation.

Features unique to conventional channels are

described in Section 2.6, and features unique to

SMARTNET/SmartZone channels are described in

Section 2.7.

2.4.2 TURNING POWER ON AND SETTING

VOLUME

Power is turned on and off by the On-Off/Volume

switch on the top panel. When power is initially turned

on, an alert tone sounds and the indicator on the top

panel flashes green. If a SMARTNET/SmartZone

channel is selected, the zone alias is then displayed

followed by the unit ID (see Section 2.7.2). The

selected channel is then indicated.

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

counterclockwise until a click occurs. The display may

remain on for a few seconds after power is turned off.

It is recommended that power not be turned back on

again until the display is blank.

The relative volume level can be determined by

noting the position of the index on the On-Off/Volume

knob. To enable a reference tone for setting the

volume, proceed as follows:

•If key press tones are enabled (see Section 2.4.11), a

short tone sounds when front panel keys are pressed.

•If a conventional channel is selected and the

Monitor option switch is programmed (see Section

2.6.4), pressing that switch unsquelches/squelches

the receiver and either voice or background noise is

heard. If a SMARTNET/SmartZone channel is

selected, the receiver cannot be manually

unsquelched.

2.4.3 POWER-UP PASSWORD

General

The power-up password feature prevents unau-

thorized use of the transceiver. When it is enabled by

system operator programming, an eight-digit password

must be entered to make the transceiver operational

each time power is turned on. Passwords can be

entered even if the keypad is locked (see Section

2.4.6). The default password is eight zeros

(00000000). Refer to Section 3.7 for more informa-

tion on passwords.

If this feature is enabled, proceed as follows to

unlock the radio:

1. Turn radio power on and when “LOCKED” is dis-

played, enter the eight-digit numeric password

using the keypad. As each digit is entered, a dash is

displayed. If an incorrect digit is entered, press the

CLR key and re-enter the entire password.

2. When all eight digits have been entered, press the

ENT key. If the password is correct, the display

indicates normal zone and then channel informa-

tion. If an incorrect password is entered,

“LOCKED” is again displayed.

Changing Password

The current password can be changed as follows:

1. The locked mode must be selected to change the

password, so cycle power if necessary to display

“LOCKED”.

2. Enter the old eight-digit password and press the #

key (not ENT). If the correct password is entered,

“NEW PSWD” is displayed.

3. Enter the new password and press ENT. The pass-

word is changed.

2.4.4 BACKLIGHT

The backlight for the display and keypad can be

manually turned on by pressing the Backlight option

switch if it is available. The backlight can also be

system operator programmed to automatically turn on

The programmable option switches are as

follows:

•F1, F2, F3, and F4 on front panel. In addition, with

full keypad (18-key) models, the # key is program-

mable (see Figure 2-1).

•The two push-button switches on the side panel (see

illustration in Section 2.3.3).

•The 3-position toggle switch on the top panel (see

Figure 2-2).

If your radio is programmed with both conven-

tional and SMARTNET/SmartZone channels (see

Section 2.4.12), these option switches can be system

operator programmed to control a different set of func-

tions for each channel type. For example, the F1

switch could select Hi/Lo Power when a conventional

channel is selected and Private Calls when a

SMARTNET/SmartZone channel is selected. The

available functions in each mode are indicated in the

tables in Section 2.2. If no option switch has been

programmed to control a particular function, that func-

tion may not be available or may be in a fixed mode.

2.4.6 KEYPAD LOCK

If the Keypad Lock option switch has been

programmed, the keypad can be locked (disabled) to

prevent keys from being accidentally pressed. To lock

the keypad, simply press this switch. Then to unlock it

again, press and hold it until a tone sounds. The

keypad can also be disabled by system operator

programming. It is then permanently disabled and

cannot be re-enabled by the user.

2.4.7 LOW BATTERY INDICATION

When the battery voltage falls below a preset

level, the radio can be programmed so that any or all

of the following indications occur:

•The indicator on the top panel flashes red in the

transmit mode and green in the receive mode.

•A chirp sounds every 5 seconds in the receive mode.

•A chirp sounds every 5 seconds in the transmit

mode.

The battery should be recharged as soon as prac-

tical after a low battery indication appears.

2.4.8 CHANNEL AND ZONE SELECTION

Channel Select

To change the current channel, rotate the 16-

position channel selector knob on the top panel to the

desired position. With SMARTNET/SmartZone chan-

nels, the selected channel is always indicated by an

alias (name). The alias is also displayed with conven-

tional channels if the Display Mode option switch is

not programmed. If this switch is programmed, the

channel number or frequency may also be displayed

(see Section 2.6.2).

Zone Select

A zone is a group of up to any 16 conventional

and SMARTNET/SmartZone channels defined by

system operator programming. Up to 16 zones can be

programmed for a total of 16 x 16 channels per zone or

256 channels. One use of zones may be to select

groups of channels programmed for operation in

different geographical areas or radio systems. If select-

able zones have been programmed in your radio,

consult your system operator for more information on

how they are used. Zones are selected as follows:

1. Press the Zone option switch and the alias (name) of

the current zone is flashed in the display.

2. Use the number keys to enter the desired zone

number or scroll through the available zones using

the and keys.

3. When the desired zone is displayed or entered,

select it by pressing the ENT key or waiting 4

seconds.

OPERATION

2-7 September 2001

Part No. 001-5100-001

2.4.9 HOME ZONE

The radio can be programmed with a home zone.

Then when power is turned on, the radio can be

programmed so that either the home or last selected

zone is automatically selected.

