explosion may occur.
R WARNING!
Personal injury, re hazard or
electric shock may occur.
CAUTION Equipment damage may occur.
NOTE
Recommended for optimum use. No
risk of personal injury, re or electric
shock.
Icom is not responsible for the destruction, damage to,
or performance of any Icom or non-Icom equipment, if
the malfunction is because of:
• Force majeure, including, but not limited to, res,
earthquakes, storms, oods, lightning, other natural
disasters, disturbances, riots, war, or radioactive
contamination.
• The use of Icom transceivers with any equipment that
is not manufactured or approved by Icom.
Even when the transceiver power is OFF, a slight current
still ows in the circuits. Remove the battery pack from the
transceiver when not using it for a long time. Otherwise,
the installed battery pack will become exhausted, and will
need to be recharged or replaced.
MAKE SURE to turn OFF the transceiver power before
connecting the supplied or optional equipment.
Operate the transceiver that complies with your local laws
and regulations.
Depending on countries and/or regions, transceiver’s
output power and/or operations on specic frequencies
may be restricted to avoid interferences with existing radio
stations or services.
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.
R DANGER! 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.
R DANGER! NEVER place or leave battery packs in areas
with temperatures above 60°C (140°F). High temperature
buildup in the battery, 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
battery performance or shorten battery cell’s life.
R DANGER! 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 battery pack 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 re.
R DANGER! NEVER place or leave battery packs near
re. Fire or heat may cause them to rupture or explode.
Dispose of used battery packs in accordance with local
regulations.
R DANGER! 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.
R DANGER! NEVER expose the battery pack 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 WARNING! NEVER use deteriorated battery packs.
They could cause a re.
R WARNING! NEVER put the battery 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.
R WARNING! NEVER 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.
R WARNING! NEVER let uid from inside the battery
cells come in contact with you body. If it does, immediately
wash with clean water.
CAUTION: DO NOT use the battery pack out of the
specied temperature range, for the transceiver,
(–30°C ~ +60°C, –22°F ~ +140°F), and the battery pack
itself (–20°C ~ +60°C, –4°F ~ +140°F). Using the battery
out of its specied temperature range will reduce its
performance and battery cell’s life. Please note that the
specied temperature range of the battery may exceed
that of the transceiver. In such cases, the transceiver
may not work properly because it is out of its operating
temperature range.
CAUTION: Shorter battery life could occur if the battery
is left 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:
–20°C ~ +50°C (–4°F ~ +122°F) (within a month)
–20°C ~ +40°C (–4°F ~ +104°F) (within three months)
–20°C ~ +20°C (–4°F ~ +68°F) (within a year)
BE SURE to replace the battery pack with a new one
approximately ve years after manufacturing, even if it still
holds a charge. The inside battery material will become
weak after a period of time, even with little use. The
estimated number of times you can charge the battery is
between 300 and 500. Even when the battery appears to
be fully charged, the operating time of the transceiver may
become short when:
• Approximately ve years have passed since the battery
was manufactured.
• The battery has been repeatedly charged.
The battery cells may deteriorate and swell due to their
characteristics if used in an environment and conditions
such as: frequently charged, recharged immediately after
full charge, used or saved in a hot place, or charged
by methods other than the instructions. If the battery
pack swells, it has reached the end of its life due to
deterioration. Replace it with a brand new one.
D Charging caution
R DANGER! 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.
R WARNING! 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.
R WARNING! NEVER charge or leave the battery in the
battery charger beyond the specied time for charging. If
the battery is not completely charged by the specied time,
