Resume Factory Default
Once transceiver works abnormally for wrong operations or wrong
programming, users can start this function to resume all functions
and channels as Factory Default.
Press [PTT] and [PF1] key synchronously to switch on transceiver.
Holding the two keys for more than 1 second, the transceiver will
resume Factory Default after announcing current channel number.
Maintaining and Cleaning
Cover the jack with its opercula when the transceiver is not at use.
After long-time use of the transceiver, keys, control buttons and
housing would become dirty. Then, neutral detergent (no corrosive
chemical agent) and wet cloth can be used to clean them.