If the Home Zone option switch is programmed,

it can be used to quickly select or change the home

zone. To select the home zone, simply press this

switch. To change the home zone to the currently

selected zone, press and hold this switch until a tone

sounds (approximately 1 second).

2.4.10 TIME-OUT TIMER

The time-out timer disables the transmitter if it is

keyed for longer than the programmed time. It can be

programmed on each channel for times of 15 - 225

seconds or it can be disabled (not used). If the trans-

mitter is keyed continuously for longer than the

programmed time, the transmitter is disabled and an

invalid condition tone sounds. Five seconds before

time-out occurs, an alert tone sounds to indicate that

time-out is approaching. The timer and tone are reset

by releasing the PTT switch.

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. Conventional channels can

also be programmed with the Penalty and Conversa-

tion timers that are described in Sections 2.6.7 and

2.6.8.

2.4.11 TONE ENABLE/DISABLE

The supervisory tones (see Section 2.8) can be

enabled and disabled by the Tones On-Off option

switch if it is programmed. When tones are enabled by

this switch, “TONE ON” is momentarily displayed

and a tone sounds. Conversely, when tones are

disabled, “TONE OFF” is displayed and no tone

sounds. If the Tones On-Off option switch is not

programmed, tones are fixed in the on or off mode by

programming.

2.4.12 TRANSCEIVER OPERATING MODES

Introduction

Each selectable channel can be programmed for

either the conventional or SMARTNET/SmartZone

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.

Conventional Mode

This is a non-trunked operating mode which

accesses independent radio channels (there is no auto-

matic access to several channels). Monitoring before

transmitting may not be automatic in this mode, so you

may need to manually monitor the channel before

transmitting to make sure that it is not in use. Either

analog or digital (Project 25) signaling may be used.

When a digital channel is selected, “DIG” is indicated

in the upper part of the display. Channel monitoring

and other operating features unique to conventional

channels are described starting with Section 2.6.1.

SMARTNET™/SmartZone® Mode

This is a trunked operating mode that uses ID

codes to select what mobiles are being called and what

calls are received. Monitoring is performed automati-

cally and special messages and tones indicate busy and

out-of-range conditions. Enhanced features include

roaming (SmartZone only), telephone, private, and

emergency calls, Call Alert™, and messaging. Either

analog or digital signaling may be used. When a

digital channel is selected, “Dig” is indicated in the

upper part of the display. Operating features unique to

SMARTNET/SmartZone channels are described

starting with Section 2.7.1.

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 and

attempts to register on the radio system. Once a

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

selected channel is displayed. If a control channel

could not be found (because of an out of range condi-

tion or the system ID is not correct, for example), “NO

SYS” is displayed and the radio continues to search

for a control channel.

OPERATION

2-8 September 2001

Part No. 001-5100-001

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.

2.4.13 SECURE COMMUNICATION

This transceiver may be optionally equipped to

provide secure communication on some or all chan-

nels. This feature encrypts your voice so that it can be

understood only by someone using a transceiver

equipped with a similar encryption device and encryp-

tion codes.

When a secure call is received or transmitted,

“Sec” is indicated in the upper part of the display.

Secure communication can be programmed on a per

channel basis to operate in various ways. If equipped

with the Clear/Secure option switch and the current

channel is programmed to allow switch selection,

secure communication can be manually enabled and

disabled by that switch. Secure communication can be

programmed on a per channel basis to operate in

various ways. Refer to Sections 2.6.17 and 2.7.15 for

more information.

2.5 SCANNING

2.5.1 INTRODUCTION

Scanning cycles through a list of channels called

a “scan list”, checking each for messages. When a

message is detected that your transceiver is

programmed to receive, scanning stops and the

message is received. Shortly after the message is

complete, scanning resumes (unless it has been

disabled).

There are two basic scan modes: Standard and

Radio Wide. The Standard mode is unique to the type

of channel selected (conventional or SMARTNET/

SmartZone), and the Radio Wide mode is the same

regardless of the channel type selected. Only one of

these scan modes can be enabled at a time. Therefore,

if standard scanning is enabled while radio wide scan-

ning is occurring, radio wide scanning is automatically

disabled and vice versa. More information on these

modes follows.

2.5.2 STANDARD SCANNING

Standard scanning monitors only channels that

are the same type as that currently selected. There-

fore, if a conventional channel is selected, only

conventional channels are scanned, and if a

SMARTNET channel is selected, only SMARTNET

channels are scanned. Standard scanning is turned on

and off by the Scan option switch as follows. If this

switch is not programmed, standard scanning is not

available.

•To turn standard scanning on, press the Scan option

switch. Scanning is enabled when the “Scan” icon

is indicated in the upper right corner of the front

panel display and “SCAN ON” is briefly displayed.

•To turn scanning off, press the Scan option switch

again. The “Scan” icon is then no longer indicated

and “SCAN OFF” is briefly displayed.

•If the zone or channel is changed while scanning is

selected, scanning continues on the same or a

different scan list (see scan list information which

follows).

2.5.3 RADIO WIDE SCANNING

Radio wide scanning monitors the channels in the

preprogrammed radio wide scan list (see Section

2.5.5). This list may contain up to 16 channels of any

type (conventional or SMARTNET/SmartZone)

assigned to any zone. Radio wide scanning is turned

on and off by the Radio Wide Scan option switch as

follows. If this switch is not programmed, radio wide

scanning is not available.

•To turn radio wide scanning on, press the Radio

Wide Scan option switch. Scanning is enabled when

“Scan” is indicated in the upper right corner of the

front panel display and “SCAN ON” is briefly

displayed.

