BASIC OPERATION

1. The indicator turns red when transmitting, and it turns green when receiving

2. Channel Knob
   Rotate the knob to select channel 1 to channel 16, counterclockwise rotate to decrease the value of channel name, and clockwise rotate to increase the value of channel name

3. Power KnobNolume Knob
   Clockwise rotate to turn on the radio, and counterclockwise rotate to turn off the radio. Rotating the knob can adjust the volume.

4. PTT switch
   Press the PTT switch and then talk to the microphone, the indicator light turns red, if the channel does not have to transmit frequency, a “DU DU” tone sounds, and the indicator light turns red. Release the PTT switch to receive, it lights green when there is a signal.

5. 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 capacity will be weaker. The default setting of the squelch level is 5, you can adjust it through the menu “Squelch level” of the “Optional Features” in the programming software. Levels 0 to 9 can be selected. 0 is the lowest level.

6. 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.

7. 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. If the transmitting time exceeds the TOT preset time, the radio will sound “DU” and stops transmitting, release the “PTT” key back to receive status, and stop sounding “DU”

8. Scan
   When the current channel is channel 16, the radio will automatically detect the 16 channels which are defined as scans. When the channel which is being scanned has a signal, the radio will stop in the channel to communicate Notice:
   A. When the scannable channels is less than 2 channels, the radio can’t go to scan
   B. When the radio is stopping in the channel which has a signal after the signal disappears 10s, the radio will scan the next channel
   C. If the radio does not want to scan, please choose the “No” in the “Scan Add” for every channel

9. English voice prompt
   The voice prompt can be selected English/None” through the programming software.

10. Battery save function
    This function can be set by the software Turn on this function can make the standby time longer.

11. 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 the PTT key or Vox transmission is invalid and the sound of ‘please charge’ will still prompt, at the same time, the sound “Di” will ring until PTT release or Vox end.

12. Busy channel lock
    If the busy lock is set, press PTT after receiving the signal to prohibit transmission, and the sound “Di” rings until PTT is released.

13. Wide/narrow bandwidth select
    The default is wide band, you can select the wide band or narrow band through the programming software

14. VOX
    Speak to the microphone in a normal voice to transmit, no need to press the PTT key, or turn VOX on /off through the software.
    A: 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 to Receive
    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 the radio will start transmitting—ting If the microphone is not sensitive, the radio can not collect your voice, please adjust the VOX level well to guarantee smooth communications.

15. Scrambler
    We can use programming software to turn on or off the function of a scrambler. Scrambling is one of the methods of information encryption. Scrambler is achieved through cepstrum to complete the goal of changing 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.

16. 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 receives the same CTCSS or DCS. If the same channel uses differ—ent QT / DOT for calling, the squelch cannot be turned on, and the lights are in green.

17. Programming protects
    Enter the programming software interface, the password box will appear (pass—word default is empty), Tick the new password, and the new password will be changed from the original gray into the white editable state, fill in the password and click, password set successfully.

18. 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.
