BATTERY CHARGING
■Battery caution
Misuse of Li-ion batteries may result in
the following hazards: smoke, re, or
the battery may rupture. Misuse can
also cause damage to the battery or
degradation of battery performance.
RDANGER! NEVER incinerate used
battery packs. Internal battery gas may
cause an explosion.
RDANGER! NEVER strike or otherwise
impact the battery pack. Do not use
the battery pack if it has been severely
impacted or dropped, or if the pack has
been subjected to heavy pressure. Battery
pack 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 re.
RDANGER! NEVER leave the battery
pack in places with temperatures above
60°C (140°F). High temperature buildup
in the battery cells, such as could occur
near res or stoves, inside a sun-heated
vehicle, or in direct sunlight for long
periods of time may cause the battery
cells to rupture or catch re. Excessive
temperatures may also degrade the battery
pack’s performance or shorten the battery
cell’s life.
RDANGER! NEVER place battery packs
near a re. Fire or heat may cause them
to rupture or explode. Dispose of used
battery packs in accordance with local
regulations.
RDANGER! NEVER solder the battery
terminals, or NEVER modify the battery
pack. This may cause heat generation, and
the battery may burst, emit smoke or catch
re.
RDANGER! NEVER let uid from inside
the battery get in your eyes. This can
cause blindness. Rinse your eyes with
clean water, without rubbing them, and
immediately go to a doctor.
RWARNING! NEVER let uid from inside
the battery cells come in contact with your
body. If it does, immediately wash with
clean water.
RWARNING! NEVER put the battery
pack in a microwave oven, high-
pressure container, or in an induction
heating cooker. This could cause a re,
overheating, or cause the battery cells to
rupture.
RWARNING! NEVER use deteriorated
battery packs. They could cause a re.
CAUTION: DO NOT use the battery pack
out of the specied temperature range,
–20°C ~ +60°C (–4°F ~ +140°F). Using
the battery out of its specied temperature
range will reduce its performance and
battery cell’s life.
CAUTION: DO NOT leave the battery pack
fully charged, completely discharged, or
in an excessive temperature environment
(above 50°C, 122°F) for an extended
period of time. If the battery pack must
be left unused for a long time, it must
be detached from the transceiver after
discharging. You may use the battery pack
until the remaining capacity is about half,
then keep it safely in a cool and dry place
at the following temperature range:
• Within a month
–20°C ~ +50°C (–4°F ~ +122°F)
• Within three months
–20°C ~ +40°C (–4°F ~ +104°F)
• Within a year
–20°C ~ +20°C (–4°F ~ +68°F)
CAUTION: DO NOT expose the battery
pack to rain, snow, saltwater, or any other
liquids. Do not charge or use a wet pack. If
the pack gets wet, be sure to wipe it with a
clean dry cloth before using.
CAUTION: DO NOT continue to use the
battery pack 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.

4BATTERY CHARGING
■Charging caution
RDANGER! NEVER charge the battery
pack in areas with extremely high
temperatures, such as near res 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.
RWARNING! NEVER charge the
transceiver during a lightning storm. It may
result in an electric shock, cause a re or
damage the transceiver. Always disconnect
the power adapter before a storm.
RWARNING! NEVER charge or leave the
battery in the battery charger beyond the
specied time for charging. If the battery
is not completely charged by the specied
time, stop charging and remove the battery
from the battery charger. Continuing to
charge the battery beyond the specied
time limit may cause a re, overheating, or
the battery may rupture.
RWARNING! Occasionally observe the
battery pack condition while charging. If
any abnormal condition occurs, discontinue
using the battery pack.
CAUTION: DO NOT 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.
NOTE: DO NOT charge the battery pack
outside of the specied temperature range:
15˚C ~ 40˚C (59˚F ~ 104˚F).
Otherwise, the charging time will be
longer, but the battery will not reach a full
charge. While charging, at a point after
the temperature goes out of the specied
range, the charging will automatically stop.
CAUTION: DO NOT use the power
adapter unless the power outlet is easily
accessible and near the unit. Remove it
from the power outlet when not in use.
BE SURE to replace the battery pack
with a new one approximately ve years
after manufacturing, even if it still holds
a charge. The material inside the battery
cells will become weak after a period of
time, even with little use. The estimated
number of times you can charge the pack
is between 300 and 500. Even when the
pack appears to be fully charged, the
operating time of the transceiver may
become short when:
• Approximately 5 years have passed since
the pack was manufactured.
• The pack has been repeatedly charged.
