Caution ■
•R DANGER! NEVER short the terminals (or charging termi-
nals) of the battery pack. Also, current may flow into nearby
metal objects such as a key, so be careful when placing
battery packs (or the transceiver) in bags, 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.
•R DANGER! Use and charge only specified Icom battery
packs with Icom radios or Icom charger. 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 may cause smoke, fire, or cause the battery
to burst.
Battery caution D
•R DANGER! 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.
•R DANGER! NEVER use or leave battery pack in areas
with temperatures above +60˚C (+140˚F). High tempera-
ture 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 tem-
peratures may also degrade battery performance or shorten
battery life.
•R DANGER! DO NOT expose the battery to rain, snow,
seawater, 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.
•R DANGER! NEVER incinerate a used battery pack since
internal battery gas may cause it to rupture, or may cause
an explosion.
•R
DANGER! NEVER solder the battery terminals, or
NEVER modify the battery pack. This may cause heat gen-
eration, and the battery may burst, emit smoke or catch fire.
•R DANGER! 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
instruction manual.
•R DANGER! 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.
Misuse of Lithium-Ion batteries may result in the following
hazards:smoke,re,orthebatterymayrupture.Misuse
can also cause damage to the battery or degradation of
battery performance.

•WARNING! 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.
•WARNING! Immediately wash, using clean water, any part
of the body that comes into contact with fluid from inside
the battery.
•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 (–4˚F to +140˚F). Using the
battery out of its specified temperature range will reduce the
battery’s performance and battery life.
•CAUTION: Shorter battery life could occur if the battery is
left fully charged, completely discharged, or in an exces-
sive temperature environment (above +50˚C; +122˚F) 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 dis-
charging. You may use the battery until the battery indicator
shows half-capacity, then keep it safely in a cool dry place
atthefollowingtemperaturerange:
–20˚C (–4˚F) to +50˚C (+122˚F) (within a month).
–20˚C (–4˚F) to +35˚C (+95˚F) (within three months).

Charging caution D
•R DANGER! 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
environments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.
•WARNING! DO NOT charge or leave the battery in the bat-
tery 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.
•WARNING! NEVER insert the transceiver (battery attached
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-
edtemperaturerange:0˚C to +35˚C (+32˚F to +95˚F).
Icom recommends charging the battery at +25˚C (+77˚F).
The battery may heat up or rupture if charged out of the
specified temperature range. Additionally, battery perfor-
mance or battery life may be reduced.

R WARNING! NEVER transmit for long periods of time.
When the transceiver is used for prolonged transmissions
at high power or middle power, the transceiver radiates heat
to protect itself from overheating. The transceiver’s chassis
will become hot and may cause a burn.
•Topreventthetransceiver’soverheating,thedefaultsettingofthe
time-out timer function is set to 5 minutes (p. 62). Be careful when
the time-out timer function is turned OFF or set to a long time
period, and transmission is made for long periods.
DO NOT operate the transceiver in a situation that will
obstruct heat dissipation, especially if the transceiver is
operated with an external power supply. Heat dissipation
may be affected, and it may cause a burn, warp the casing
or damage the transceiver.
NOTE:Whenthetransceiverbecomeshotfromcontinuous
transmission, etc., the transceiver’s heat protection function
gradually reduces the output power to approximately 2.5 W,
then it stops transmission after that. This is done to protect
the transceiver itself until it has cooled down.
