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 t he
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.
Volume Adjust ment
- Rotate the Power / Volume knob slowly to avoid outburst of
sound harmful to ears. Adjust volume to an appropriate level.
- Rotate the Power / Volume knob in clockwise direction to
increase volume. Rotate Power/Volume knob anticlockwise to
decrease volume.
※Caution: For external mic / ear user, adjust volume starting
from the lowest level.

- If no mark the option "Do not lock the channel knob when the
key is locked" when programming, it will lock all keypads and
unable to rotate channel knob. Once adjust channel knob, the
speaker sounds beeps continuously and LED stays on red
lamp.
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
channel. It will again go on scanning after 5 seconds at t he 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].

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 t o
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.
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. W hile
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 t he 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.
※W hile VOX is enabled, press of [PTT] is no longer required
during transmission. Just talk into the microphone area with

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 sensiti vity.) 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
channel knob located.
※In advance to assign the desired channel to SOS channel
when programming.