•To turn radio wide scanning off, press the Radio

Wide Scan option switch again. The “Scan” icon is

then no longer indicated and “SCAN OFF” is briefly

displayed.

OPERATION

2-9 September 2001

Part No. 001-5100-001

•If the zone or channel is changed while radio wide

scanning, scanning continues normally.

2.5.4 SCAN RESUME DELAY

When a message is received or transmitted while

scanning, there is a system operator programmable

delay before scanning resumes. The delay after

receiving a call prevents another message from being

received before you can make a response, and the

delay after transmitting a call ensures that you hear a

response to your call instead of another message

occurring on some other channel.

2.5.5 STANDARD MODE SCAN LIST

NOTE: The selected channel is always scanned.

With conventional operation, up to three scan lists

can be programmed. The list that is scanned is selected

by the Scan option switch as described in Section

2.6.12. Selecting another conventional channel does

not change the current scan list. The scan lists are user

programmable if the Scan Edit option switch is

programmed (see Section 2.5.9).

With SMARTNET/SmartZone operation, each

channel can be programmed so that one of up to three

different scan lists is automatically selected or scan-

ning is disabled. The scan list assigned to the current

channel is not user selectable, but it is user program-

mable if the Scan Edit option switch is programmed

(see Section 2.5.9).

2.5.6 RADIO WIDE MODE SCAN LIST

With radio wide scanning, there is only one

preprogrammed scan list available regardless of the

type of channel selected, and it is not user

programmable.

2.5.7 DETERMINING WHICH CHANNELS ARE

IN SCAN LIST

Channels in the standard SMARTNET/Smart-

Zone and radio wide lists are not indicated. With

conventional channels, the selected channel is in the

current scan list if “SL” (Scan List) is indicated in the

upper part of the display.

2.5.8 NUISANCE CHANNEL DELETE

With standard scanning, channels can be tempo-

rarily deleted from the scan list, for example, if

messages on a channel become annoying. This feature

is not available with radio wide scanning. Proceed as

follows:

NOTE: The selected channel and conventional priority

channels 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

the alert 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 events occur:

•Scanning is turned off and then on again using the

Scan switch.

•Transceiver power is turned off and then on again.

•The scan list is reselected by pressing the number

key corresponding to the list number (conven-

tional) or by selecting another channel

(SMARTNET/SmartZone).

•Another channel is selected by the top panel

channel switch.

2.5.9 PROGRAMMING A SCAN LIST

When full keypad (18-key) models, conventional

and SMARTNET/SmartZone standard scan lists are

user programmable if the Scan Edit option switch is

programmed and user programming of the list is

allowed. Scan list programming is not available with

limited keypad (6-key) models. Proceed as follows to

program a scan list:

Preliminary

1. With conventional channels, select the list to be

edited (1-3) by pressing the key corresponding to

the desired list number with scanning enabled (see

Section 2.6.12). If a list is not selected, the last

active scan list is automatically edited. With

SMARTNET/SmartZone channels, the scan list for

OPERATION

2-10 September 2001

Part No. 001-5100-001

the selected channel is fixed and cannot be changed.

Scanning may also be disabled on some channels.

2. If scanning is enabled, turn it off by pressing the

Scan option switch.

3. Press the Scan Edit option switch. The alias of the

first channel in the scan list is displayed. If scan list

programming or scanning is disabled on the selected

list or channel, “NO LIST” is momentarily

displayed and scan list programming is not avail-

able. Proceed as follows to delete or add a channel:

To Delete a Channel:

4. Select the channel you want to delete by pressing the

and keys.

5. With conventional channels, to delete the displayed

channel and exit this mode, press the CLR (F3) key.

With SMARTNET/SmartZone channels, press the

“2” key and then ENT (F4).

NOTE: The priority channel cannot be deleted (see

Section 2.6.13).

To Add a Channel:

1. Press the Scan Edit option switch. The alias of the

first channel in the scan list is displayed.

2. Enter the two-digit zone and channel number of the

channel you want to add. For example, to add Zone

1/Channel 5, enter “0105”. Refer to Section 2.4.8

for more information on zones and channels.

3. With conventional channels, to add the channel to

the scan list and exit this mode, press the ENT (F4).

With SMARTNET/SmartZone channels, press the

“1” key and then ENT (F4).

2.6 CONVENTIONAL FEATURES

2.6.1 INTRODUCTION

The following information describes features

unique to the conventional operating mode (see brief

description in Section 2.4.12). Refer to Section 2.4 for

information on features common to all operating

modes, and to Section 2.7 for information on features

unique to the SMARTNET/SmartZone mode.

2.6.2 DISPLAY MODE SELECTION

If the Displayed Information option switch is

programmed, it is usually the three-position toggle

switch on the top panel. This switch selects the

following conventional channel display modes. If this

switch is not programmed or a SMARTNET/Smart-

Zone channel is selected, the Alias mode is always

used.

Alias - The preprogrammed alphanumeric tag for the

channel is displayed.

Number - The channel number from 1-16 is displayed

as “CHAN xx”.

Frequency - The frequency of the selected channel is

displayed in megahertz. The transmit frequency is

displayed in the transmit mode and the receive

frequency is displayed in the receive mode.

NOTE: The channel number can also be determined

by noting the number (1-16) indicated by the index on

the channel selector knob.

