SAFETY INFORMATION
SAFETY INFORMATION
The FCC has adopted a safety standard for human expo-
sure to RF energy. Proper operation of this radio under
normal conditions results in user exposure to RF energy
below the Occupational Safety and Health Act and
Federal Communication Commission limits.
WARNING
DO NOT allow the antenna to touch or come in very
close proximity with the eyes, face, or any exposed body
parts while the radio is transmitting.
To comply with FCC RF exposure limits, DO NOT
operate the transmitter of a mobile radio when a person
outside the vehicle is within one 1 meter of the antenna
with standard power models or 1.5 meters with high
power (100 watt) models.
To comply with FCC RF exposure limits, DO NOT
operate the transmitter of a stationary radio (base station
or marine radio) when a person is within one 1 meter of
the antenna with standard power models or 1.5 meters
with high power (100 watt) models.
DO NOT operate the radio in explosive or flammable
atmospheres. The transmitted radio energy could trigger
blasting caps or cause an explosion.
DO NOT operate the radio without the proper antenna
installed.
DO NOT allow children to operate or play with this
radio.
NOTE: The above warning list is not intended to
include all hazards that may be encountered when
using this radio.
This device complies with Part 15 of the FCC rules. Oper-
ation is subject to the condition that this device does not
cause harmful interference. In addition, changes or modi-
fications to this equipment not expressly approved by
EFJohnson could void the user’s authority to operate this
equipment (FCC rules, 47CFR Part 15.19).
FCC EXPOSURE LIMITS
This mobile radio transceiver was tested by the
manufacturer with an appropriate antenna in order to
verify compliance with Maximum Permissible Exposure
(MPE) limits set under Section 2.1091 of the FCC Rules
and Regulations. The guidelines used in the evaluation
are derived from Table 1 (B) titled “Limits For General
Population/Uncontrolled Exposure” which is from FCC
report OET bulletin #65.
Table 2 lists the antenna whips and bases recom-
mended for use in each frequency range. Each model of
this radio was tested with the appropriate antenna listed.
The antenna was mounted in the center of the roof of a
domestically manufactured four-door passenger sedan.
The radio manufacturer has determined that the user and
service personnel should remain one (1) meter in
distance away from the antenna when transmitting. By
maintaining this distance, these individuals are not
exposed to radio frequency energy or magnetic fields in
excess of the guidelines set forth in Table 1.
NOTE: Other antennas or installation configurations
that have not been tested may not comply with FCC RF
exposure limits and therefore are not recommended.

GENERAL OPERATION
SECTION 3 GENERAL OPERATION
3.1 TURNING POWER ON AND SETTING
VOLUME
3.1.1 POWER ON/OFF
When power is turned on and off by pressing the
On-Off/Volume knob. When power is turned on, the
radio goes through a self test. When that is success-
fully completed, the unit ID is briefly displayed
(except when a conventional analog channel is
selected), a tone sounds (if tones are enabled), and the
radio is ready for normal operation. If “ENTER
PSWD” is briefly displayed, refer to the next section.
The radio can be programmed* so that one of the
following combinations are selected at power up:
•Last Zone/Last Channel
•Last Zone/Home Channel
•Home Zone/Last Channel
•Home Zone/Home Channel
The Home Zone and Channel are prepro-
grammed. 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 the
home channel is displayed when powering up on the
home zone.
NOTE: In dual control configurations (front mount
radio with remote control unit), one control point must
be off for the other to control power. If not, the other
does not turn power off.
3.1.2 SETTING VOLUME LEVEL
The relative volume setting can be determined
using a reference tone as follows:
•If the key press tones are enabled (see Section 3.11
on page 13), a short tone sounds when an option
switch is pressed or the Select switch is pressed or
rotated.
•If a conventional channel is selected, take the micro-
phoneoff-hookandifsomeoneistalking,voicemay
be heard. If the MON (Monitor) option switch is
programmed (see Section 4.3 on page 19), pressing
it unsquelches the transceiver and either voice or
background noise is heard. If a SMARTNET/Smart-
Zone or P25 trunked channel is selected, the trans-
ceiver cannot be manually unsquelched.
