Your device is powered by a rechargeable battery. The battery intended for use with
this device is BL-4S. Nokia may make additional battery models available for this

the type of plug. The plug variant is identified by one of the following: E, EB, X, AR,

wear out. When the talk and standby times are noticeably shorter than normal,
replace the battery. Use only Nokia approved batteries, and recharge your battery
only with Nokia approved chargers designated for this device. Use of other

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 appears on the display or

removing the battery.
Unplug the charger from the electrical plug and the device when not in use. Do not