2.6.3 MONITORING BEFORE TRANSMITTING

With conventional operation, you may need to

manually monitor the channel before transmitting to

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

you were to transmit while someone else was using the

channel, you would probably disrupt their conversa-

tion. Channels are monitored automatically or manu-

ally as follows:

Automatic Channel Monitoring

If the selected channel is programmed for Busy

Channel Lockout feature (consult your system oper-

ator), monitoring is performed automatically. Refer to

the description of this feature in Section 2.6.5 for more

information.

Manual Channel Monitoring

The automatic monitoring just described may not

be programmed or it may occasionally disable the

OPERATION

2-11 September 2001

Part No. 001-5100-001

transmitter even if the channel is not in use. In this

case, the channel must be monitored manually as

follows:

Rx Indicator - With scanning disabled, note if the indi-

cator on the top panel is steady green. If it is not, the

channel is not being used and you can transmit your

call. If it is green, the channel may be busy and you

should not place your call (see next paragraph).

Monitor Mode - There may be times when the busy

indication is displayed even though no one is using the

channel. Monitoring should then be performed by

disabling Call Guard squelch using the Normal/Selec-

tive option switch as described in Section 2.6.6 or the

monitor mode described next.

2.6.4 MONITOR MODE

The monitor mode temporarily disables squelch

control features (such as Call Guard® squelch) so that

all messages are heard on the selected channel. It also

overrides the Busy Channel Lockout feature (see next

section) and temporarily halts scanning.

To monitor the selected channel, select the

monitor mode by briefly pressing or pressing and

holding the Monitor option switch (if available). The

receiver unsquelches and a rushing noise or voice is

heard when the monitor mode is enabled. To disable

the monitor mode and return to normal operation,

release the Monitor switch or press it a second time.

If scanning is enabled, pressing and holding the

Monitor option switch monitors the current scanned

channel instead of the selected channel if applicable.

2.6.5 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 a busy condition is detected by this

feature, the transmitter is disabled, “BUSY” is indi-

cated in the display, and a tone similar to a standard

telephone busy tone sounds until the PTT switch is

released. The transceiver can be programmed to

operate in one of the following modes on each

channel:

Off - Busy channel lockout is disabled and the trans-

mitter keys even if the channel is busy.

Noise - The transmitter is disabled if a carrier is

detected on the channel.

Tone - The transmitter is disabled if an incorrect Call

Guard (CTCSS/DCS) or NAC code is detected (see

Section 2.6.6). An incorrect code is any code other

than the one programmed for the current channel.

If busy 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.

2.6.6 CALL GUARD SQUELCH

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 transceiver to be

functional.

Call Guard Squelch Enable/Disable

To disable Call Guard (Selective) squelch so that

all messages on the selected or scanned channels are

heard, press the Normal/Selective option switch (if

available) so that “NORMAL is flashed in the display.

Then to re-enable Call Guard squelch, press the

Normal/Selective switch again so that “SELECTIV” is

flashed. The mode selected by this switch does not

change when other channels are selected or power is

cycled. Call Guard squelch can also be disabled by the

monitor mode described in Section 2.6.4.

OPERATION

2-12 September 2001

Part No. 001-5100-001

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

transceiver. Both the transmitting and receiving trans-

ceiver must be equipped with this feature for it to be

utilized.

Digital Call Guard Squelch

Digital Call Guard squelch (CDCSS) 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

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

valid code was received.

Keypad Selectable Call Guard Code (CTCSS/DCS)

If you have the full keypad (18-key) model and

the ability to change Call Guard codes has been

enabled by programming, the transmit and receive

codes from one channel can be temporarily or perma-

nently reassigned to all channels of the current zone.

Proceed as follows:

1. Using the number keys, enter the number of the

channel that is programmed with the code you want

to reassign to all channels (only channels 1-9 can be

selected). See Section 2.6.2 for information on

displaying channel numbers.

2. The display then briefly indicates “CODE x”, where

“x” is the key you pressed. The codes assigned to

that channel are then reassigned to all the other

channels in the current zone. The reassignments

remain in effect even after power is cycled.

3. To restore all Call Guard codes in the current zone

to the original settings, press the “0” key.

NOTE: Keypad programming described in Section 2.9

can be used to change the Call Guard code of indi-

vidual channels.

2.6.7 PENALTY TIMER

A penalty timer may be programmed on conven-

tional channels to prevent transmissions for 15 - 225

seconds after the time-out timer described in Section

2.4.10 disables the transmitter. The penalty timer starts

when the PTT switch is released after the transmitter

has been disabled. If the PTT switch is pressed during

the penalty time, the time-out indication occurs again.

A beep sounds when the penalty timer expires and the

transmitter can then be keyed.

2.6.8 CONVERSATION TIMER

A conversation timer can be programmed on

conventional channels to limit the total length of a

conversation rather than just the length of each trans-

mission as with the time-out timer. This timer can be

programmed for 0.5 - 7.5 minutes, and it is reset when

the time between transmissions exceeds the penalty

time just described. A warning tone sounds 5 seconds

before the conversation timer expires. When it expires,

the transmitter is disabled and a warning tone sounds.

The transmitter remains disabled for the length of the

penalty time, and a beep sounds when it can be keyed

again.

2.6.9 REPEATER TALK-AROUND

Normally, all your transmissions go through a

repeater which usually increases range. However, if

OPERATION

2-13 September 2001

Part No. 001-5100-001

you are out of range of the repeater, you cannot talk to

anyone else on that channel even though the mobile

you are calling may be only a short distance away. To

allow communication when this situation occurs,

repeater talk-around can be used to allow direct

communication with a mobile without going through a

repeater.

Repeater talk-around can be selected if the

Repeater Talk-Around option switch (if available).

