The ON/OFF SWITCH is located on the battery pack. Sliding this switch up will supply power to the radio from the battery pack. An audible click will be heard and the "ON" indicator will be exposed. When the radio is turned on, it will perform a power-up self test and then resume operation on the previous operating channel as displayed in the LCD.
