driving a vehicle. Safe driving requires your full attention—
anything less may result in an accident.
RWARNING! NEVER operate or touch the trans-
ceiver with wet hands. This may result in an electric shock or
may damage the transceiver.
DO NOT operate the transceiver near unshielded electri-
cal blasting caps or in an explosive atmosphere.
DO NOT push [PTT] unless you actually intend to transmit.
BE CAREFUL! The transceiver will become hot when
operating it continuously for long periods of time.
DO NOT use or place the transceiver in direct sun-
light or in areas with temperatures below –20°C or above
+60°C.

BATTERY CHARGING
■Caution (for the BP-264 Ni-MH battery)
RDANGER! NEVER short terminals (or charging terminals)
of the battery pack. Also, current may flow into nearby metal
objects such as a necklace, so be careful when placing bat-
tery packs (or the transceiver) in handbags, etc.
Simply carrying with or placing near metal objects such as
a necklace, etc. may cause shorting. This may damage not
only the battery pack, but also the transceiver.
RDANGER! NEVER incinerate used battery packs. Internal
battery gas may cause an explosion.
RDANGER! NEVER immerse the battery pack in water.
If the battery pack becomes wet, be sure to wipe it dry BE-
FORE attaching it to the transceiver.
CAUTION: Always use the battery within the specified tem-
perature range, –5˚C to +60˚C. Using the battery out of its
specified temperature range will reduce the battery’s perfor-
mance and battery life.
CAUTION: Shorter battery life could occur if the battery is
left completely discharged, or in an excessive temperature
environment (above +55˚C) for an extended period of time.
If the battery must be left unused for a long time, it must be
detached from the radio after charging. Keep it safely in a
cool dry place at the following temperature range:
–20˚C to +45˚C (up to a month)
–20˚C to +35˚C (up to six months)
–20˚C to +25˚C (up to a year*)
* We recommend charging the battery pack every 6 months.
Clean the battery terminals to avoid rust or misscontact.
Keep battery terminals clean. It’s a good idea to clean bat-
tery terminals once a week.
If your Ni-MH 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 lit-
tle charge), a new battery pack must be purchased. (p. 39)
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:
between +10°C and +40°C (rapid charge: with BC-191) or
between 0°C and +45°C (regular charge: with BC-192)
• Use the supplied charger or optional charger (BC-191 for
rapid charging, BC-192 for regular charging) only. NEVER
use other manufacturers’ chargers.
The battery pack contains a rechargeable battery.
Charge the battery pack before first operating the trans-
ceiver, or when the battery pack becomes exhausted.
If you want to prolong the battery life, the following points
should be observed:
• Avoid over charging. The charging time period should be
less than 48 hours.
• Use the battery pack until it becomes almost completely
exhausted, under normal conditions. We recommend bat-
tery charging after transmitting becomes impossible.

■Caution (for the BP-265 Li-Ion battery)
RDANGER! NEVER short terminals (or charging terminals)
of the battery pack. Also, current may flow into nearby metal
objects such as a necklace, so be careful when placing bat-
tery packs (or the transceiver) in handbags, etc.
Simply carrying with or placing near metal objects such as
a necklace, etc. may cause shorting. This may damage not
only the battery pack, but also the transceiver.
RDANGER! Use and charge only specified Icom battery
packs with Icom radios or Icom chargers. Only Icom battery
packs are tested and approved for use with Icom radios or
charged with Icom chargers. Using third-party or counterfeit
battery packs or chargers may cause smoke, fire, or cause
the battery to burst.
DBattery caution
RDANGER! DO NOT hammer or otherwise impact the bat-
tery. Do not use the battery if it has been severely impacted
or dropped, or if the battery has been subjected to heavy
pressure. Battery damage may not be visible on the outside
of the case. Even if the surface of the battery does not show
cracks or any other damage, the cells inside the battery may
rupture or catch fire.
RDANGER! NEVER use or leave battery pack in areas
with temperatures above +60˚C. High temperature buildup in
the battery, such as could occur near fires or stoves, inside a
sun heated car, or in direct sunlight may cause the battery to
rupture or catch fire. Excessive temperatures may also de-
grade battery performance or shorten battery life.
RDANGER! DO NOT expose the battery to rain, snow, sea-
water, or any other liquids. Do not charge or use a wet battery.
If the battery gets wet, be sure to wipe it dry before using.
RDANGER! NEVER incinerate a used battery pack since
internal battery gas may cause it to rupture, or may cause
an explosion.
RDANGER! NEVER solder the battery terminals, or
NEVER modify the battery pack. This may cause heat gener-
ation, and the battery may burst, emit smoke or catch fire.
RDANGER! Use the battery only with the transceiver for
which it is specified. Never use a battery with any other
equipment, or for any purpose that is not specified in this in-
struction manual.
RDANGER! If fluid from inside the battery gets in your
eyes, blindness can result. Rinse your eyes with clean water,
without rubbing them, and see a doctor immediately.
RWARNING! Immediately stop using the battery if it emits an
abnormal odor, heats up, or is discolored or deformed. If any of
these conditions occur, contact your Icom dealer or distributor.
R WARNING! Immediately wash, using clean water, any
part of the body that comes into contact with fluid from in-
side the battery.
3BATTERY CHARGING
Misuse of Li-Ion batteries may result in the following haz-
ards: smoke, fire, or the battery may rupture. Misuse can
also cause damage to the battery or degradation of battery
performance.

BATTERY CHARGING
R WARNING! NEVER put the battery in a microwave oven,
high-pressure container, or in an induction heating cooker.
This could cause a fire, overheating, or cause the battery to
rupture.
CAUTION: Always use the battery within the specified tem-
perature range, –20˚C to +60˚C. Using the battery out of its
specified temperature range will reduce the battery’s perfor-
mance and battery life.
CAUTION: Shorter battery life could occur if the battery is
left fully charged, completely discharged, or in an excessive
temperature environment (above +50˚C) for an extended pe-
riod of time. If the battery must be left unused for a long time,
it must be detached from the radio after discharging. You
may use the battery until the battery indicator shows half-ca-
pacity, and then keep it safely in a cool dry place at the fol-
lowing temperature range:
–20˚C to +50˚C (up to a month)
–20˚C to +35˚C (up to three months)
–20˚C to +20˚C (up to a year)
DCharging caution
RDANGER! NEVER charge the battery pack in areas with
extremely high temperatures, such as near fires or stoves,
inside a sun-heated vehicle, or in direct sunlight. In such en-
vironments, the safety/protection circuit in the battery will ac-
tivate, causing the battery to stop charging.
R WARNING! DO NOT charge or leave the battery in the
battery charger beyond the specified time for charging. If the
battery is not completely charged by the specified time, stop
charging and remove the battery from the battery charger.
Continuing to charge the battery beyond the specified time
limit may cause a fire, overheating, or the battery may rup-
ture.
R WARNING! NEVER insert the transceiver (battery at-
tached to the transceiver) into the charger if it is wet or
soiled. This could corrode the battery charger terminals or
damage the charger. The charger is not waterproof.
CAUTION: DO NOT charge the battery outside of the speci-
fied temperature range: BC-193 (+10˚C to +40˚C
). Icom rec-
ommends charging the battery at +20˚C. The battery may
heat up or rupture if charged out of the specified tempera-
ture range. Additionally, battery performance or battery life
may be reduced.
The supplied battery pack, charger, and AC adapter dif-
fer, or no supplied depending on the version.