When talk-around is enabled by this switch, “RTA

ON” is flashed in the display. Then when it is disabled

by pressing the switch again, “RTA OFF” is flashed.

Changing channels or turning power off does not

change the selected talk-around mode.

2.6.10 POWER OUTPUT SELECT

If the High/Low Power option switch is

programmed and power selection is permitted on the

current channel, either high or low transmitter power

can be selected. Generally, the high power setting

allows you to transmit longer distances but uses more

battery power, and the opposite occurs with the low

power setting.

Pressing the High/Low Power switch toggles the

power setting. The new level is flashed in the display

when this switch is pressed as “HI POWER” or “LO

POWER”. If power selection is not permitted on the

channel, the fixed power level is flashed and no power

change occurs. Turning power off or changing chan-

nels does not change the power setting selected for a

channel. Selectable power is not available with 800

MHz models.

2.6.11 EMERGENCY MODE (CONVENTIONAL)

On conventional channels, an emergency mode

may be programmed to be selectable by the Emer-

gency switch located next to the antenna (see illustra-

tion in Section 2.3.2). Scanning is automatically

disabled in the emergency mode, so transmissions

occur on the selected channel.

If an analog channel is selected and scrambling is

programmed, pressing the Emergency switch sends an

emergency signal on the selected channel 20 times or

until an acknowledgment is received. Keying the radio

also cancels the emergency condition.

If a Project 25 (digital) channel is selected,

pressing this switch selects the emergency mode and if

the PTT switch is pressed, an emergency status is sent.

Radio power must be turned off to cancel the emer-

gency mode on a Project 25 channel.

2.6.12 CONVENTIONAL MODE SCANNING

General

The following information describes scanning

features unique to conventional operation. Scan opera-

tion common to all modes is described in Section 2.5,

and scan operation unique to SMARTNET/

SmartZone operation is described in Section 2.7.12.

Selecting a Scan List

With full keypad (18-key) models, one of up to

three scan lists can be selected when scanning with a

conventional channel selected. These lists can be

system operator or user programmed as described in

the information which follows. With limited keypad

(6-key) models, only one scan list is available and it

cannot be user programmed. However, nuisance chan-

nels can still be temporarily deleted as described on

Section 2.5.8.

Proceed as follows to select a scan list with full

keypad models:

1. If required, enable scanning by pressing the Scan

option switch.

2. To select a list, press the number key corresponding

to the number of the desired list (1-3). The selected

list is then briefly displayed as “Scan x” where “x”

is the list number. The selected scan list is stored in

memory and does not change until this procedure is

repeated.

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.

OPERATION

2-14 September 2001

Part No. 001-5100-001

No Priority - No priority channel sampling occurs

when the list is selected. The radio transmits on the

selected channel.

Priority/Tx Priority - Priority sampling occurs and

the priority channel is the one programmed in the

selected scan list. The radio transmits on the priority

channel.

Priority/Tx Selected - Priority sampling occurs and

the priority channel is the one programmed in the

selected scan list. The radio transmits on the selected

channel.

Priority on Selected - The priority channel is always

the selected channel. The radio transmits on the

selected channel.

Talk ba c k - 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.

2.6.13 PRIORITY CHANNEL SAMPLING

General

The priority channel sampling feature ensures

that when standard scanning is occurring, messages on

the priority channel are not missed while listening to a

message on some other channel. Your transceiver can

be programmed so that the priority channel is a fixed

channel associated with the current scan list, the

currently selected channel, or not used. When the

selected channel is a priority channel, “Pri” is indi-

cated in the upper part of the display.

Priority channel sampling occurs only with Stan-

dard conventional scanning. It does not occur with

Radio Wide scanning, when listening to any type of

SMARTNET/SmartZone call, or when transmitting. A

series of “ticks” may be heard and the indicator on the

top panel flashes green when the priority channel is

sampled while listening to a message on some other

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.

Changing The Priority Channel

If a specific priority channel is associated with

the current scan list, it can be changed if the Priority

option switch is programmed. Proceed as follows:

1. Select the scan list number to be edited as described

in Section 2.6.12. If a list is not selected, the last

active scan list is automatically edited.

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

ning are off (“Scan” is not indicated in display).

2. Select the channel that you want to be the priority

channel using the channel selector switch on the top

panel. If the channel is in a different zone, also select

the appropriate zone.

3. Press the Priority option switch and the “Pri” is

displayed to indicate that the selected channel is

now the priority channel.

2.6.14 PLACING AND RECEIVING STANDARD

CONVENTIONAL CALLS

Standard conventional calls are calls to or from

other mobile units on the selected channel. The proper

coded Call Guard signaling (see Section 2.6.6) may

need to be transmitted for them to receive your call

and also for you to receive their calls. Proceed as

follows to place and receive these calls:

Placing a Standard Conventional Call

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

Section 2.4.2. Select the channel programmed for

the mobile you want to call (see Section 2.4.8).

2. Monitor the channel automatically or manually as

described in Section 2.6.3.

3. Press the PTT switch and the call proceeds as

follows:

•If the Busy Channel Lockout feature is programmed

on the channel, the transmitter is automatically

disabled if the channel is busy (see Section 2.6.5).

•Otherwise, busy and out-of-range conditions are not

indicated and speaking can begin after monitoring

the channel as described in Section 2.6.3.

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 2.5 and 2.6.12

for more scanning information).

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

talk and release it to listen. If scanning, you may

have to respond before scanning resumes to ensure

that the response occurs on the channel of the call.