3.2 POWER-UP PASSWORD
The power-up password feature prevents unau-
thorized use of the radio by requiring that an 8-digit
password be entered to make it operational. This
feature is enabled or disabled by the PCConfigure
radio programmer.
When this feature is enabled, “ENTER PSWD” is
briefly displayed when power is turned on. The 8-digit
password must then entered by rotating and pressing
the Select switch. In addition, since the logic resets
whenever data is read or written using the PCCon-
figure programmer, this password must be entered
after performing those functions.
This password can be changed only by the
PCConfigure programmer. It cannot be changed by the
user. If it is lost, all programming must be erased to
make the transceiver operational again. This is done
using the “EEPROM Erase” function of the PCTune
program. Refer to the Alignment Procedure section in
the 5300 Service Manual for more information.
3.3 BACKLIGHT CONTROL AND DISPLAY
VIEWING ANGLE ADJUST
If the BKLHT option switch is programmed, it
can be used to select high, medium, or off backlight
modes. Otherwise, the keypad and display backlight is
fixed in one of these modes by programming. The
backlight is totally disabled when the Surveillance
mode is programmed (see Section 3.15).
If the display is difficult to read from the angle
you normally view it, the viewing angle can be
adjusted as follows: Press and hold the last option

switch above the display and then press the first option
switch above the display. Then release both switches
and turn the Select switch until the best contrast is
obtained. This function times out in 3-5 seconds.
NOTE: If the display appears blank or all icons are
continuously displayed, the viewing angle is probably
improperly adjusted.
3.4 ZONE/CHANNEL DISPLAY
The selected zone and channel numbers are
displayed by the zone and channel displays shown in
the following illustration. In addition, the programmed
zone or channel identification (alias) is displayed in
the alphanumeric display area. The zone alias is
displayed when the zone select mode is enabled, and
the channel alias is displayed when the channel select
mode is enabled (see next section). With conventional
channels, the channel frequency may be displayed
instead of the alias (see Section 4.9).
A zone can include any mix of up to 16 channels,
and up to 16 zones can be programmed. Therefore, up
to 256 channels can be selected. Zones may be used
for operation in different geographical areas or radio
systems.
3.5 ZONE/CHANNEL SELECT
The front panel Select switch is used to change
the zone and channel. Pressing this switch toggles
between the zone and channel select modes, and
rotating it changes the zone or channel.
The current mode is indicated by the bar over the
zone or channel display. For example, when the bar is
over the zone display (see following illustration), the
zone select mode is enabled.
Rotating the Select switch clockwise increases
the zone or channel and rotating it counterclockwise
decreases the zone or channel number. After the
highest zone or channel is displayed, wrap-around to
the lowest zone or channel occurs and vice versa. If an
unprogrammed channel is selected,
“UNPROGRAMD” is displayed and a tone sounds.
The transceiver may also be programmed so that only
programmed channels are selected.
The transceiver can be programmed so that the
bar defaults to either the zone or channel display when
power is turned on and after a change is made. The
delay that occurs before it returns is programmed for
1-15 seconds. It can also be programmed to remain in
the last selected mode.
3.6 SETTING SQUELCH CONTROL
This transceiver does not have a squelch control.
The squelch level is preset and usually does not
require readjustment. However, if the squelch level
needs to be changed on a conventional analog channel,
it can be changed using keypad programming if avail-
able (see Section 4.15 on page 28).
3.7 OPTION SWITCHES
The six option switches on the front panel (one is
located to the left of the display) can be programmed
by the PCConfigure programmer to control a different
set of functions for each of the three operating modes.
Therefore, up to 18 different functions can be
controlled by these switches (six each for conven-
tional, SMARTNET/SmartZone, and P25 Trunking).
The available functions in each mode and the section
in which each is described are shown in Table 3-1
which follows.
