Channel Scan
It enables you to set 16 channels for scan function& also enables you set for a priority channel

Computer software Program

The user can set the frequency and other related data through computer software

38 Groups of CTCSS

It enables you to receive signal selectively by different CTCSS tones.

Time-Out Timer(TOT)

TOT will prevent any individual from using a channel for extended period nby setting continuous transmission time.

Busy Channel Lockout

It prevents you from interfering with using channel.

Power Save Function

Power save function deceases the power consumption when no signal is being received and no operation is being performed.
