Speak to the microphone directly, it will transmit automatically.
The radio stops transmitting when there is no voice, and waits for receiving.
B: when a headset with a microphone is used.
When VOX is on, you should VOX again for the radio to identify voice volume.lf the microphone is too sensitive, the
noise around radio will start transmitting.
if the microphone is not sensitive, the radio can not collect your voice, Please Adjust voxevel well to guarantee smooth
communications.
English/Chinese /Voice PromptVoice prompt
The default setting is Chinese voice prompt, and you will know the working condition ofthe radio with voice prompt.
1) The voice prompt can be selected "Chinese/English/Tone/OFF" through the menu"Voice/Beep Tone" of the "Optional
Features" in the software for. When choosing"OFF", voice prompt turns off.
2) Channel annunciation: You will get to know the working conditions of current channel which is being operated.
3)Low battery alert: The radio will alert you when the battery capacity reaches theminimum operating voltage.
Low battery prompt
The default setting is Chinese voice prompt. When transmitting or standby, if the battery capacity reaches the
pre-determined low level, the indicator light blinks red, and a low battery alert tone will be heard.
The indicating tone can be "Please change the battery". When the low battery alert occurs,it can not transmit, please
change or charge the battery.
squelch function
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 radios speaker will be higher,and the corresponding communication range will be
further, but the anti-interference capacity will be weaker.
The default setting of squelch level is 5, you can adjust it through the menu "Squelch Level"of the "Optional Features" in
the software for. Level 0 to 9 can be selected.0 is the lowestlevel.
Time out timer (ToT)
The purpose of TOT is to prevent any radio from talking in one channel for a long time,and to prevent the transceiver
from being damaged because of continuous transmission.f the transmitting time exceeds the TOT pre-set time, the
radio will sound "Du".Release
Power protection function
When the radio is in normal use or maintenance, the transmission will be prohibited if the working voltage is beyond the
normal supplying voltage.Lower than 3V or higher than 5v,the transmission will be prohibition. The radio cannot power
on when it is higher than 5V.
CTCSS/DCS
CTCSS and DCS is the sub-audio signaling, to prevent the radio from receiving unwanted signal in the same channel.
When the CTCSS/DCS is set, then within the communication range,you can only receive signals from the same channel
with the same CTCSS/DCS setting. When the CTCSS/DCSS not set, you will get all the signal from the same channel
within the communication range.You can set the CTCSS/DCS through the menu "QT/DQT ENC" or "QT/DQT DEC" of
the Channel information" in the software.
