BATTERY CHARGING
BASIC MANUAL
■
Charging cautions
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 AC 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.
NOTE: DO NOT
charge the battery pack
outside of the specified temperature range:
15°C ~ 40°C. 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.

Battery cautions
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.
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.
