Battery caution
R DANGER! Use/Charge the specified Icom batteries only.
Only tested and approved for use with genuine Icom bat-
teries. Fire and/or explosion may occur when a third party
battery pack or counterfeit product is used/charged.
• CAUTION! NEVER short the terminals of the battery pack
(or charging terminals of the transceiver). Also, current may
flow into nearby metal objects such as a necklace, so be
careful when placing battery packs (or the transceiver) in
handbags, etc.
Simply carrying with or placing near metal objects such as a
necklace, etc. causes shorting. This will damage not only
the battery pack, but also the transceiver.
• 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 BEFORE attach-
ing it to the transceiver.
• Clean the battery terminals to avoid rust or poor contact.
• Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.
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 only very little
charge), a new battery pack must be purchased (p. 77).

Charging NOTE
Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and operation.
• Recommended temperature range for charging:
+10°C to +40°C (; +50˚F to 140˚F)
• Use the supplied charger or optional charger (BC-119N/121N/144N
for rapid charging, BC-146 for regular charging) only. NEVER use
other manufacturers’ chargers.
The optional BP-222N, BP-209N, BP-210N or BP-211N bat-
tery packs include rechargeable batteries (Ni-Cd: BP-222N,
BP-209N, Ni-MH: BP-210N, Li-Ion: BP-211N) and can be
charged approx. 300 times. Charge the battery pack before
first operating the transceiver or when the battery pack be-
comes exhausted.
If you want to charge the battery pack more than 300 times,
the following points should be observed:
• Avoid over charging. The charging period should be less than
24 hours.
• Use the battery until it becomes almost completely exhausted
under normal conditions. We recommend battery charging after
transmitting becomes impossible.
D D Battery pack life
When the operating period becomes extremely short even
after charging the battery pack fully, a new battery pack is
needed.
