directly through UART port. During cloning, LED of source radio flashes red and that of

target radio flashes green. A BEEP sounds when cloning is complete.

PC Mode

1) Connect the radio with a PC by programming cable. And then turn the power on. The radio

enters PC mode after two seconds and LED glows orange.

2) Data can be transferred between MCU and PC via UART port. If data is transferred to the

radio from PC, it can be programmed into the EEPROM by MCU and LED flashes red during

data transfer. If data is transferred to PC from the radio, MCU sends the EEPROM data to PC

and LED flashes green during data transfer.

3) You can update software and provide second development feature for the user via PC

update programme. LED flashes orange during programme download.

4) To exit PC mode and enter conventional mode or other mode, turn on the power again.

All Reset Mode

Turn on the power while holding down PTT and programmable key A simultaneously (or short
