9 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. Cautions NEVER incinerate used battery packs. Internal battery gas may cause an explosion. 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 is functioning within -20°C to +60°C (-4°F to +140°F) • Use the specified chargers (BC-119N, BC-121N and BC152). NEVER use another manufacturer's charger. • Use the supplied AC adapter (BC-147A/E) for BC-152. NEVER use another manufacturer's AC adapter. 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. Recommendation: Charge the supplied battery pack for a maximum of up to 10 hours. Li-Ion batteries are different from NiCd batteries in that it is not necessary to completely charge and discharge them to prolong the battery life. Therefore, charging the battery in intervals, and not for extended periods is recommended. 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. 22

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 con-
nection failure, etc.
NEVER
short the terminals of the battery pack. Also, current
may
fl
ow 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 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.
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 intervals, and not
for extended periods is recommended.
