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:
0°C to +45°C
- The Li-Ion battery is functioning within –10°C to +60°C
• Use the specified chargers (BC-119N, BC-121N and
BC-152). NEVER use another manufacturer's charger.
• Use the supplied AC adapter (BC-147E) for 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 com-
pletely charge and discharge them to prolong the
battery life. Therefore, charging the battery in inter-
vals, and not for extended periods is recommended.

■ Cautions

NEVER
incinerate used battery packs. Internal battery gas
may cause an explosion.
NEVER
immerse the battery pack in water. If the battery
pack becomes wet, be sure to wipe it dry immediately (par-
ticularly the battery 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, cur-
rent may flow into nearby metal objects, such as a necklace,
etc. Therefore, be careful when carrying with, or placing near
metal objects, carrying in handbags, etc.
DO NOT
leave the battery pack in a fully charged, or com-
pletely 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 indicator shows the middle level,
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.