3.8 TIME-OUT TIMER
The time-out timer disables the transmitter if it is
keyed for longer than the programmed time. It can be
programmed on each channel for times of 15 seconds
to 3 minutes, 45 seconds or it can be disabled. If the
transmitter is keyed continuously for longer than the
programmed time, the transmitter is disabled, a contin-
uous tone sounds, and “TX TIMEOUT” is displayed.
Five seconds before time-out occurs, a warning beep
sounds to indicate that time-out is approaching. The
timer and tone are reset by releasing the PTT switch. A
different time can be programmed for each system,
and the timer can be enabled or disabled on each
channel.

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.
3.9 HOME ZONE/CHANNEL SELECT
If the HOME zone option switch is programmed,
pressing it selects the preprogrammed home zone and
channel. This provides a quick way of returning to a

13
frequently used zone and channel. The transceiver is
also programmed so that either the home or last
selected zone/channel is automatically selected when
power is turned on (see Section 3.1).
3.10 POWER OUTPUT SELECT
Each conventional channel and SMARTNET/
SmartZone and P25 Trunked system can be
programmed for High, Low, or Switchable transmit
power. If Switchable power is programmed on the
channel, the Tx PWR option switch can then be used
to select high or low transmitter power. All models
support switchable power.
Pressing the TX PWR switch toggles the power
setting. The new level is flashed in the display when
this switch is pressed as “HI POWER” or “LOW
POWER”. If selectable power is not permitted on the
current channel, the fixed power level is flashed as
“FIXED HIGH” or “FIXED LOW” and no power
change occurs. The selected power level for a channel
is permanent until it is manually changed again.The
power levels are set at the factory or when the radio is
tuned using the PCTune™ software. The factory
default low power setting is one-half the high power
setting.
3.11 ALERT TONE SELECT
The various alert tones that sound are described
in Section 6.1 on page 39. These tones can be enabled
and disabled if the TONE option switch is
programmed. To turn all tones off, press this switch
and “TONE OFF” is displayed. Then to turn all tones
on again, press it and “TONE ON” is displayed. If this
switch is not programmed, tones are fixed in the on or
off condition by programming. Alert tones are totally
disabled when the Surveillance mode is programmed
(see Section 3.15).
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 switch 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.
3.12 POWER TURN-OFF DELAY
The transceiver can be installed so that the
vehicle ignition switch as well as the front panel
power switch of the transceiver control power. This is
done by connecting the accessory cable ignition switch
input to the vehicle ignition switch. Refer to the Instal-
lation section of the 5300 Service Manual for more
information. A power-off delay of up to 254 minutes
or forever can then be programmed.
Both the ignition switch and the power switch
must then be on for transceiver power to turn on. The
delay can be overridden at any time by turning power
off using the front panel power switch or turning the
ignition switch back on.
This turn-off delay can allow calls to be received
or the horn alert to be active for a time after the igni-
tion switch is turned off. At the same time, advantages
of ignition switch control are utilized such as
preventing the battery discharge that may occur if the
transceiver is left on for an extended period (see
Section 6.5).
3.13 HORN ALERT
The horn alert feature** sounds an external alert
such as the vehicle horn when certain calls are
received. It is available if a Horn option switch is
programmed and the proper connection has been made
to the external alert. The horn alert output is pin 4 of
the accessory cable, and an external driver circuit of
some type is usually required. Refer to the Installation
section of the 5300 Service Manual for more informa-
tion on how to install this feature.
Additional information on the horn alert feature
follows:
•It activates when receiving any Unit call in the
conventional mode and any Private/Unit and Call
Alert (paging) call in the SMARTNET/SmartZone
and P25 Trunked modes. It does not sound when
receiving standard Group or telephone calls, and is
not programmable on a per call basis.
•It must be manually enabled and disabled by the
Horn option switch. It is not controlled by the

vehicle ignition switch. When it is enabled, “HORN
ON” is briefly displayed, and when it is disabled,
“HORN OFF” is briefly displayed. It defaults to the
off mode whenever power is turned on.
•If a power turn-off delay is programmed as just
described, it is functional during that delay.
•When activated, it can be programmed to sound for
three 1-second beeps or continuously for 2-90
seconds. It then turns off until another call is
received.
