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 is functioning within –20°C to +60°C
(–4°F to +140°F)
• Use the specified chargers (BC-119N, BC-121N and BC-
152). NEVER use another manufacturer’s charger.
• Use the supplied AC adapter (BC-147A/E) for BC-152.
NEVER use another manufacturer’s AC adapter.
■ 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 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 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.
