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.
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.
NOTICE: This radio is intended for use in occupational/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.
COMPLIANCE WITH RF EXPOSURE
STANDARDS
Your EFJohnson two-way radio is designed and
tested to comply with a number of national and international 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 environment 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.
Experts in science, engineering, medicine, health
and industry work with organizations to develop standards 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 exposure levels. In addition, manufacturers also recommend specific operating instructions to users of twoway radios. These instructions are important because
they inform users about RF energy exposure and
provide simple procedures on how to control it. Please

Operating Instructions:
•
•
•
•
•
This device complies with Part 15 of the FCC rules.
Operation is subject to the condition that this device does
not cause harmful interference. In addition, changes or
modification to this equipment not expressly approved
by the E.F. Johnson Company could void the user’s
authority to operate this equipment (FCC Rules, 47CFR
Part 15.19).
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 bodyworn 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 environment RF exposure limits.
Use only EFJohnson approved supplied or replacement antennas, batteries, and accessories. Use of nonEFJohnson approved antennas, batteries, and accessories may exceed the FCC RF exposure guidelines.
For a list of EFJohnson approved accessories, see the
service manual or marketing accessory lists or contact
the E.F. Johnson Company
USAGE COMPATIBILITY
DO NOT operate it in areas that are sensitive to RF

may include gas stations, fuel and chemical storage and
transfer stations, below deck on boats, and areas where
the air contains flammable chemicals or particles such as
grain dust or metal powders.
BATTERY DISPOSAL
Dispose of the nickel metal-hydride (NiMH) battery
used by this radio in accordance with local regulations.
DO NOT dispose of it in fire because it can explode.
Also, do not short the terminals because it may become
very hot.

SECTION 3 GENERAL OPERATION
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.
3.1 TURNING POWER ON AND SETTING
VOLUME
3.1.1 POWER UP
Power is turned on and off by the top panel OnOff/Volume switch. When power is initially turned on,
the following events occur:
•
•
•
•
•
•
•
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 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.
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:
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 accidentally 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).
•
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/SmartZone or P25 Trunked channel is selected, the
receiver cannot be manually unsquelched.
3.2 POWER-UP PASSWORD
3.2.1 GENERAL
3.1.3 SETTING VOLUME LEVEL
The power-up password feature prevents unauthorized 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.
The volume level is adjusted by the top panel
volume control knob or by option buttons programmed
When it is enabled, “ENTER PSWD” is briefly
displayed when power is turned on. The eight-digit

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.
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.
Channel Select
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.
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).
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 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 current User password can be changed if the
“Set User Password” option switch or menu parameter 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.
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.
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.
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).
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 applicable).
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 channels 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.

•
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.
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.
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, “Unprogrammd” 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. 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.
3.4 LOW BATTERY INDICATION
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.
3.4.1 GENERAL
NOTE: If the radio contains encryption keys and is not
programmed for infinite key retention, be sure to reattach a battery within approximately 30 seconds to
prevent the loss of these keys (see following).
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.
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.
15
GENERAL OPERATION
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.
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.
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).
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 approximately 30 seconds without a battery attached. Therefore, be sure to reattach a battery within that time. Refer
to Section 10.2 for more information on encryption
keys.
3.6 KEYPAD LOCK
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.
The Keypad Lock feature temporarily disables
the front panel keys to prevent keys from being accidentally 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).
3.4.2 BATTERY CHARGING
NOTE: When a battery is charged while attached to
the radio, make sure radio power is off (see following).
Permanent Keypad Lockout can also be
programmed. The keypad is then permanently disabled
and cannot be enabled by the user. Additional information on this feature is as follows:
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 approximately 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
16
•
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 Permanent 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
tional channel selects a transmit and receive frequency
and other channel parameters such as squelch control
coding.
channel selector is always disabled regardless of the
Permanent Lockout or Keypad Lock status. Channels 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.
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 channels 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 communication to occur. In addition, to receive standard group
calls, the receiving radio must be programmed to detect
the transmitted talk group ID code.
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.
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.
3.8 TRANSMIT DISABLE
Transmitting can be disabled on each conventional, 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.
3.9.3 SMARTNET/SMARTZONE MODE
3.9 RADIO OPERATING MODES
This is a trunked operating mode in which automatic 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.
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.
SMARTNET and SmartZone operation and
programming is very similar. Basically, SMARTNET
operation is limited to a single repeater site and SmartZone 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).
3.9.2 CONVENTIONAL MODE
This is a non-trunked operating mode which
accesses independent radio channels. There is no automatic access to several channels. Selecting a conven-