3.14 MICROPHONE OFF-HOOK DETECT
The microphone hanger can be connected to
chassis ground and the radio programmed to detect an
off-hook condition (Hangup Box Monitor selected).
The following operation then occurs when the micro-
phone is taken off-hook:
Conventional Channel Selected - Scanning tempo-
rarily halts (if applicable) and the Monitor Mode
described in Section 4.3 is enabled. However, the
receiver unsquelches only if a carrier is detected.
SMARTNET/SmartZone/P25 Trunked Channel
Selected - Scanning temporarily halts if applicable.
If the off-hook condition is not detected (Hangup
Box Monitor not selected), the microphone hook state
has no affect on radio operation.
3.15 SURVEILLANCE MODE
If the Surveillance mode* is programmed, the
backlight, all alert tones, and front panel LED indi-
cator are totally disabled in all operating modes.
This feature can be turned on and off** by the
user if the Surveillance Mode option switch is
programmed. The user selected mode permanently
overrides the programmed mode if applicable.
3.16 PUBLIC ADDRESS
An external public address system can be
connected to pin 7 of the radio accessory pigtail cable.
A PA option switch is required to control this feature.
In the public address mode, microphone audio is
always routed to the PA system, and the radio can be
programmed so that receive audio is also routed.
When the PA is enabled/disabled, “Ext PA On/Off” is
displayed momentarily. The radio can also be
programmed to display “Ext PA On” continuously.
3.17 SCANNING
3.17.1 INTRODUCTION
Scanning monitors the channels in the scan list
for messages the transceiver 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).
If the microphone off-hook condition is detected
(Hangup Box Monitor selected by programming),
scanning stops and selective squelch (such as Call
Guard CTCSS or NAC/group ID detect) is disabled on
conventional channels. If the off-hook condition is not
detected, taking the microphone off-hook has no affect
on transceiver operation.
There are two scan modes available: Standard and
Radio Wide. The standard type is unique to the type of
channel selected, and the Radio Wide type is the same
for all channel types. Only one type of scanning can be
enabled at a time. Therefore, if standard scanning is
enabled when the Radio Wide Scan switch is pressed,
standard scanning is automatically disabled and vice
versa. Refer to the following for more information.
3.17.2 STANDARD SCANNING
Standard scanning 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. For more information on scanning functions
unique to these operating modes, refer to Sections 4.11
and 5.12. Standard scanning operates as follows.
•To turn standard scanning on, press the SCAN
option switch. Scanning is enabled when a rotating
is indicated in the right status display as follows
and “SCAN ON” is briefly displayed.
* This feature requires 53xx operating (ARM) software
1.16 or later. ** This feature requires 53xx operating (ARM) software 1.22 or later and PCConfigure 1.20 or later.

GENERAL OPERATION
15
•To turn scanning off, press the SCAN option switch
again. On conventional channels, this may also
select another list, so several presses may be
required (see Section 4.11). Scanning is disabled
when “SCAN OFF” is briefly displayed and is no
longer indicated in the status display.
•If the zone or channel is changed while scanning is
selected, scanning continues on the same or a
different scan list (see Section 3.18.1).
NOTE: Each SMARTNET/SmartZone and P25 trunked
channel can be programmed so that scanning is auto-
matically enabled when the channel is selected.
3.17.3 RADIO WIDE SCANNING
NOTE: Use radio wide scanning only if two types of
channels need to be scanned at the same time such as
conventional and SMARTNET/SmartZone. Otherwise,
use the more efficient standard scanning because there
is less chance of missed calls.
Radio wide scanning monitors the channels in the
preprogrammed radio wide scan list. This list may
contain up to 16 channels of any type assigned to any
zone (see scan list description in Section 3.18.1).
Radio wide scanning is turned on and off by the RWS
option switch as follows. If this switch is not
programmed, radio wide scanning is not available.
•To turn radio wide scanning on, press the RWS
option switch and “RSCN ON” is briefly displayed.
In addition, is displayed the same as with stan-
dard scanning.
