will eventually wear out. Recharge
your battery only with Nokia
approved chargers designated for
this device. Use of an unapproved
charger may present a risk of fire,
explosion, leakage, or other hazard.
If a battery is being used for the first
time or if the battery has not been
used for a prolonged period, it may be
necessary to connect the charger,
then disconnect and reconnect it to
begin charging the battery. If the
battery is completely discharged, it
may take several minutes before the
charging indicator light is displayed.
Unplug the charger from the
electrical plug and the device when
not in use. Do not leave a fully
charged battery connected to a
charger, since overcharging may
shorten its lifetime. If left unused, a
fully charged battery will lose its
charge over time.
Always try to keep the battery
between 15°C and 25°C (59°F and
77°F). Extreme temperatures reduce
the capacity and lifetime of the
battery. A device with a hot or cold
battery may not work temporarily.
Battery performance is particularly
limited in temperatures well below
freezing.
Do not dispose of batteries in a fire as
they may explode. Batteries may also
explode if damaged.
Never use any charger that is
damaged.