GENERAL OPERATION
Subsystem ID (RFSS). The SmartZone mode does
not use the WACN and RFSS IDs.
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
register on the radio system. If a control channel could
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.
•
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.
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 information 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.
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.
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:
•
•
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.
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.
•
Channels
Digital signaling is always used with P25 calls.
Either analog or digital signaling may be used for
SmartZone calls.
•
P25 Unit IDs can be 1-16,777,215 (000001-FFFFFF
hex) and SmartZone Unit IDs can be 1-65,535
(0001-FFFF hex).
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 channels can belong to a single system or multiple systems.
The P25 mode uses a system ID, Wide Area
Communications Network (WACN) ID, and RF
18
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 conventional 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.

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.
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 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.
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.
4.2 MENU MODE
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.
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.
3. To display the available modes for a highlighted
parameter, press the F2 switch. The currently
selected mode is indicated by an asterisk.
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.
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.
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.

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).
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 continuous 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 channels, a penalty time may also be programmed that
prevents transmissions for a certain time after the
transmitter is disabled (see Section 5.6).
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 Surveillance mode is programmed (see following), tones are
totally disabled.
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 parameter 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.
The Alert Tone volume can be adjusted relative to
the volume control setting. This is done by programming 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.
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.
4.7 SURVEILLANCE MODE
4.5 POWER OUTPUT SELECT
The Surveillance mode totally disables the backlight, 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.
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 transmitter 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
icon is no longer indicated.
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.
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 automatically 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.
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.
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 scanning is not available.
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 operates 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
•
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.
23
RADIO-WIDE FEATURES
2. The channel is then deleted and scanning of the
remaining channels in the scan list resumes.
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.
3. Deleted channels are added back into the scan list if
any of the following occur:

Scan option switch or menu parameter.
Radio power is turned off and then on again.
The selected channel is changed.
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.
4.9 SCAN LISTS
4.9.1 PRIORITY SCAN LISTS
General
SMARTNET/SmartZone/P25 Trunked
Operation - If scanning is halted to receive a
message, programming determines if transmissions occur on the selected or active channel.
Transmissions at other times occur on the selected
channel.
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.
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.
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).
4.8.6 NUISANCE CHANNEL ADD/DELETE
With priority scanning, channels can be temporarily deleted from the scan list, for example, if
messages become annoying. This feature is not available 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:
1. Enable priority scanning using the Scan switch or
menu parameter. Also select the scan list if applicable as described in the following “Selecting a
Priority Scan List” description.
NOTE: The selected channel and also priority channels cannot be deleted from the scan list.
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.
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).

Selecting a Priority Scan List
NOTE: Only priority scan lists are selectable.
Editing a Priority Scan List
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 conventional 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 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 scanning are off (
icon not displayed). Select a
conventional or SMARTNET/SmartZone/P25
Trunked channel corresponding to the scan list
being programmed.
If the Scan (List) Select option switch or menu parameter 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.
2. Select the scan edit mode using the Scan Edit option
switch or menu parameter. This mode is indicated
by
in the display.
SMARTNET/SmartZone and Project 25 Trunked
Channels - Each channel (talk group) can be

selected or scanning is disabled (No List). In addition,
channels can be programmed so that scanning is automatically enabled (Auto Scan) when they are selected.
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.
If the Scan (List) Select option switch or menu parameter 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.
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.
To change the currently selected scan list (all
channel types), proceed as follows:
NOTE: Priority channels can be deleted.
1. With scanning disabled (

SECTION 5 CONVENTIONAL MODE FEATURES
the Monitor Mode (see following) or by the Normal/
Selective option switch or menu parameter (see Section
5.5.5).
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 information on features common to all operating modes.
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:
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 conversation. With SMARTNET/SmartZone and P25 Trunked
operation, monitoring is performed automatically.
Monitor conventional channels automatically or
manually 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.
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.
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.
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:
3. To disable the monitor mode and return to normal
operation, press the Monitor option switch again of
select the Monitor menu “Off” parameter.
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).
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
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

