■Selecting a Group or Channel
Rotate the Rotary encoder (or press the keys
programmed as Group Up/Down or Channel Up/
Down) to choose your desired group or channel.
Clockwise increases the number and counter-
clockwise decreases it.
• If a group or channel has not been programmed, it
cannot be used.
12
■Adjusting the Squelch Level
Squelch is used to silence the speaker when no
signals are present. When squelch is turned OFF,
you will hear background noise from the speaker.
When it is ON, you will not hear background noise.
The squelch level you select determines when
squelch will turn OFF and ON. If you select a
squelch level that is too high, you will not hear
weaker signals. If you select a squelch level that is
too low, you will hear background noise between
signals.
To adjust the squelch:
1Press and hold the Side 2 key, then press the >
key.
• “SQL” and the current squelch level appear.
2Rotate the Rotary encoder to select a squelch
level from 0 ~ 9.
• Clockwise increases the squelch level and
counterclockwise decreases it.
3Press any key other than the key programmed as
Lamp to complete the setting.
• Normal operation is restored.
13
■Placing a Call
1Make sure no parties are currently transmitting on
your selected channel.
2Press the PTT switch and speak into the
microphone in your normal speaking voice.
•For best sound quality at the receiving station, hold
the microphone approximately 1.5 inches
(3 ~ 4 cm) from your mouth.
3Release the PTT switch to receive.
■Receiving a Call
Your dealer may have programmed QT or DQT
signalling on your transceiver. If your selected
channel is programmed with one of these features,
you will hear calls only when another party in your
system makes a call. All other calls will not be
heard.
If your selected channel is not set up with QT or
DQT, you will hear calls made by any party (not just
those in your system).
14
CHANNEL SCAN
Scan is useful for monitoring signals on the channels
programmed on the transceiver. When scanning, the
transceiver checks for a signal on each channel, and
only stops on a channel if a signal is present.
The transceiver will remain on a busy channel until the
signal is no longer present. Your dealer programs the
delay time between signal drop-out and scan
resumption. If a signal is received during the delay
time, the transceiver will remain on the same channel.
Note:
◆
You can only use Scan if your dealer has programmed at least 2
channels on the transceiver. Also, there must be at least 2 channels
not locked out of Scan.
◆
Ask your dealer for an explanation on how Channel Scan functions
when using Code Squelch, Selective Call, or 2-Tone signalling.
To start scanning, press the key programmed as Scan.
• Scanning starts from the current channel and ascends
through the channel numbers.
• The SCN icon and “SCAN” appear on the display.
To end Scan, press the Scan key again.
15
■Priority Scan
If your dealer set up a priority channel on your
transceiver, the transceiver will continuously monitor
that channel while receiving a signal on another
channel. When a signal is received on the Priority
channel, the transceiver immediately switches to that
channel.
• “P” appears on the display.
The transceiver will remain on the Priority channel
until the signal drops out. Your dealer programs the
delay time between signal drop-out and scan
resumption.
■Channel Lockout
If programmed by your dealer, you can select
channels to lock out of the scanning sequence.
Perform the following steps while not in Scan mode.
1Rotate the Rotary encoder to select the channel
you want to lock out of Scan.
2Press the key programmed as Scan Del/Add.
• Each press of Scan Del/Add toggles the lockout
status of the selected channel ON and OFF.
• Channels that are included in Scan are represented
by an “A” on the display. Channels locked out of
Scan do not have an “A” on the display.
■Revert Channel
During Scan, pressing the PTT switch to transmit will
cause the transceiver to select the revert channel.
Your dealer programs the Revert channel for your
transceiver. Consult your dealer for details.

CODE SQUELCH
Code Squelch is enabled or disabled by your dealer.
This function turns the transceiver squelch OFF only
when it receives the DTMF code that has been set up in
your transceiver. Transceivers that do not transmit the
correct code will not be heard. Consequently, you can
communicate with a specific party without listening to
other parties using the same channel.
Your dealer may also activate Group Call for your
transceiver. This is useful when you want to pass
information to a number of units in a fleet. Ask your
dealer for details.
Note: Code Squelch cannot be used on channels programmed with
Selective Call or 2-Tone Signalling.
■Receiving
When you receive a signal containing the correct
code, squelch turns OFF and you will hear the call.
• “CALL” appears on the display and the LED indicator
flashes orange.
• To mute the speaker after squelch turns OFF, press the
key programmed as Monitor.
• Your dealer can program squelch to automatically turn
back ON after a specific time period elapses.