•To turn radio wide scanning off, press the RWS
option switch again and “RSCN OFF” is briefly
displayed and is no longer displayed.
•If the zone or channel is changed while radio wide
scanning, scanning continues normally.
3.17.4 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.
Separate delay times are programmable for radio
wide and standard scanning. With radio wide and
conventional standard scanning, delays of 0-7.5
seconds are programmable in 0.5-second steps. With
SMARTNET/SmartZone and P25 Trunked standard
scanning, a delay of 2-10 seconds can be programmed
in 0.5-second steps.
3.17.5 TRANSMITTING IN THE SCAN MODE
If the transmitter is keyed while scanning is
enabled, transmissions occur on various channels as
follows.
Conventional Operation - Transmissions can occur
on the priority, selected, or receive channel. Refer
to Section 4.11 for more information.
SMARTNET/SmartZone/P25 Trunked Operation -
If scanning is halted to receive a message,
programming determines if transmissions occur on
the selected or receive channel. Transmissions at
other times occur on the selected channel.
3.17.6 NUISANCE CHANNEL DELETE
With standard scanning, channels can be tempo-
rarily deleted from the scan list, for example, if
messages on a channel become annoying. This feature
is not available with radio wide scanning. Channels
can also be permanently added or deleted by editing
the scan list as described in Section 3.18.5. Proceed as
follows to temporarily delete a channel:
NOTE: The selected channel and also conventional
priority channels cannot be deleted from the scan list.
1. While receiving a message on the channel to be
deleted, press and hold the SCAN option switch
until a tone sounds (approximately 2 seconds).
Scan Enable Indicator

GENERAL OPERATION

2. The channel is then deleted and scanning of the
remaining channels in the scan list resumes.
3. Deleted channels are added back into the scan list if
any of the following events occur:
•Scanning is turned off and then onagain usingthe
SCAN switch.
•Transceiver power is turned off and then on again.
•The scan list is reselected by changing channels
(SMARTNET/SmartZone) or using the SCAN
option switch (conventional).
3.18 SCAN LISTS
NOTE: A scan list is simply the channels that are
scanned when scanning is enabled.
3.18.1 STANDARD MODE SCAN LISTS
NOTE: The selected channel is always scanned.
With all operating modes, as many standard scan
lists as are required can usually be programmed (up to
256). The only limitation is the available memory.
Each list can include up to 256 channels/talk groups.
Scan List Select - Refer to “Selecting a Scan List”
which follows for information on selecting a scan list.
Scan List Edit - Refer to “Editing a Scan List” which
follows for information on editing a scan list.
3.18.2 RADIO WIDE SCAN LIST
With radio wide scanning, there is only one scan
list and it can include up to 16 channels of any type.
For example, it could include six conventional chan-
nels and ten SMARTNET/SmartZone channels. The
channels in this list are not user programmable.
3.18.3 DETERMINING WHICH CHANNELS ARE
IN SCAN LIST
Channels in the radio wide and conventional stan-
dard scan lists are determined as follows. Channels in
the SMARTNET/SmartZone/P25 Trunked standard
scan lists are indicated only when editing a list.
1. Enable Standard scanning to view the standard list
or Radio Wide scanning to view the radio wide scan
list (the procedure is on page 14). Also select the
scan list if applicable as described in the following
“Selecting a Scan List” description.
2. Select the desired zone and then scroll through the
channels by rotating the Select switch. When the
displayed channel is in the scan list (scanned
normally), the symbol is displayed next to the
zone number as shown in the following illustration
.
3.18.4 SELECTING A SCAN LIST
Conventional Operation - The scan list is user select-
able by the SCAN option switch. Refer to Section 4.11
for more information.
SMARTNET/SmartZone/P25 Trunked Operation -
The scan list can be temporarily changed if the Scan
(List) Select option switch is programmed. Refer to
Section 5.12.3 for more information.