2.6.15 DTMF/ANI SIGNALING

DTMF (Dual Tone Multi-Frequency) tones can

be generated manually or automatically for ANI

(Automatic Number Identification) and other

purposes. The following options may be enabled by

system operator programming for each conventional

channel:

DTMF Keypad - Pressing 0-9, *, or # on the keypad

while holding the PTT switch transmits the corre-

sponding tone until the key is released.

Pre-Tx ANI - A preprogrammed ANI sequence is

automatically sent when you press the PTT switch.

Post-TX ANI - A preprogrammed ANI sequence is

automatically sent each time you release the PTT

switch.

Disabled - All DTMF signaling is disabled.

2.6.16 PROJECT 25 MODE FEATURES

Individual, Group, and NAC Codes

Individual ID - Each transceiver that operates on

Project 25 (digital) channels is programmed with

an 8-digit individual ID. This ID is unique for

each transceiver and can be any number from

1-16777216. When power is turned on with a

Project 25 channel selected, this ID is briefly

displayed.

Group ID - Each Project 25 channel is programmed

with a group ID that determines which group of

mobiles will receive the call. A call is received if

any Project 25 channel is programmed with that

group and the correct NAC is detected (see

following description). Group IDs can be any

number from 0-4095.

NAC - Project 25 conventional channels use a NAC

(Network Access Code) instead of Call Guard

squelch coding (see Section 2.6.6) 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 monitoring before trans-

mitting, is similar to that of standard analog

channels.

To receive a Project 25 group call, the talk group

programmed with the group ID being transmitted must

be selected or scanned. In addition, the receive NAC

programmed for that channel must be detected.

Viewing Individual ID

Each transceiver which operates on Project 25

(digital) channels is assigned an eight-digit individual

ID. When power is turned on with a Project 25 channel

selected, the individual ID of your radio is briefly

displayed.

Changing Talk Group Assigned To A Channel

If the Talk Group Select option switch is

programmed and user talk group programming is

permitted on the channel, the talk group assigned to a

channel can be changed. This change is permanent

OPERATION

2-16 September 2001

Part No. 001-5100-001

(cycling power does not reselect the old talk group).

Proceed as follows:

1. Select the channel to be changed and then press the

Talk Group Select option switch.

2. Display the talk group to be assigned to that channel

by pressing the and keys. Talk groups are

indicated by an alias (unique alphanumeric identifi-

cation).

3. To select that talk group and return to normal oper-

ation, press the Talk Group select switch again. If

talk group selection has been disabled on the chan-

nel by programming, the talk group does not change

and an error tone sounds.

Individual Calls

If the Individual Call option switch is

programmed and the radio is a full keypad (18-key)

mode, individual calls can be placed to a specific

mobile radio on Project 25 channels. This call differs

from standard group calls in that only one mobile

instead of entire groups of mobiles may receive the

call. To respond to an individual call, simply press the

PTT switch and begin talking before a call timer

expires. Proceed as follows to place this call:

1. Press the Individual Call option switch and the iden-

tification of the last individual call placed is dis-

played as IDxxxxxx.

2. If required, enter the ID of the mobile being called

using the keypad.

3. Press the PTT switch and begin talking.

When individual calls are received, the trans-

ceiver may be programmed to display the selected talk

group, the talk group of the call, or the ID of the

calling radio.

2.6.17 CONVENTIONAL SECURE

COMMUNICATION

Introduction

There are two different protocols that can be used

to provide secure communication on conventional

analog channels: SecureNet™ and 460 scrambling.

More information on these protocols follows.

SecureNet

SecureNet is a proprietary Motorola protocol that

digitizes the voice and then encrypts it using the DES

algorithm. It provides the highest level of security.

There are two DES protocols:

•DES (CFB) uses cipher feedback DES encryption.

A disadvantage of this type is reduced communica-

tion range when compared to clear voice.

•DES-XL uses counter addressing feedback DES. It

provides better range but at lower voice quality.

The transmission mode (DES or DES-XL) is

selected by the programming software for each

SecureNet analog channel. If a channel is programmed

for DES-XL, it will also receive DES, but transmis-

sions always occur in DES-XL.

Each SecureNet capable channel is assigned an

encryption number from 0-15. The key corresponding

to this number is loaded into the radio using the

Motorola key loader. There is a maximum of 16 keys

that can be loaded into the radio at one time.

Transmissions on an analog channel are in the

clear mode if the channel has been strapped to the

clear mode by programming, and in the SecureNet

mode if it has been strapped to SecureNet. If the

channel has been strapped to “switched”, the mode is

selected by the Clear/Secure option switch. When a

message is received or transmitted in the secure mode,

“Sec” is indicated in the upper part of the display.

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.

460 Scrambling

The 460 Scrambling protocol is a proprietary

Transcrypt protocol that is compatible with the stand-

alone scrambling option from Transcrypt. If equipped

OPERATION

2-17 September 2001

Part No. 001-5100-001

with the 460 Scrambler, a Clear/Secure option switch

may be programmed. Pressing this switch changes the

transmission mode for the selected channel and

momentarily displays either “CLEAR” or “SECURE”.

In the coded mode, transmissions are in scram-

bled voice on any 460-enabled channel and the mobile

receiving the call automatically responds in the scram-

bled mode because the receiver automatically switches

between the clear and coded modes.

Although 16 generic codes are loaded, only one is

active and all 460-enabled channels use this code. The

460 scrambling option also provides several other

signaling enhancements including Digital ID, Auto-

matic Status and Location Update, Individual and

Group ID calling, and Emergency.

Transmit Mode Options

Either the SecureNet or 460 protocol can be

selected, and then the following transmit options are

available for each:

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 2.5.4), it

occurs in the secure mode.

