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
