Function and Operation

Transmitting Signal
- Press [PTT-1]or[PTT-2]to transmit signals, icon ⑰turns red, and hand-mic light turns grren.
- Press [PTT-1]to transmit main working frequency signals, press [PTT-2]totransmit B band frequency signals.
Receiving Signal
When the device receives same frequency signal with current working channel and the CTCSS matches with each other’s, the radio will receive and send out the voice, and the icon ⑰ turns blue. If A band receives signals, hand-mic light turns green, while B band receives signals, hand-mic lights turns blue.
Working Mode Switching
Short press 【#】 button to change the working mode to VFO frequency mode or Channel MODE. When it is changed to VFO frequency mode, the icon ⑭ will show up as VHF; When it is changed to channel mode,the icon ⑭ will show up as channel number.
Display Mode Switching
Short press 【EXIT】 key to turn on/off dual-band display. When turn off dual- band display, the sub-frequency area will show are as system time.
Frequency Changing and Repeater Frequency Setting
While under VFO mode, input frequencies manually via keypads, input 6 digits, the inputting is done.After this ,the input frequencies will be set to receiving and transmitting frequencies. If need to use repeater to relay the signals, set the TX frequencies according to the repeater frequency table.Operation：Under VFO mode, long press 【1】 button, the frequency turns red, the input function actives , and input 6 digits, so the inputting is done automatically. The input frequencies will set to TX frequencies. Long press 【#】to exit TX frequency setting. Once the inputting is done , please enter MENU list Save CH to save frequency to appointed channel. Short press 【▲】/【▼】can switch preset working frequencies.Long press 【▲】/【▼】is fast switching function.
Channel Switching
Under channel mode status, input channel number via keypads to switch to appointed channel directly .Short press 【▲】/【▼】to switch to working channels one by one. Long press 【▲】/【▼】is fast switching function.
Air Band Receiving When the working frequency is set within the range of 108-136MHz, the device enters aviation frequency receiving mode.
The device is not allowed to transmit signals under aviation frequency band status.
Frequency Detecting and Decoding （One-click Decoding）
【P1】/【P2】/【P3】is set to Freq Detect, and press these definable buttons while it is under standby status. Then the device begins to detecting and decoding. This function cannot detect CTCSS and anti-decoded radios.Press 【PTT】button to exit.
If the frequencies are changing constantly before detecting actives, which means the nearby electromagnetic environment is complicated, in order to avoid strong electromagnetic interference,please choose proper detecting place. After detecting is done, press 【MENU】to save the detected frequency and CTCSS/DCS to current channel, and press 【PTT】to exit, press 【EXIT】to re- detect. If detecting result is standard CTCSS/DCS, it will show up as standard CTCSS/DCS. If the result is non-standard CTCSS/DCS,it will show up as “23b”or “24b” plus a series of digits. After saving, if you want to check the result, please check Menu List Mute Code.