Coded - All calls are made in the selected secure

mode.

Switched - The mode is selected by the Clear/Secure

switch. With 460 scrambling, if responding to a secure

call, the secure mode is automatically selected if the

response occurs within the delay time. When the clear

mode is selected by this switch, “CLEAR” is flashed,

and when the secure mode is selected, “SECURE” is

flashed.

Receive Mode Options

With 460 scrambling, clear and scrambled signals

are always autodetected. In addition, the user can

switch between the clear and secure mode at any time

using the Clear/Secure option switch. SecureNet

signals are unintelligible when 460 scrambling is used

and vice versa.

With the SecureNet protocol, the following

receive options can be programmed:

No Autodetect - Only signals coded like the transmit

signals are received.

Secure Autodetect - Both clear and SecureNet signals

are automatically detected. This mode is automati-

cally selected if the transmit mode is switch selectable.

Proper Key Autodetect - An incoming Securenet call

is compared against all of the available keys

programmed into the radio. If a match is found, the

call is decrypted using matched key.

Project 25 (Digital) Channels

Project 25 digital channels use the DES-OFB

protocol. Using this protocol on digital channels does

not result in the degraded range that occurs with

analog channels. The same transmit mode options are

available as with the preceding analog operation. In

the receive mode, clear and secure messages are

always automatically detected.

2.7 SMARTNET/SMARTZONE FEATURES

2.7.1 INTRODUCTION

The following information describes features

unique to the SMARTNET and SmartZone operating

mode (see brief description in Section ). Refer to

Section 2.4 for information on features common to all

operating modes, and to Section 2.4.12 for information

on conventional mode features.

2.7.2 VIEWING UNIT ID

Each radio in a SMARTNET system is identified

with a six-digit system ID and Unit ID. To display

these IDs, make sure that a SMARTNET channel is

selected and then turn power off and then on again.

The system ID is briefly displayed as SYxxxxxx

followed by the Unit ID as EDxxxxxx.

2.7.3 STANDARD GROUP CALLS

Standard group calls are between you and another

mobile, group of mobiles, or a control station (a radio

an invalid group ID, or group calls are not allowed,

“REJECT” is displayed and an alert tone sounds.

•If an attempt is made to select the secure mode and

there is no available secure channel, “NO SEC” is

flashed and the call continues in the clear mode.

•If an attempt is made to change from the secure to

the clear mode and this is not permitted, “SEC

ONLY” is displayed and the call continues in the

secure mode.

Receiving a Standard Call

When a SMARTNET/SmartZone group call is

received, the transceiver can be programmed to

display the Individual ID of the calling mobile and/or

the received talk group alias. The Individual ID is

briefly displayed when the call is received and the talk

group and channel alias are then alternately displayed

(if applicable).

3. Answering a page is the same as placing a private

call. Therefore, press the Private Call option switch

and follow the instructions for placing a private call

in Sections 2.7.4 or 2.7.5, whichever is applicable.

2.7.8 MESSAGING

The messaging feature allows preprogrammed

messages to be sent to your dispatcher. Up to 16

messages can be preprogrammed, and they are identi-

fied by a tag (alias). If a Message option switch is

programmed, messages are sent as follows:

1. Momentarily press the Message option switch. The

alias of the last message sent is displayed.

2. Enter the index of the desired message if you know

it or scroll through the list using the and keys

until you find the desired message. Press the CLR

key to cancel the message.

3. Press the PTT switch to send the message. When the

message is received and acknowledged by the

dispatcher, a signaling success tone (six beeps)

sounds and the display returns to the normal channel

indication. If there is no acknowledgment after 6

seconds, a tone sounds and “NO ACK” is displayed.

Press the CLR key to return to normal operation.

2.7.9 SENDING STATUS CONDITIONS

The status feature allows you to send your current

status to your dispatcher. Up to eight status conditions

can be preprogrammed, and they are identified by an

alias (name). If the Status option switch is

programmed, status conditions are sent as follows:

1. Momentarily press the Status option switch. The

alias of the last status sent is displayed.

2. To change the displayed status, enter the index of the

desired status if you know it or scroll through the list

using the and keys until you find the desired

status. Press the CLR key to cancel this function.

3. Press the PTT switch to send the status. When the

message is received and acknowledged by the

dispatcher, a signaling success tone (six beeps)

sounds and the display returns to the normal channel

indication. If there is no acknowledgment after 6

seconds, a tone sounds and “NO ACK” is displayed.

Press the CLR key to return to normal operation.

2.7.10 EMERGENCY ALARM AND

EMERGENCY CALL

Emergency alarms and emergency calls are sepa-

rate functions that can be individually programmed on

SMARTNET/SmartZone channels. The Emergency

switch is pressed to initiate these features. This switch

is the orange button located next to the antenna

connector.

An emergency alarm is a special data transmis-

sion to alert your dispatcher of an emergency situation,

and an emergency call is an urgent request for access

to a voice channel. The emergency alarm and call are

transmitted on the emergency talk group or announce-

ment group that has been preprogrammed by your

system operator on the currently selected channel.

Proceed as follows:

1. To transmit an emergency alarm, select a SMART-

NET/SmartZone channel that has that feature

enabled and then press the Emergency option

switch.

2. The emergency alarm is then transmitted and

“EMERGNCY” is indicated in the display for a

short time. Transmitting continues until an acknowl-

edgment is received (indicated by two beeps) or the

programmed number of attempts have occurred.

Silent operation may also be programmed in which

case no audio or visual indication of the alarm con-

dition occurs.

