Operation Guide
Power ON / OFF
Rotate the Power / Volume knob clockwise to switch power
ON. When the click sound of switch and the melody is heard,
the transceiver is powered.
Rotate the Power / Volume knob anticlockwise to switch the
power OFF. When the click sound of switch is heard, the
transceiver's power is turned off.
Transmitting / Receiving
Rotate the Channel knob to the desired channel, press and hold
PTT button. The LED lamp turns red during transmission.
Release PTT button for the transceiver for receiving. During
receiving, LED light turns to green.
※Keep about 5~10cm from microphone area when speaking
slowly and clearly.

Scan Channels
To activate this function, need to assign “ Normal SCAN ” in
programming key setting.
Long press defined key enables start or stop scanning.
During programming, assign desired channels as " Scan CH".
EX: If channels CH1, CH2, CH5, CH9, CH12 are assigned as "
Scan CH", these channels will be scanned in this sequence
continuously till a busy channel is found.
Transceiver will stay on that busy channel for reception or to
transmit and according to "SCAN setting" (BR/TR) to decide on
when can again go on scanning. BR: Till signal disappears for 3
seconds to continue scanning. TR: Staying on the busy channel
exceed setting (3/5/10sec.), transceiver will continue scanning
no matter the signal disappears or not. While there is no signal
and if [PTT] is pushed, transmission is done from self original
channel.
If scanned-out the signal, transmission is done from busy

4
channel. It will again go on scanning after 5 seconds at the end
of reception or radio-communication.
※When scanning, monitor the current channel if press
[Monitoring]. It will again go on scanning after releasing
[Monitoring] 5 seconds.
※In the case of no signal or press the [PTT] or [Monitoring],
LED lamp will be flashing green to indicate in scanning.
※VOX is invalid, when scan in progress.
※This function is not allowed at the [CTCSS/DCS OFF] / [Talk
around] / [TX power adjustment].
Priority Channel Scanning
To activate this function, need to assign “ Pri. SCAN ” in
programming key setting.
Long press defined key enables start or stop scanning.
During programming, assign a channel as " PRI.CH " and "
Scan CH ". Transceiver will scan these channels
interchangeably. Ex: If channel 1 is assigned to be "PRI.CH"
and CH1, CH2, CH5, CH6 assigned to be "Scan CH ", scan
sequence will be CH1(P), CH1, CH1(P), CH2 , CH1(P),CH5,
CH1(P),CH6, CH1(P).
Transceiver will stay on that busy channel for reception or to
transmit and according to " SCAN setting " (BR / TR) to decide
on when can again go on scanning. BR: Till signal disappears
for 3 seconds to continue scanning. TR: Staying on the busy
channel exceed setting (3 / 5 / 10sec.), transceiver will continue
scanning no matter the signal disappears or not.
※Pri. channel is not supported TR SCAN setting.

5
If scanned-out channel is not priority channel, transceiver will
leave it for 3 sec. and will stay standby on priority channel to
check if there is any signal. It will change to " SCAN CH " after 3
sec. from the end of reception or radio-communication. While
there is no signal and if [PTT] is pushed, transmission is done
from priority channel.
If scanned-out the signal, transmission is done from busy
channel. It will again go on scanning after 5 seconds at the end
of reception or radio-communication.
※W hen scanning, monitor the current channel if press
[Monitoring]. It will again go on scanning after releasing
[Monitoring] 5 seconds.
※In the case of no signal or press the [PTT] or [Monitoring],
LED lamp will be flashing green to indicate in scanning.
※VOX is invalid, when scan in progress.
※This function is not allowed at the [CTCSS / DCS OFF] / [Talk
around] / [TX power adjustment].
VOX ON / OFF
To activate this function, press and hold PTT and push [P0]
simultaneously. To deactivate, repeat the same procedure. A
ding-dong melody will be heard at the end of activation and
deactivation of VOX.
※While VOX is enabled, press of [PTT] is no longer required
during transmission. Just talk into the microphone area with
appropriate sound (depending on VOX sensitivity).

6
Sensitivity Adjustment of VOX
Press and hold P0 and simultaneously turn on the power and
wait for 3 seconds to activate VOX adjustment mode.
(Following 3 beeps, and the red LED lamp will flash three times)
Use Channel knob to select 1~16 sensitivity level of VOX (1
being the highest, 16 being the lowest in sensitivity.) Talk to
MIC speaker to find suitable sensitivity level (VOX will send out
a short beep at the beginning of operation, the LED lamp turns
red without transmitting.) When desired sensitivity is reached,
press and hold [P0]. One beep can be heard when transceiver
completes setting and exists VOX adjustment mode.
SOS (Emergency) Channel
To activate this function, need to assign “ TO SOS CH ” in
programming key setting.
Long press defined key enables to switch SOS channel. Repeat
the same procedure to switch the current channel where the
