CAUTION: DO NOT leave the 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:
–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 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.
■ 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, stop
charging and remove the battery from the battery charger.
Continuing to charge the battery beyond the specied time
limit may cause a re, overheating, or the battery may
rupture.
R 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
specied temperature range: BC-227 (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 specied
range, the charging will automatically stop.
