GETTING FAMILIAR
BASIC OPERATION
-
Indicator
Indicator turns red when transmitting, and it turns green when receiving -
Channel Knob
Rotate the knob to select the channel 1 to channel 16, counterclockwise rotate to decrease the value of channel name, clockwise rotate to increase the value of channel name -
Power Knob/volume Knob
Clockwise rotate to turn on the radio, and counterclockwise rotate to turn off the radio. Rotate the knob can adjust the volume. -
PTT switch
Press PTT switch and then talk to the microphone, the indicator light turns red, if the channel does not have transmitting frequency, a “DU DU” tone sounds, and indicator light turns red. Release PTT switch to receive, it lights green when there is signal. -
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 radios speaker 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 programming software. Level 0 to 9 can be selected. 0 is the lowest level. -
Monitor
Press the squelch button to monitor different DCS calls at the same frequency. or press to press the button to listen when the signal strength does not reach the threshold. -
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 if continuous transmission. If the transmitting time exceeds the TOT pre—set time, the radio will sounds “DU” and stops transmit, release the “PTT” key to back to receive status and stop sound “DU” -
Scan
When the current channel is channel 16, the radio will will automatically detect the 16 channels which defined as scan. When the channel which is be scanned has signal, the radio will stop in the channel to communication Notice:
A. When the scannable channels is less than 2 channels, radio can’ t go to scan
B. When the radio is stopping in the channel which has signal, after the signal disappears 10s, the radio will scans the next channel
C. If radio do not want to scan, please choose the “No” in the “Scan Add” for every channel -
English voice prompt
The voice prompt can be selected ” English/None” through the programming software. -
Battery save function
This function can be set by the software Turn on this function can make the standby time more longer. -
Low battery alert
Notice:
when the voltage is lower than a certain level,if the voice selection is turned off, the sound of “DuDu” will appear every 15 seconds. If the voice is on, it will prompt “please charge.’ If the voice choice of Chinese or English, press PTT key or Vox transmission is invalid and the spund of ‘please charge’ will still prompt, at the same time, the sound “Di’ will ring until PTT release or Vox end. -
Busy channel lock
If the busy lock is set, press PTT after receiving the signal to prohibit transmission and sound “Di” is ringing until PTT release. -
Wide/narrow bandwidth select
The default is wide band, you can select the wide band or narrow band through the programming software -
VOX
Speak to the microphone in normal voice to transmit, no need to press PTT key, turn VOX on /off through the software. A: when VOX is on in your working channel. Speak to the microphone directly, it will transmits 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 gain for the radio to identify voice volume. If the microphone is too sensitive, the noise around radio will start transmit—ting If the microphone is not sensitive, the radio can not collect your voice, please adjust VOX level well to guarantee smooth communications. -
Scrambler
We can use programming software to turn on or off the function of scrambler. Scrambling is one of the methods of information encryption. Scrambler is achieved through cepstrum to complete the goal of change of transportation spectrum. After receiving and releasing the signal, it is restored to achieve the effect of secrecy. Each channel can select the scramble solely. -
CTCSS/DCS
You can set the CTCSSQT / DCSDQT via programming software. After setting the CTCSS or DCS, the squelch can only be turned on when the channel receiving the same CTCSS or DCS. If the same channel uses different QT / DOT for calling, the squelch cannot be turned on, the lights in green. -
Programming protect
Enter the programming software interface, password box will appear (pass—word default is empty) , Tick the new password, the new password will be changed from the original gray into white editable state, fill in the password and click, password set successfully. -
Special signal
This function occurs when there is DCS on the current channel, the purpose is to make the radio under the same group of DCS unable to hear the call content, to achieve the function of encryption.
