OPERATION
To charge a battery (fitted to a portable radio):
(6) Connect the 3,5mm jack plug of the charger to the 3,5mm socket on the top of the radio.
(7) Connect the charger module to the mains power outlet.
(8) Switch on the mains power (if switched).
The battery commences charging.
Note: The radio does not have to be switched on to charge the battery.
The trickle charge power supply uses a positive input on the RxD pin of the Smart interface (on the
portable radio) to power a current limited source feeding the battery, limiting the current to approximately
130mA. This circuit is enabled by the thermistor in the battery pack, so it is inhibited if a battery pack is not
fitted (this is necessary to prevent a voltage at the battery connector which could damage the radio when
no battery is present).
All functions of the portable radio may be used while connected to the power supply. However,
charging is inhibited while transmitting.
