Basic opeartions
LED indicator
It lights red when transmitting, and lights green when receiving.
Channel-selecting knob
Rotate it to select channel 1-16, clockwise rotation to increase, counter-clockwise rotation to
decrease. An alert tone will sound when an empty channel is selected.
Power/Volume knob
Rotate it by clockwise to power on the radio. To turn off the radio, rotate it by counterclockwise

Side-key
Can be defined in the software as null / VOX/ emergency alarm / scan / busy lock, the default
definition is short press scan switch, long press VOX switch.
Moni switch
Press the button to monitor calls with different mute tones at the same frequency, and also press
to listen when the signal strength does not reach the opening threshold.
Squelch level
The squelch level will determine the signal strength to open the speaker of the radio. If the
squelch level is lower, the background noise of opening the radio's speaker will be higher,
and the corresponding communication range will be further, but the anti-interference
ability will be weaker. The default setting of squelch level is 3, you can adjust it through
the menu "Squelch level" of the "Optional features" in the software, level 0 to 9 can be
selected. 0 is the lowest level.
Time out timer (TOT)
The purpose of TOT is to prevent any radio from talking in one channel for too long, and to
prevent the radio from being damaged due to continuous transmission. If the transmitting time
exceeds the TOT pre-set time, the radio will stop transmission and an alert tone sounds.Release
PTT switch to stop the alert tone, the radio resume to receiving mode.
Scan On/Off
When the radio is set as scan via software, rotate the channel-selecting knob to channel 16, it
will start scanning. It will scan all scannable channels from channel 1 to 16. You can define as
channel added or deleted in software. When there is signal in the scanning channel, it stops in
the channel for talk.
Note:
a. The radio will stay in the channel which has signal, and 15 seconds after the signal disappears,
it will continue scanning.
b. It can not scan when there is less than 2 scannable channels.
VOX
Speak to the microphone in normal voice to transmit directly, no need to press PTT switch.
Side-key can be defined as VOX switches in the software.
1) When VOX is on in your working channel.
Speak to the microphone directly, it will transmit automatically.
The radio stops transmitting when there is no voice, and waits for receiving.
2) When a headset with a microphone is used.
When VOX is on, you should increase the VOX gain for the radio to identify voice volume.
lf microphone is too sensitive, the noise around radio will start transmitting. If microphone is not
sensitive, the radio can not collect your voice.

Please adjust VOX level well to guarantee smooth communications.
Note: When turn on VOX and VOX gain is in high and sensitive level, if connect mic/speaker
with radio, the signal of mic/speaker will probably cause radio transmit. Whether it is in Chinese
or English speech, press and hold the PTT button or VOX are all invalid and issued a "please
change battery" voice prompt, and loud "Di" sound until PTT release or end VOX.
Busy channel lockout(BCLO)
If you set busy channel lockout, press PTT after receiving a signal of prohibiting transmit, and
issue "Di" sound until PTT release.
QT/DQT
You can select the QT/DQT via program software. When a channel has QT/DQT, the speaker
will be turned on when it receives the same QT/DQT. If there is transmitted signal with different
QT/DQT in the same channel, the speaker will not open and indicator light turns green