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.
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.
Off - Busy channel lockout is disabled and the transmitter 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.
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.
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
A reverse burst is transmitted when the push-totalk 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 eliminates 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.
5.5.1 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.
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 turnoff code is transmitted which eliminates the squelch
tail similar to the reverse burst.
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 attenuated by a filter. Call Guard squelch must be used in
both the transmitting and receiving radio to be functional.
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.
Proceed as follows to select a code using the
Squelch Select List option button or menu parameter:
5.5.5 SELECTIVE SQUELCH CODE SELECT
(CTCSS/DCS/NAC)
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).
NOTE: Call Guard codes can be permanently reprogrammed by keypad programming described in
Section 5.18.
This feature allows the normal transmit and
receive Call Guard (CTCSS/DCS/NAC) programming to be temporarily overridden with a code
selected from a preprogrammed list. It is available if
the Squelch Select List option switch or menu parameter and a CTCSS/NAC code list have been
programmed.
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 selection and then again to return to normal operation.
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.
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 talkaround channel is selected.
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 (selective squelch disabled) can be programmed if desired.
In addition, each position can be programmed with an
NAC code for use with P25 operation.
5.6 PENALTY TIMER
A penalty timer may be programmed on conventional 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.
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 talkaround channel is selected, the normal codes are reselected. 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.
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 transmission as with the time-out timer. The following is
more information on this timer.
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)

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.
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 continuous 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).
5.10.2 EMERGENCY ALARMS
5.8 REPEATER TALK-AROUND
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.
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.
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 information on MDC1200 Emergency Alert.
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 scanning, 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.
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.
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.
5.10.1 INTRODUCTION
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 indication 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.
Emergency Alarms and Calls are separate functions that can be individually enabled or disabled on
each analog and P25 conventional system. The Emer-

and neither occur if Silent operation is programmed.
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.
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
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.
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 Emergency 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.
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.
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.
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.
Emergency Hot Mic
If Emergency Hot Mic has been enabled for
emergency calls, automatic transmitting occurs with
microphone audio unmuted without having to manually press the PTT switch. The automatic transmit
period is programmed for 10-120 seconds in 10second 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 function, the channel must be changed or power cycled.
5.11 CONVENTIONAL MODE SCANNING
5.11.1 GENERAL

CONVENTIONAL MODE FEATURES
frequency as the priority channel and is programmed
with CTCSS/DCS squelch control.
5.11.2 TRANSMITTING IN SCAN MODE
Each conventional scan list can be programmed
for one of the following modes. These modes determine 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.
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.
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.
The priority channel sampling frequency is determined 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/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.
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.
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.
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.
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.
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.
NOTE: The priority channel is not scanned if the
active channel is an analog channel on the same

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.
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.
4. Press (and hold) the PTT switch to talk and release
it to listen.
Receiving a Standard Conventional Call
Proceed as follows to change the priority channel
using the Priority option switch/menu parameter:
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).
1. Make sure scanning is disabled (
icon not
displayed) and the desired scan list is selected (see
Section 4.9).
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.
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.
•
5.13 DTMF/ANI SIGNALING
DTMF (Dual Tone Multi-Frequency) tones can
be generated for ANI (Automatic Number Identification) 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.
If no indication displayed, the scan list may not be
user editable or the channel may not be in the scan
list.
Post-Tx ANI - A preprogrammed ANI sequence is
automatically sent each time the PTT switch is
released.
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).
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
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.
This feature allows the user to transmit a single
tone by pressing the Single Tone Encoder option
switch or selecting that menu parameter. Each conventional system can be programmed for a tone of 5002500 Hz in 1 Hz steps with a duration of 0.5-2.5
seconds in 0.1 second steps.
2. Monitor the channel automatically or manually as
described in Section 5.2.

CONVENTIONAL MODE FEATURES
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.
5.15 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.
5.16.3 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.
5.16 CLONE MODE
2. On the master radio, select the Clone menu parameter 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 selectable, proceed to step 4.
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).
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. Information 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.
Only zones with conventional analog and P25
channels can be transferred using this function. Any
SMARTNET/SmartZone and P25 trunked information 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 indicated in the slave radio by an asterisk in the first character 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 conventional channels only.
Complete - This mode transfers all conventional
programming information. This includes information on the Global, Radio Wide, and By System
screens. Simply highlight “Complete” and press the

P25 PTT ID- The unit ID of the radio placing the
call is displayed.
5.17 PROJECT 25 MODE FEATURES
P25 Talk Group - The alias of the talk group on
which the call is being received is displayed.
NOTE: The following features are unique to
conventional P25 channels.
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.
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.
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:
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
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.
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 monitoring 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.
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.
5.17.4 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.
5.17.5 P25 UNIT CALLS
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

