Icom IC-M87 Instruction Manual page 31

R 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.
R WARNING! Immediately wash, using clean water, any part
of the body that comes into contact with fluid from inside the
battery.
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 for the transceiver (–15˚C to +55˚C: Marine,
–25˚C to +55˚C: PMR) and the battery itself (–10˚C to +60˚C).
Using the battery out of its specified temperature range will
reduce the battery's performance and battery life. Please
note that the specified 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 tem-
perature range.
BATTERY CHARGING
CAUTION: Shorter battery life could occur if the battery is
left fully charged, completely discharged, or in an excessive
temperature environment (above +45˚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 transceiver after discharging.
You may use the battery until the remaining capacity is about
half, then keep it safely in a cool dry place with the temperature
range as below:
–20˚C to +45˚C (within a month)
–20˚C to +40˚C (within six months)
–20˚C to +35˚C (within a year)
BE SURE to replace the battery pack with a new one ap-
proximately 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 oper-
ating time of the transceiver may become short when:
• Approximately five years have passed since the battery was
manufactured.
• The battery has been repeatedly charged.
