Battery and charger information

This device has an internal,
nonremovable, rechargeable battery. Do
not attempt to remove the battery from
the device as you may damage the
device. This device is intended for use
when supplied with power from the
following chargers: AC-6 and DC-6. The
exact charger model number may vary
depending on the type of plug. The plug
variant is identified by one of the
following: E, EB, X, AR, U, A,C, K, or UB.
The battery can be charged and
discharged hundreds of times, but it will
eventually wear out. Recharge your
battery only with Nokia approved
chargers designated for this device.

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
