BATTERY CHARGING

■ Caution
(for the BP-264 Ni-MH battery)
R DANGER! NEVER short the terminals (or charging termi-
nals) of the battery pack. Also, current may flow into nearby
metal objects such as a necklace, so be careful when plac-
ing battery packs (or the transceiver) in handbags, etc.
Simply carrying with or placing near metal objects such as
a necklace, etc. may cause shorting. This may damage not
only the battery pack, but also the transceiver.
R DANGER! NEVER incinerate used battery packs. Internal
battery gas may cause an explosion.
R DANGER! NEVER immerse the battery pack in water.
If the battery pack becomes wet, be sure to wipe it dry BE-
FORE attaching it to the transceiver.
CAUTION: Always use the battery within the specified tem-
perature range, –5˚C to +60˚C (+23˚F to +140˚F). Using the
battery out of its specified temperature range will reduce the
battery's performance and battery life.
CAUTION: Shorter battery life could occur if the battery is
left completely discharged, or in an excessive temperature
environment (above +55˚C; +131˚F) for an extended period
of time. If the battery must be left unused for a long time,
it must be detached from the radio after charging. Keep it
safely in a cool dry place at the following temperature range:
–20˚C to +45˚C (–4˚F to +113˚F) (up to a month)
–20˚C to +35˚C (–4˚F to +95˚F) (up to six months)
–20˚C to +25˚C (–4˚F to +77˚F) (up to a year*)
* We recommend charging the battery pack every 6 months.

Clean the battery terminals to avoid rust or misscontact.
Keep the battery terminals clean. It's a good idea to clean
the battery terminals once a week.
If your Ni-MH battery pack seems to have no capacity, even
after being charged, completely discharge it by leaving the
power ON overnight. Then, fully charge the battery pack again.
If the battery pack still does not retain a charge (or only very lit-
tle charge), a new battery pack must be purchased. (p. 53)
Prior to using the transceiver for the first time, the battery
pack must be fully charged, for optimum life and operation.
• Recommended temperature range for charging:
between +10°C (+50˚F) and +35°C (+95˚F) (rapid charge:
with BC-191, BC-197) or between 0°C (+32˚F) and +45°C
(+113˚F) (regular charge: with BC-192)
• Use only the supplied charger or optional charger (BC-191,
BC-197 for rapid charging, BC-192 for regular charging).
NEVER use other manufacturers' chargers.
The battery pack contains a rechargeable battery.
Charge the battery pack before first operating the trans-
ceiver, or when the battery pack becomes exhausted.
If you want to prolong the battery life, the following points
should be observed:
• DO NOT overcharge the battery pack. The charging time
period should be less than 48 hours.
• Use the battery pack until it becomes almost completely
exhausted, under normal conditions. We recommend bat-
tery charging after transmitting becomes impossible.
