Main Functions

Beat Frequency & Reverse Frequency

Press the corresponding function key to activate beat frequency or reverse frequency instead of re-programming parameters to change RX and TX between point- to- point communication and under repeater communication.

Frequency Scan/Channel Scan

Multi-mode scan is convenient for team leader to monitor the on-site situations.

PTT ID Encode (DTMF) /Decode

It provides identification of radio to control center or radio with DTMF decode, it is quite useful for communication management. ENI will be sent when you press or release PTT button if this function is on.

128 Channels

A large channel capacity allows more flexible assignment among different user groups.


To hear a weak signal, press MONI key. And it helps adjust volume when no signal is received.


BCL is used to prevent the interference with the on-going conversation.

5 Signaling

CTCSS, CDCSS, DTMF, 2-Tone and 5-Tone can be used in selective call/group call/remote kill/remote control function.

Emergency Alert

In case of emergencies or unexpected events, the radio will automatically send alarm immediately while the alarm button is pressed. In addition, the background or ID code can be secretly sent out to notify your partners.

Squelch Tail Elimination

The function will minimize the annoying audio outputs that occur at the receiver on completion of a transmission.

Wired Clone

To quickly set the parameters on a radio, you can clone the radio data from another radio with the supplied data cable, saving the time of parameter setting.

PC Programmable

Frequency and various features can be set by PC programming software.