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.
Telephone calls can be placed and received on
P25 conventional channels. This feature allows telephone 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:
•
•
•
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.
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.
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.
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)#.
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.

option switch.
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.
6.10.3 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 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.
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, Emergency Alarms are disabled. The alarm is sent on the
control channel using Motorola proprietary signaling.
Proceed as follows to send an emergency alarm:
Emergency Hot Mic
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.
If Emergency Hot Mic has been enabled for
emergency calls, automatic transmitting occurs with
microphone audio unmuted without having to manually press the PTT switch. The automatic transmit
period is programmed for 10-120 seconds in 10second 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.
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 indication continues to flash until the alarm mode is ended
(see step 4). If silent 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.
Placing an Emergency Call
1. If required, select a channel of a system on which
Emergency Calls are enabled and press the Emergency option switch or select that menu parameter.
The Emergency Alarm is then sent as described in
Section 5.10.2 if applicable.
3. When the emergency alarm is acknowledged, “ACK
RCVD” is briefly displayed and the emergency
acknowledge tone (two beeps) sounds. Silent operation may also be programmed in which case no tone
sounds and there is no indication that an acknowledgment occurred.
1. The emergency mode is indicated when “ACK
RCVD” is briefly displayed and then
“EMERGNCY” and the emergency talk group are
alternately displayed.
4. The radio continues to transmit this message until an
acknowledgment is received or the programmed
number of attempts have been made. The emergency alarm mode is exited when radio power is
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.
6.12 SMARTNET/SMARTZONE/P25 TRUNKED
SCANNING FEATURES
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 Emergency” is programmed, receive audio, the front
panel LED, and receive icons are disabled in the
receive mode.
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 determines 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.
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/SmartZone 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 continuous tones sounds until the PTT switch is released.
When the radio system returns to normal operation,
this is automatically detected and normal operation
resumes.
6.12.2 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.
49
SMARTNET/SMARTZONE/P25 TRUNKED FEATURES
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:
6.13 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.
6.14.2 BUSY OVERRIDE
The busy override feature is enabled at the system
level by the system manager and is not a programmable 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:
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.
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.
Dynamic regrouping operates as follows:
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.
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.
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.
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 transmissions are allowed.
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.
6.14 SMARTZONE AND P25 TRUNKED
UNIQUE FEATURES
6.14.1 INTRODUCTION
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

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.
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.
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 available, the Out-of-Range condition tells the user to
attempt communication on another system or by some
other means.
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.
6.14.7 P25 WIDE AREA SCAN
Introduction
6.14.5 LOCKING/UNLOCKING A SITE
This feature is intended to enhance roaming
performance, especially when system level steering
via radio or talk group permissions is used.
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.
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) adjacent 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.
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).
Talkgroup Steering Via System Access Permissions
With the Zone Fail Site Lock feature enabled, the
radio continues to roam normally when the system
In order to use system channel resources more
efficiently, some system operators are using system
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.

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES
2. When another talk group is selected, the active valid
site for TG1 is stored in EEPROM memory.
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.
3. The next time TG1 is selected, the following procedure is performed before performing the normal
hunt methods previously described.
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.
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.
P25 Wide Area Scan
c. The best receive/transmit information is used and
the radio checks to see if this control channel is
available.
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:
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.
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.

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.
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 the Keypad Programming option switch is
available, you can reprogram some conventional
channel parameters. Refer to Section 5.18 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.
7.4 SPEAKING INTO MICROPHONE
If “UNPROGRAMD” is displayed, the cause
could be any of the following:
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 (pushto-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 transmitted by your radio. Communication may be
improved by moving to higher ground or away from
shielding objects such as tall buildings or hills.
•
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.
7.6 LICENSING
A government license is usually required to
operate this radio on the air.

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.
[1] 4100 radios require that this option be enabled to roam
across zone controller boundaries.
Currently, the only operating mode that is standard with all models is the conventional analog mode.
Other variables such as frequency range are hardware
dependent instead of software dependent.
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:
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 software. This is initiated by clicking the “Update
Options” button on the Radio Options screen shown in
Figure 8-1.

