DANGER! NEVER

 use or leave the battery pack in 

areas with temperatures above +60°C. High temperature 

buildup in the battery pack, such as could occur near fires 

or stoves, inside a sun heated car, or in direct sunlight may 

cause the battery pack to rupture or catch fire. Excessive 

temperatures may also degrade performance or shorten life.

R

 DANGER! DO NOT

 expose the battery pack to rain, 

snow, seawater, or any other liquids. Do not charge or use 

a wet battery pack. If the battery pack gets wet, be sure to 

wipe it dry before using.

R

 

DANGER! KEEP

 the battery pack away from fire. Fire or 

heat may cause them to rupture or explode. Dispose of a 

used battery pack in accordance with local regulations.

R

 

DANGER! NEVER

 solder the battery pack terminals, 

or 

NEVER

 modify the battery pack. This may cause heat 

generation, and the battery pack may burst, emit smoke or 

catch fire.

R

 

DANGER!

 Use the battery pack only with the transceiver 

for which it is specified. Never use a battery pack with any 

other equipment, or for any purpose that is not specified in 

this instruction manual.

R

 

DANGER!

 If fluid from inside the battery pack gets in 

your eyes, blindness can result. Rinse your eyes with clean 

water, without rubbing them, and see a doctor immediately.

R

 

WARNING!

 Immediately stop using 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!

 Immediately wash, using clean water, any 

part of the body that comes into contact with fluid from 

inside the battery pack.

R

 

WARNING! NEVER

 put the battery pack in a microwave 

oven, high-pressure container, or in an induction heating 

cooker. This could cause a fire, overheating, or cause the 

battery pack to rupture.

CAUTION:

 Always use the battery pack within the specified 

temperature range, for the transceiver (–30°C to +60°C) 

and the battery pack itself (–20°C to +60°C). Using the 

battery pack out of its specified temperature range will 

reduce the performance and the life. Please note that the 

specified temperature range of the battery pack 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 

pack is left fully charged, completely discharged, or in an 

excessive temperature environment (above +50°C) 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 to +50°C (within a month)

  –20°C to +40°C (within three months)

  –20°C to +20°C (within a year)

BE SURE

 to replace the battery pack with a new one 

approximately five 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 five years have passed since the battery 

was manufactured.

• The battery has been repeatedly charged.

 •

Charging caution

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 

pack 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

fire or damage the transceiver. Always disconnect the power

adapter before a storm.

R

 

WARNING! NEVER

 charge or leave the battery pack in 

the battery charger beyond the specified time for charging. 

If the battery pack is not completely charged by the 

specified time, stop charging and remove the battery pack 

from the battery charger. Continuing to charge the battery 

pack beyond the specified time limit may cause a fire, 

overheating, or the battery pack may rupture.

R

 

WARNING! NEVER

 insert the transceiver (the battery 

pack 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:

 Charge the battery pack within the specified 

temperature range of

 

+10°C to +40°C. Otherwise, the 

charging time will be longer, but the battery pack will not 

reach a full charge. While charging, at a point after the 

temperature goes out of the specified range, the charging 

will automatically stop.
