Main Functions

CTCSS/CDCSS encode & decode can prevent conversation from any unwanted receiver.
25.0 kHz/ 12.5 kHz Switch
Different channel spacing 25.0kHz /12.5kHz are optional to comply with the regulations of different countries.
Priority Channel Scan
Priority scan permits scanning of all channels while a priority channel is being monitored simultaneously. And this function is still activated even while user is receiving a call from another non-priority channel.
Low Battery Alert
This feature can remind users to replace or charge the battery when the battery power is low.
This feature enables user to hear weak signals. User can adjust volume by pressing MONI key when no signals are received.
Precision Knob Design
Fully considering of the practical operating scene, the switch and knob are carefully designed. And users can clearly know the channel position through touching even with protective gloves on.
Busy Channel Lockout (BCL)
BCL is used to protect the on-going conversation from unwanted interference.
The feature allows for more efficient use of channels by limiting the amount of time of each transmission. Also, it effectively avoids radio damage because of long-time 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.
Beat Shift
Avoid the interference of dominant frequency on the performance of the radio.
Squelch (1~9 selectable)
It can minimize interference from undesired weak signals and enable weak signals to be heard.
Squelch Tail Elimination
The function will minimize the annoying audio outputs that occur at the receiver during a transmission.
PC Programming
Frequency and various features can be set by PC programming software.
