Charging a 'flat' battery
If the battery is completely 'flat' (without charge) during storage or after a long period of non-activity, it
may fail to recharge or stop charging after 20 minutes. If this happens, disconnect and then
reconnect the charger (or power off the charger, then power on) to reset the battery.
NOTE: Do not charge a flat battery attached to the radio. During charging, the radio
will attempt to power on when the battery charge reaches a certain capacity, which
will continually drain the battery of its charge. Always charge a flat battery with the
radio powered off or using a battery charger.
Fitting the battery
To fit the battery, insert the battery into the battery compartment as shown. Press the battery
downwards until it clicks into position.
Fitting the battery when a belt clip is attached
If a Belt clip or Shirt/Pocket clip is fitted to the radio, lift the Belt clip or Shirt/Pocket clip before
attempting to fit the battery. Do not attempt to insert the battery into the battery compartment
sideways under the clip. This may result in damage to the radio and the belt clip.
Removing the battery
Power off before removing the battery.