• If Transpond for Code Squelch is programmed, an
acknowledgment signal is returned to the calling
station. Transpond does not function when you are
called with a Group code. Transpond for Selective Call
can send an alert tone, a transceiver ID code, or a
code stored in memory location 1.
• If Tone Alert for Code Squelch is programmed, an alert
tone will sound when the correct code is received.
20
■Transmitting
1Press and hold the PTT switch.
2Enter the code of the transceiver you want to call
or enter a Group code on the keypad.
• If desired, you can send codes the same way you
make DTMF calls {page 16}. Both manual methods
can be used or you can store codes in memory,
then dial them from a memory location.
• “CALL” appears on the display and the LED
indicator lights red.
3Use the transceiver the same as in a regular call;
press the PTT switch to transmit and release it to
receive.
• The called transceiver’s squelch will turn OFF while
you are transmitting. After you stop transmitting,
the squelch will turn back ON after a pre-set time
period elapses. This time period is programmed by
your dealer.
• When you release the PTT switch, squelch turns
OFF and the LED indicator flashes orange. When
you receive a signal, the LED indicator lights green.
When the signal drops out, the LED indicator
flashes orange again. If no signal is received for a
pre-determined time, squelch turns back ON.
• Pressing the key programmed as Monitor at any
time will turn the squelch back ON.
21
SELECTIVE CALL
Selective Call is enabled or disabled by your dealer.
This function is similar to Code Squelch {page 19}. The
differences from Code Squelch are:
• You can send or receive message codes containing a
maximum of 5 digits.
• Selective Call turns the squelch OFF only when the
transceiver receives a predetermined DTMF code in the
correct sequence:
1) A 3-digit ID code
2) A 1-digit Intermediate code
3) A message code (up to 5 digits)
Your dealer may also activate Group Call for your
transceiver. This is useful when you want to pass
information to a number of units in a fleet. Ask your
dealer for details.
Note: Selective Call cannot be used on channels programmed with
Code Squelch or 2-Tone Signalling.
22
■Receiving
When you receive the correct ID and Intermediate
codes, squelch turns OFF and you will hear the call.
If a message code is also received, the message
appears on the display
• “CALL” appears on the display and the LED indicator
flashes orange.
• When you receive a call with your ID code, “C”
appears on the display (i.e.- C 12345).
• When you receive a call wih your Group code, “A”
appears on the display (i.e.- A 12345).
• When no message is received, “NO DATA” appears on
the display.
• You can clear a message by pressing any key other
than the key programmed as Lamp.
• To mute the speaker after squelch turns OFF, press
the key programmed as Monitor.
• Your dealer can program squelch to automatically turn
back ON after a specific time period elapses.
• If Transpond for Selective Call is programmed, an
acknowledgment signal is returned to the calling
station. Transpond does not function when you are
called with a Group code. Transpond for Selective
Call can send an alert tone, a transceiver ID code, or a
code stored in memory location 1.
• If Tone Alert for Selective Call is programmed, an alert
tone will sound when the correct code is received.
23
■Transmitting
1Press and hold the PTT switch.
2Enter the code of the transceiver you want to call
or enter a Group code on the keypad.
• Be sure to enter the ID or Group code, followed by
the Intermediate code of the transceiver you want

2-TONE SIGNALLING
2-Tone Signalling is enabled or disabled by your dealer.
This function turns the transceiver squelch OFF only
when it receives the 2-tone signal that has been set up
in your transceiver. Transceivers that do not transmit
the correct tones will not be heard.
Your dealer may also activate Group Call for your
transceiver. Ask your dealer for details.
■Receiving
When you receive a signal containing the correct
tones, squelch turns OFF and you will hear the call.
• “CALL” appears on the display and the LED indicator
flashes orange.
• To mute the speaker after squelch turns OFF, press the
key programmed as Monitor.
• Your dealer can program squelch to automatically turn
back ON after a specific time period elapses.
• If Transpond for 2-Tone Signalling is programmed, an
acknowledgment signal is returned to the calling
station. Transpond for 2-Tone Signalling can transmit
an alert tone only.
• If Tone Alert for Code Squelch is programmed, an alert
tone will sound when the correct tones are received.
25
■Transmitting
1Press the key programmed as TX Code Select.
• A 2-Tone code appears on the display.
2Rotate the Rotary encoder to select your desired
2-Tone code.
3Use the transceiver the same as in a regular call;
press the PTT switch to transmit and release it to
receive.
• When you release the PTT switch, squelch turns
OFF and the LED indicator flashes orange. When
you receive a signal, the LED indicator lights green.