3.18.5 EDITING A SCAN LIST
If the SCN ED (Scan Edit) option switch is
programmed, standard scan lists can be user edited as
follows (all operating modes):
1. Make sure that both standard and radio wide scan-
ning are off (the rotating icon is not indicated in
the right status display). Select a conventional,
SMARTNET/SmartZone/P25 Trunked channel
corresponding to the scan list being edited.
2. Select the scan list edit mode by pressing the SCN
ED option switch. This mode is indicated by a
triangle in the upper left corner of the display (see

4. Select the channel you want to add or delete by
rotating the Select switch. After the last channel in
the current zone is displayed, the first valid channel
inthenextzoneisdisplayedandviceversa.Listsare
limited to 256 channels. If an attempt is made to add
more than 256, “LIST FULL” is displayed and a
channel must be deleted before another can be
added.
NOTE: A conventional priority channel cannot be
deleted (see Section 4.11.4).
5. If the selected channel is in the scan list (scanned),
the symbol is displayed next to the zone number
as described on page 16. To change the scan list
status of the displayed channel, press the Select
switch.
With conventional channels only, if the selected
scan list is programmed with fixed priority
channel(s),thenext pressofthe Select switchmakes
the current channel the priority channel indicated by
“P” in the left status display next to the zone
number. If dual priority channels are used, pressing
the Select switch again makes it the second priority
channel indicated by “2” in the left status display.
Then pressing the Select switch again takes the
channel out of the scan list. Refer to Section 4.11.4
for more information on priority channel sampling.
6. To exit this mode and save the changes, press the
SCN ED option switch again.
3.19 TRANSCEIVER OPERATING MODES
3.19.1 GENERAL
Each selectable channel can be programmed for
the conventional (analog or Project 25 digital),
SMARTNET/SmartZone, or Project 25 digital trunked
operating mode. For example, Zone 1/Channel 1 could
be a conventional channel, Zone 1/Channel 2 a
SMARTNET channel, and so on. More information on
these modes follows.
3.19.2 CONVENTIONAL MODE
This is a non-trunked operating mode which
accesses independent radio channels. There is no auto-
matic access to several channels. Selecting a conven-
tional channel selects a transmit and receive frequency
and other channel parameters such as squelch control
coding.
Conventional channels can be either standard
(analog) or Project 25 (digital). With digital operation,
the DSP (Digital Signal Processor) converts the audio
signal to digital data which is sent over the air as
complex tones. Another difference is that analog chan-
nels use Call Guard (CTCSS/DCS) squelch control
and Project 25 channels use a NAC (Network Access
Code) and talk group ID codes.
With Project 25 operation, a NAC is transmitted
and it must match the NAC programmed in the base
equipment and the mobile(s) being called for commu-
nication to occur. In addition, to receive group calls, the
receiving mobile must be programmed to detect the
transmitted talk group ID code.
With conventional operation, a busy channel
condition is detected automatically if the busy channel
lockout (transmit disable on busy) feature is
programmed. Otherwise, it must be detected manually.
An out-of-range condition is not indicated by special
tones or messages as with SMARTNET operation
because there is no initial data exchange with the
repeater that allows this condition to be detected.
Operating features unique to conventional channels
are described in Section 4.
3.19.3 SMARTNET/SMARTZONE MODE
This is a trunked operating mode in which auto-
matic access is provided to several RF channels. ID
codes are used to select what mobiles are being called
and what calls are received. Monitoring is performed
automatically and special messages and tones indicate
busy and out-of-range conditions.
SMARTNET and SmartZone operation and
programming is very similar. Basically, SMARTNET
operation is limited to a single repeater site and Smart-
Zone operation allows automatic roaming between
sites. Enhanced SMARTNET/SmartZone features

include roaming (SmartZone only), telephone*,
private, and emergency calls, Call Alert™, and
messaging. Either analog or digital signaling may be
used.
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.
The control channel transmits and receives
system information to and from all radios registered on
the system. Therefore, once a control channel is found,
it is continuously monitored for incoming call infor-
mation and is used to make call requests. The radio
automatically changes to a traffic channel to place and
receive calls and then returns to the control channel
when the call is complete. Operating features unique
to SMARTNET/SmartZone channels are described in
Section 5.
