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 five 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 fires 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 fire 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
specified time for charging. If the battery
is not completely charged by the specified
time, stop charging and remove the battery
from the battery charger. Continuing to
charge the battery beyond the specified
time limit may cause a fire, overheating, or
the battery may rupture.
R
WARNING!
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.
CAUTION: DO NOT
charge the battery
pack outside of the specified temperature
range for BC-235:
IC-M37/IC-M37E (AUS):
15˚C ~ 40˚C (59˚F ~ 104˚F)
IC-M37E: 15˚C ~ 35˚C (59˚F ~ 95˚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 specified
range, the charging will automatically stop.
