BATTERY INFORMATION
NOTE: When charging a power-on transceiver equipped with battery, the indicating lamp will not
turn into green to show the fully charged status. Only when the transceiver is switched off, can the
lamp indicate normally. The transceiver consumes energy when it is power-on, and the charger can
not detect the voltage when the battery has been fully charged. So the charger will charge battery
constant voltage and fail to indicate correctly whether the battery has been charged fully.
