7 BATTERY CHARGING

■Battery charging

Prior to using the transceiver for the ﬁrst time, the Ni-Cd bat- teries must be fully charged for optimum life and operation.

CAUTION: To avoid damage to the transceiver, turn it OFF while charging.

•Recommended temperature range for charging:

+10°C to +40°C (+50°F to +104°F)

•Use the supplied charger (BC-150) only. NEVER use an other manufactures charger.

NEVER connect DC power to the battery case when in- stalling alkaline batteries. Such a connection will damage the transceiver.

■Battery cautions

NEVER incinerate used Ni-Cd batteries. Internal battery gas may cause an explosion.

NEVER immerse batteries in water. If the battery case be- comes wet, be sure to wipe it dry BEFORE attaching it to the transceiver.

NEVER short terminals of the battery case. Also, current may ﬂow into nearby metal objects so be careful when placing bat- tery cases in handbags, etc.

If your Ni-Cd batteries seem to have no capacity even after being charged, completely discharge them by leaving the power ON overnight. Then, fully charge the Ni-Cd batteries again. If the batteries still do not retain a charge (or very little), new batteries must be purchased.