SECTION 9 PASSWORD DESCRIPTION
following). If even the Master password is lost or was
not used, all passwords can be erased using the
PCTune software as follows:
9.1 NEW PASSWORD ENHANCEMENTS
9.1.1 INTRODUCTION
1. With PCTune 1.1.1.0 or later, simply select Radio >
Reset Passwords. Only password information is
erased.
A new enhanced password feature is now available 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
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 PROGRAMMING PASSWORDS
9.2.1 GENERAL
With new versions of PCConfigure, the “Password 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.
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.
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.
9.2.4 PASSWORD ENTRY PROCEDURE
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.
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.
9.2.2 LOST PASSWORDS
If a password is lost, it can be changed using
PCConfigure by entering the Master password (see

PASSWORD DESCRIPTION
the other passwords. It does not override the following
Zone Password.
9.3 PASSWORD DESCRIPTION
9.3.1 USER (POWER-ON) PASSWORDS
9.4 ZONE PASSWORD
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 Password at power up enables normal radio operation.
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 unauthorized reprogramming of zones by keypad programming. 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.
9.3.2 DOWNLOAD/UPLOAD PASSWORDS
Separate Download (write) and Upload (read)
passwords can be programmed to prevent unauthorized 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.
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.
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

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 encryption device and encryption codes.
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) channels. 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 software. AES encryption, like DES encryption, is an
optional radio feature that must be purchased and then
enabled at the factory.
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 selection, 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™
10.1.3 ENCRYPTION AVAILABLE WITH
VARIOUS CHANNEL TYPES
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:
•
Analog Channels
On analog conventional and SMARTNET/SmartZone 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).
DVP (Digital Voice Privacy) is an earlier encryption
method that is self synchronizing using cipher feedback. It was originally designed to be used by
anyone needing protection from unauthorized
eavesdropping.
Digital Channels
•
•
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.
On digital Project 25 and SMARTNET/Smart
Zone channels, the DES-OFB or AES protocol is used.
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.

transmitted in the clear mode (this is possible only if
the channel is strapped to “switchable”) or the key
must be loaded.
10.2 ENCRYPTION KEYS
10.2.2 KEY AND ALGORITHM IDS
10.2.1 INTRODUCTION
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.
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.
10.2.3 PID/SLN KEY MANAGEMENT MODES
NOTE: The term “SLN” from the Project 25 specification is equivalent to “CKR” (Common Key Reference)
also used to define this parameter.
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.
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).
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.
PID or SLN key management modes can be
programmed on the Global programming screen. More
information on these modes follows.
If an attempt is made to transmit a secure
message without loading the corresponding key,
“KEYFAIL” is displayed. The message must then be
PID Mode - The PID mode can be used only when
keys are loaded using the Motorola KVL 3000
62
SECURE COMMUNICATION (ENCRYPTION)
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:
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 Location Number), typically from 0-4095. A Keys Table
must then be programmed to link channel PIDs to a
specific SLN.
1. Press the Key Select switch or select that menu
parameter and HWKEY x is displayed. The “x”
indicates the current key PID selection.
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.
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.
10.2.4 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 Retention parameter determines if keys are permanently
stored in memory or erased soon after power is
removed.
10.2.7 ENCRYPTION ICON OPERATION
Basically, the encryption icon
is on continuously whenever a secure call is received or transmitted. Other operation is as follows:
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.
•
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.
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.
10.3 CLEAR/SECURE STRAPPING
10.2.5 ENCRYPTION KEY SELECT
10.3.1 TRANSMIT MODE OPTIONS
NOTE: This feature is available on conventional
channels only.
The following transmit options are available
when encryption is selected:
63
SECURE COMMUNICATION (ENCRYPTION)
No Autodetect - Only signals coded like the transmit
signals are received.
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 Autodetect - Both clear and secure signals are
automatically detected. This mode is automatically
selected if the transmit mode is switch selectable.
Secure - All calls are made in the selected secure
mode.
Proper Key Autodetect
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.
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.
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 transmission is attempted, “Secure Only” is displayed and the
transmitter is disabled.
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.
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.
10.3.3 TALK GROUP ENCRYPTION OVERRIDE
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).
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 conventional digital channels, encryption can be programmed
differently for each channel. Conventional analog
channel encryption is always programmed on a per
channel basis.
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.
10.4 OTAR (OVER-THE-AIR REKEYING)
10.3.2 RECEIVE MODE OPTIONS
10.4.1 INTRODUCTION
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.
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

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.
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.
Currently, OTAR is available only on P25
conventional channels, and to program DES-OFB and
AES keys (future programming on P25 trunked channels is planned). It is not used on SMARTNET/SmartZone channels or to load DES/DES-XL keys.
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.
10.4.2 ENCRYPTION KEY TYPES
There are two types of keys used with OTAR:
16-Bit Keyset ID
Algorithm ID
Update Item (Opt)
TEK (Traffic Encryption Key) - The key used to
encrypt voice and data traffic. All radios using encryption must have at least one of these keys. This is also
another name for the keys used without OTAR.
(upper 4 bits are
Crypto Group)
Time/Date (Opt)
Keyset Name (Opt)
Key 1
Key 2
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).
Key 4096
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.
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
10.4.5 KEY MANAGEMENT FACILITY
The Key Management Facility (KMF) provides
key management and OTAR functions to applicable

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.
radios within the radio system. One of the main tasks
of the KMF is to maintain a data base of information
Crypto Group ID
(4-Bit = 0-15/0-F)
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.

