5 BATTERY CHARGING

■Battery charging

Prior to using the transceiver for the ﬁrst time, the battery pack 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)

-The Li-Ion battery functions within –20°C to +60°C (–4°F to +140°F)

•Use the specified chargers (BC-152, BC-119N and BC-121N). NEVER use another manufacturer’s charger.

•Use the optional AC adapter (BC-147A/E) for the BC-152.

•NEVER use another manufacturer’s AC adapter.

Recommendation:

Charge the supplied battery pack for a maximum of up to 10 hours. Li-Ion batteries are different from Ni-Cd batteries in that it is not necessary to completely charge and discharge them to prolong the battery life. Therefore, charging the battery in inter- vals, and not for extended periods is recommended.

BATTERY CHARGING 5

■ Caution

CAUTION! NEVER insert battery pack/transceiver (with the bat- tery pack attached) with wet or soiled into the charger. This may re- sult in corrosion of the charger terminals or damage to the charger. The charger is not waterproof and water can easily get into it.

NEVER incinerate used battery packs. Internal battery gas may	5
cause an explosion.
NEVER immerse the battery pack in water. If the battery pack be-
comes wet, be sure to wipe it dry immediately (particularly the bat-
tery terminals) BEFORE attaching it to the transceiver. Otherwise,
the terminals will become corroded, or cause connection failure,
etc.
NEVER short the terminals of the battery pack. Also, current may
ﬂow into nearby metal objects, such as a necklace, etc. Therefore,
be careful when carrying with, or placing near metal objects, carry-
ing in handbags, etc.
AVOID leaving the battery pack in a fully charged, or completely
discharged condition for long time. It causes shorter battery life. In
case of leaving the battery pack unused for a long time, it must be
kept safely after discharge, or use the battery until the battery indi-
cator starts blinking, then remove it from the transceiver.
If your battery pack seems to have no capacity even after being
charged, completely discharge it by leaving the power ON
overnight. Then, fully charge the battery pack again. If the battery
pack still does not retain a charge (or very little), a new battery pack
must be purchased.