When the signal drops out, the LED indicator
flashes orange again. If no signal is received for a
pre-determined time, squelch turns back ON.
• Pressing the key programmed as Monitor at any
time will turn the squelch back ON.

AUXILIARY FUNCTIONS
■Selecting an Output Power
Each channel is programmed with either high or low
output power by your dealer. You can change the
output power of only channels programmed as high.
When you can reliably communicate with other
parties without using high power, select low power by
pressing the key programmed as RF Power Lo.
Each time you press RF Power Lo, the output power
toggles between high and low.
• Using low power conserves battery power and reduces
the risk of interfering with other communications.
• The “LO” icon appears when you are using low power.
Note:
◆
Pressing RF Power Lo while using a channel programmed with
low power causes an error tone to sound.
◆
When changing a channel from high power to low power, all
channels programmed with high power are changed to low.
■Time-out Timer (TOT)
The purpose of the Time-out Timer is to prevent any
caller from using a channel for an extended period of
time.
If you continuously transmit for a period of time that
exceeds the programmed time, the transceiver will
stop transmitting and an alert tone will sound. To
stop the tone, release the PTT switch.
Your dealer can program a warning function to alert
you before the TOT expires. Continuously
transmitting for the time specified by your dealer will
cause the warning tone to sound.
27
■Busy Channel Lockout (BCL)
The Busy Channel Lockout feature is activated or
deactivated by your dealer.
When activated, BCL prevents you from interfering
with other parties who may be using the same
channel that you selected. Pressing the PTT switch
while the channel is in use will cause your
transceiver to emit an alert tone and transmission will
be inhibited (you cannot transmit). Release the PTT
switch to stop the tone and return to receive mode.
■Talk-Around
You may occasionally experience an interruption in
service (due to a power failure, etc.). During such an
occurence, you can continue communication by
using the Talk-Around feature, if it has been
programmed by your dealer. Talk-Around allows you
to communicate directly with other transceivers,
without the use of a repeater. However, if the station
you want to contact is too far away, or there are
geographical obstacles in the way, you may not be
able to contact the station.
Toggle Talk-Around ON and OFF by pressing the key
programmed as Talk-Around.
• “T” or “TA” appears on the display while Talk-Around is
active.
• When using Talk-Around, the “receive” frequency is
used for both transmission and reception, and the QT/
DQT “decode” signalling is used for both encoding and
decoding.
28
■Reverse
Your dealer may have programmed the Reverse
function instead of the Talk-Around function.
When using Reverse, the transmit and receive
frequencies are swapped. This means that you will
transmit on the “receive” frequency and receive on
the “transmit” frequency. The QT/DQT encoding and
decoding signals are also reversed, meaning that
transmitted signals are encoded using the “decode”
signal, and received signals are decoded using the
“encode” signal.
Toggle Reverse ON and OFF by pressing the key
programmed as Reverse.
• “R” or “RE” appears on the display while Reverse is
active.
■Battery Voltage Level
While transmitting, the transceiver automatically
checks the battery voltage level. When the voltage
level becomes low, the LED indicator flashes red.
When a tone sounds, transmission stops. Recharge
or replace the battery pack at this time.
■Lamp
Press the key programmed as Lamp to toggle the
display backlight ON or OFF. The backlight
automatically turns OFF approximately 5 seconds
after it is switched ON.
Press any key other than Lamp while the backlight is
ON to reset the 5 second timer. The timer will reset
and the backlight will remain on for 5 seconds.
29
■Monitor
Your dealer can program a key with the Monitor
function one of four ways:
APress and hold the Monitor key to hear background
noise. Release the key to return to normal operation.
BMomentarily press the Monitor key to hear
background noise. Press the key again to return to
normal operation.
CPress and hold the Monitor key to deactivate QT,
DQT, or 2-Tone signalling. Release the key to return to
normal operation.
DMomentarily press the Monitor key to deactivate QT,
DQT, or 2-Tone signalling. Press the key again to
return to normal operation.
You can use the Monitor key to listen to weak
signals that you cannot hear during normal operation
and to adjust the volume when no signals are
present on your selected channel.
■Beginning/ End of Transmission Signal
Your dealer can enable or disable the Beginning/
End of Transmission identification signals. These
signals are used to access and release some
repeaters and telephone systems.
To send a Beginning of Transmission signal, either
press the PTT switch, or press the key two times.
To send an End of Transmission signal, either
release the PTT switch or press the key followed
by the # key.
• Ask your dealer which method has been activated on
your transceiver.