Keyset ID
8-Bit = 0-255/0-FF
Figure 10-3 Encryption Parameter IDs
When determining this number, consider the likelihood 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 considered when selecting this number.
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
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).
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:
•

•
•

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).
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
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 information.
10.4.6 MESSAGE NUMBER PERIOD (MNP)
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
One of the parameters that is programmed in a
radio utilizing OTAR is Message Number Period
(MNP). This parameter is programmed as described in
66
SECURE COMMUNICATION (ENCRYPTION)
Key ID - This is a 16-bit (four hex digit) number identifier 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.
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.
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.
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 acknowledged.
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).
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.
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 - A variable used by a cryptographic algorithm to
encrypt voice or data. Also called “Cryptographic
Variable”.
Key Loader - Any type of device used to load encryption 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.
Key Encryption Key (KEK) - A key used to encrypt
keys contained in Key Management Messages
(KMMs) during OTAR. These messages may themselves 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.
Logical Link ID (LLID) - An ID transmitted with a
data message to identify the destination of the
message.
67
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).
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.
Over-The-Air-Rekeying (OTAR) - The process of
sending new encryption keys over the air using an RF
interface.
10.5 RADIO SETUP FOR ENCRYPTION
Red - Refers to information that is not encrypted. The
opposite is “Black”.
The following radio setup is required for encryption regardless of whether OTAR is used:
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.
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 software, select the Transfer > Read Options From Radio
menu parameter.
10.5.1 GENERAL ENCRYPTION SETUP
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 individual 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 originates. The KMMs (Key Management Messages)
generated by the KMF (Key Management Facility) are
addressed to a specific RSI.
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).
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).
Program Channel/Group PIDs and Encryption
Type - With conventional analog calls, this information is programmed on the channel screen.
With other types, it is programmed in the talk
group list selected on the system screen. In addition, 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 channels because the AES/DES mode is determined
by the key type loaded, not by PCConfigure
programming.
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.
68
SECURE COMMUNICATION (ENCRYPTION)
Programming By Keyloader
Currently, EFJohnson 41xx portables and 43xx
mobiles that meet the following requirements support
OTAR:
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 temporary TEK is transferred to the radio to perform the key
transfer.
Programming - An RSI and UKEK and other information must be programmed as described in the next
section.
10.5.2 ADDITIONAL SETUP FOR OTAR
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.
Additional PCConfigure Programming For OTAR
The following parameters must be programmed
for OTAR operation in addition to those in Section
10.5.1 .
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 disconnect. However, it may need to be loaded if the radio
is manually deleted from the KMF and then recreated since the message number must be reset to 0
(the Load Target RSI command resets the message
number to 0).
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. KMF RSI - This RSI is normally 9,999,999 and
should not need to be loaded since it defaults to this
number.
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.
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.
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:
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.
LCRD 03 06 00 1234 7F xx xx xx 0A 0A 00 07 00 yy
Keysets
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.

•
•
TEKs and only one is active at a time. Keyset ID 255
is for KEKs and is considered active all the time
same as described in
Section 10.5.
Each keyset can have up to 128 keys. However, 16
or less are normally used.
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.
AES encryption is supported (with Flash code 1.8.0
or later) but not currently available with OTAR
(future availability is planned).
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.
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).
Clear/Secure Select - This enables and disables
encryption regardless of whether OTAR is used. Refer
to Section 10.3 for more information.
OTAR Messages That Are Supported
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 channels 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. Additional 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).
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
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.
70
SECURE COMMUNICATION (ENCRYPTION)
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.
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.
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 communication without initiating the rekeying that occurs
with the preceding “Rekey” function.
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.)
Erase Keys - Erases all keys in the radio the same as
the Erase Keys option switch described in the
preceding section.
Rekey - Performs the same function as the OTAR
Rekey Request option switch described in the
preceding section.