3.19.4 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
5. Some differences between the P25 Trunking and
SmartZone modes are as follows:
•Digital signaling is always used with P25 calls.
Either analog or digital signaling may be used for
SmartZone calls.
•Calls made to a specific mobile 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.
•Telephone calls are currently not available in this
mode.
•The P25 control channel data rate is 9600 baud and
the digital voice data rate is also 9600 baud. With
SmartZone operation, the control channel data rate
is 3600 baud (both digital and analog calls) and the
narrowband digital voice data rate is 9600 baud.
•The P25 mode uses a system ID, Wide Area
Communications Network (WACN) ID, and RF
Subsystem ID (RFSS). The SmartZone mode does
not use the WACN and RFSS IDs.
•P25UnitIDscanbe 1-16,777,215(000001-FFFFFF
hex) and SmartZone Unit IDs can be 1-65,535
(0001-FFFF hex).
3.19.5 SYSTEMS, CHANNELS, AND ZONES
A zone and channel are selected to place and
receive calls. The following describes the relationship
between systems, channels, and zones.
Systems
A system is a collection of channels or talk
groups belonging to the same repeater site. It defines
all the parameters and protocol information required to
access a site. Up to 16 systems of any type can be
programmed.
The maximum number of channels assignable to
a system is limited to 256. Channels may also be
limited by available memory space as described in the
following information.
Channels
A channel selects a radio (RF) channel or talk
group as follows:
Conventional Analog Mode - A channel selects a
specific radio channel, Call Guard (CTCSS/DCS)
squelch coding, and other parameters unique to that
channel.
Conventional Project 25 Mode - A channel selects a
specific radio channel, NAC squelch coding, talk
group ID, and other parameters unique to that channel.
Mode - A channel selects a specific talk group ID and
other parameters unique to that talk group.
SMARTNET/SmartZone and Trunked Project 25
Modes - A channel selects a specific talk group,
* This feature requires 53xx operating (ARM) software
1.17 or later.

CONVENTIONAL FEATURES
19
announcement group, emergency group, and other
parameters unique to that talk group.
A maximum of up to approximately 256 channels
can be programmed with the preceding modes. These
channels can belong to a single system or multiple
systems. The maximum number is also limited by the
available memory. For example, since more memory is
required to program a SMARTNET system than a
conventional system, the total number of channels
decreases as the number of SMARTNET channels
increases. The programming software displays a bar
graph which shows the amount of available memory
space that is used by the current data.
Zones
A zone is a collection of up to 16 channels of any
type. For example, a zone could include 12 conven-
tional channels and 4 SMARTNET channels. One use
of zones may be to program the channels used for
operation in a different geographical areas. The
maximum number of zones is 16.
SECTION 4 CONVENTIONAL FEATURES
4.1 INTRODUCTION
An overview of the conventional operating mode
is located in Section 3.19.2. The following information
describes the features unique to conventional standard
(analog) and Project 25 (digital) operation. Refer to
the preceding “General Operation” section (Section 3)
for information on features common to all operating
modes.
4.2 MONITORING BEFORE TRANSMITTING
With conventional operation, you may need to
manually monitor the channel before transmitting to
make sure that it is not being used by someone else. If
you were to transmit while someone else was using the
channel, you would probably disrupt their conversa-
tion. With the trunked operating modes, channel moni-
toring is performed automatically. Monitor conven-
tional channels automatically or manually as follows:
Automatic Channel Monitoring
If the selected channel is programmed for Busy
Channel Lockout (also called Transmit Disable On
Busy), monitoring is performed automatically. Refer
to Section 4.4 for more information on this feature.
Manual Channel Monitoring
The automatic monitoring just described may
occasionally disable the transmitter when the channel
is not in use, such as when the repeater has extended
hang time. In this case, you may not want to use it and
the channel must then be monitored manually as
follows:
Busy Indicator - With scanning disabled, note if the
multi-function indicator on the front panel is steady
green. If it is not, the channel is not being used and
you can transmit your call. If it is green, a carrier is
being detected, so the channel may be busy (see next
paragraph).