3. To transmit an emergency call, press the Emergency

option switch with a SMARTNET/SmartZone chan-

nel selected that has that feature enabled. Then man-

ually press the PTT switch and begin speaking as

OPERATION

2-24 September 2001

Part No. 001-5100-001

with a standard call. All calls that follow are then

emergency calls and they occur on the emergency

talk group.

4. To exit the emergency mode, power must be turned

off and then on again.

2.7.11 FAILSOFT OPERATION

If a failure occurs in the SMARTNET/Smart-

Zone system so that it cannot be used, the transceiver

automatically enters the failsoft mode. When this

mode is selected, the display alternately indicates

“FAILSOFT” and the alias of the selected channel.

When in the failsoft mode, operation is in the

conventional mode on a preprogrammed failsoft

channel. If a transmission is attempted before a failsoft

channel is located, a continuous tone sounds until the

PTT switch is released. When the radio system returns

to normal operation, this condition is automatically

detected and normal operation resumes.

2.7.12 SMARTNET/SMARTZONE SCANNING

Scanning on a SMARTNET/Smartzone channel

is similar to the standard and radio wide scanning

described in Section 2.5. Each channel can be

programmed with a different scan list that includes up

to 16 channels, one of which can be a priority channel.

These scan lists are user programmable if the Scan

Edit option switch is programmed, and nuisance chan-

nels can be temporarily deleted (see Section 2.5.8).

Scanning is enabled/disabled by the Scan option

switch. In addition, channels can be programmed so

that scanning automatically starts whenever the

channel is selected. Scanning is temporarily disabled

and “Scan” turns off if a channel is selected that has

scanning disabled. Then when a channel is selected

again that permits scanning, it is automatically

re-enabled.

In addition to calls on channels in the scan list,

pages, private calls, and telephone calls are received

while scanning. Messages on the priority channel are

received while listening to lower priority messages.

However, private and telephone calls are not inter-

rupted by calls on the priority channel.

When responding to messages in the scan mode,

programming determines if the response always

occurs on the talk group of the call or the selected talk

group (if they are different). Transmissions occurring

at other times always occur on the selected talk group.

2.7.13 DYNAMIC REGROUPING

The dynamic regrouping feature allows a

dispatcher to switch users to a dynamically defined

channel to receive an important message. Dynamic

regrouping operates as follows:

1. When this command is received, the alternating

dynamic regrouping tone sounds, the transceiver

automatically changes to the regrouping channel,

and the display alternately indicates “REGROUP”

and the alias of the selected channel. All transmit-

ting and receiving then occurs on this channel.

2. To reset all talk and announcement groups to normal

so that only the designated regrouping channel is on

the dynamic group, manually select the designated

regrouping channel if you know it. If this channel is

not selected or there is no designated regrouping

channel, all transmissions occur on the dynamically

assigned group regardless of which channel is

selected, and the regrouping tone sounds each time

the PTT switch is pressed.

3. When regrouping is canceled by the dispatcher,

transceiver operation returns to normal.

2.7.14 SMARTZONE FEATURES

Introduction

As described in Section , the SmartZone® mode

provides wide area coverage by allowing roaming

between SMARTNET and conventional sites. Smart-

Zone operation is the same as SMARTNET with the

following additional features.

Determining Current Site

To determine the current radio site, momentarily

press the Site Search option switch (if programmed). If

currently registered on a site, “SITE x” is displayed,

where “x” is the site number. The display then indi-

cates the RSSI (Receive Signal Strength Indicator)

OPERATION

Part No. 001-5100-001

value of the current site as “RSSI x” and then returns

to displaying the channel alias.

Searching For a New Site

To search for a new site, press the Site Search

option switch (if programmed) to toggle through the

available sites. “RSSI x” is displayed as just described

and the channel alias is then displayed.

Locking/Unlocking a Site

It is sometimes desirable to stay on the current

site regardless of signal level. To lock the radio on the

current site so that it does not search for another, press

the Site Lock option switch (if programmed). The

display then momentarily indicates “LOCK x” to indi-

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

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

again and “UNLOCK” is momentarily displayed.

When locked on a site, it is still possible to search

for a different site using the site search function

described in the preceding section. When a new site is

found, the radio is then locked on that site.

2.7.15 SMARTNET/SMARTZONE SECURE

COMMUNICATION

On analog SMARTNET/SmartZone channels,

either the SecureNet or 460 protocols can be selected.

Operation is similar to conventional channel secure

communication described in Section 2.6.17.

On digital SMARTNET/SmartZone channels,

only the DES-OFB protocol is available. Talk groups

can be strapped to Clear, Coded, or Switch selectable,

and clear and secure messages are always

autodetected.

The following calls require their own encryption

key selection: emergency, failsoft, patch, telephone,

private, and system-wide.

2.9 KEYPAD PROGRAMMING

2.9.1 INTRODUCTION

Keypad programming is available with full

keypad (18-key) models if the Keypad Programming

option switch is programmed. It is then selected by

pressing this switch and entering the programming

password. This password is a series of eight digits

selected preprogrammed using PCTrunk, and it

prevents unauthorized changing of radio program-

ming. The default password is eight zeros, and the

ENT (F4) key must be pressed after the digits are

entered. This password is not user reprogrammable.

Keypad programming allows conventional

channel parameters such as the transmit and receive

frequency and Call Guard squelch code to be changed.

In addition, several conventional mode timers can be

programmed. It cannot be used to reprogram disabled

or SMARTNET/SmartZone channels.

2.9.2 MENU STRUCTURE
