I BEFORE ENTERING THE ADJUSTMENT MODE
• Cloning the adjustment frequency 156.800 MHz on the programmable CH.
(No select POC function POC ON on the adjustment frequency. )
I ENTERING THE ADJUSTMENT MODE
• Push and hold the [H/L] key and [PTT] switch, and then turn power ON.
I OPERATING IN THE ADJUSTMENT MODE
• Change adjustment items:
• Change adjustment values:
I EXITING THE ADJUSTMENT MODE
When adjustment is finished, need to do follow operation to cancel the adjustment mode. Otherwise, the transceiver does not
work properly.
• Turn power OFF.
• Push and hold the [H/L] key and [PTT] switch, and then turn power ON.
• DC POWER CABLE CONNECTION
