BATTERY CHARGING
Battery charging
Prior to using the transceiver for the rst time, the Ni-Cd bat-
teries must be fully charged for optimum life and operation.
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.
CAUTION: To avoid damage to the transceiver, turn it OFF
while charging.
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
ow 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.
