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 +40°C (+32°F to +104°F)
- The Li-ion battery is functioning within –10°C to +60°C
(+14°F to +140°F)
• Use the specified chargers (BC-119N, BC-121N and BC-
152N). NEVER use another manufacturer's charger.
• Use the supplied AC adapter for BC-152N. 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 dis-
charge them to prolong the battery life. Therefore, charg-
ing the battery in intervals, 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 (particularly
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, current
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.
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 indicator shows the middle level,
then remove it from the transceiver.
If your battery pack seems to have no capacity even after
being charged, 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.
