FM Transceiver
5
NOTE: when charging a power-on radio equipped with battery, the indicating lamp will not turn
into green to show the fully charged status. Only when the transceiver is switched off, the lamp can
indicate normally. The radio consumers 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 in constant
voltage and fail to indicate correctly whether the battery has been fully charged.