Monitor Mode - There may be times when the busy
indication is displayed even though no one is using the
channel. Monitoring should then be performed by
disabling Call Guard squelch (or group ID detect on
P25 channels). This is usually done by selecting the
Monitor Mode (see following).
4.3 MONITOR MODE
The monitor mode unsquelches the receiver and
monitors the channel even if a carrier is not detected.
Other features of this mode are as follows:
•Call Guard (CTCSS/DCS) squelch is disabled on
analog channels and NAC and group ID detect are
disabled on P25 (conventional) channels.
•Busy Channel Lockout is overridden (see next
section)
•Scanning temporarily halts
The Monitor Mode operates as follows:

CONVENTIONAL FEATURES
20
1. To monitor the transmit frequency for activity
before transmitting, briefly press the MON option
switch. The display then indicates “MON” (see
Figure 2-3 on page 8) and the receiver unsquelches.
2. To monitor the receive frequency instead, press and
hold the MON option switch until a tone sounds
(approximately 2 seconds). This can be used, for
example, to improve reception if intermittent
squelching is making a weak message difficult to
understand.
NOTE: If microphone off-hook detection is
enabled, the opposite of the above occurs.
3. To disable the monitor mode and return to normal
operation, press the MON option switch again.
If off-hook detection is enabled, taking the micro-
phone off-hook monitors the receive frequency similar
to step 2. However, the receiver unsquelches only if a
carrier is detected (see Section 3.14). Pressing theSEL
SQ option switch disables Call Guard squelch/P25
group ID detect but not scanning and P25 NAC detect
(see Section 4.5).
4.4 BUSY CHANNEL LOCKOUT
The Busy Channel Lockout (also called Transmit
Disable on Busy) feature automatically disables the
transmitter if the channel is busy when the PTT switch
is pressed. When the transmitter is disabled by this
feature, “BUSY” is displayed, a busy tone sounds, and
the transmitter is disabled.
The Busy Channel Lockout feature can be
programmed to operate as follows. Each conventional
channel can be programmed differently.
Off - Busy channel lockout is disabled and the trans-
mitter keys even if the channel is busy.
Noise - If a carrier is detected on the channel, the
transmitter is disabled when the PTT switch is pressed.
Tone (NAC) - If an incorrect Call Guard (CTCSS/
DCS) or P25 NAC code (see Section 1.4) is detected,
the transmitter is disabled when the PTT switch is
pressed. An incorrect code is any code other than the
one programmed for the current channel.
If Busy Channel Override is permitted by
programming, it is possible to transmit even when the
transmitter is disabled by this feature. Simply release
the PTT switch and then quickly press it again.
4.5 CALL GUARD SQUELCH
4.5.1 INTRODUCTION
Tone or digital Call Guard squelch (also called
CTCSS/DCS signaling) can be programmed on each
conventional analog transmit and receive channel in
any order desired. The reverse burst and turn-off code
are always transmitted and also detected on channels
programmed with Call Guard squelch.
The Call Guard squelch feature eliminates
distracting messages intended for others using the
channel. This is done by using a subaudible tone or
digital code to control the squelch. This tone or code is
unique to a user or a group on that channel. This tone
or code is transmitted with the voice signal but is not
heard because it is in the subaudible range and is atten-
uated by a filter. Call Guard squelch must be used in
both the transmitting and receiving transceiver to be
functional.
4.5.2 CALL GUARD SQUELCH ENABLE/
DISABLE
The SEL SQ option switch (if programmed) can
be used to disable receive Call Guard squelch on
analog channels or group ID code detect on P25 chan-
nels. When selective squelch is disabled, “NORMAL”
is flashed in the display, and when it is enabled,
“SELECTIVE” is flashed.
When “Normal” is selected, the receiver
unsquelches only if a carrier is detected, and scanning
and P25 NAC detection are not disabled. The selected
mode remains in effect until it is manually changed.
Selecting another channel or cycling power does not
reselect a default condition.
4.5.3 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
