Battery And Charger - Nokia E52 User Manual

ask that such DRM software's ability to access new DRM-
protected content be revoked. Revocation may also
prevent renewal of such DRM-protected content already in
your device. Revocation of such DRM software does not
affect the use of content protected with other types of DRM
or the use of non-DRM-protected content.
Digital rights management (DRM) protected content
comes with an associated licence that defines your rights
to use the content.
If your device has OMA DRM-protected content, to back up
both the licence and the content, use the backup feature
of Nokia PC Suite.
If your device has WMDRM-protected content, both the
licence and the content will be lost if the device memory
is formatted. You may also lose the licence and the content
if the files on your device get corrupted. Losing the licence
or the content may limit your ability to use the same
content on your device again. For more information,
contact your service provider.
Some licence may be connected to a specific SIM card, and
the protected content can be accessed only if the SIM card
is inserted in the device.

Battery and charger

information
Your device is powered by a rechargeable battery. The
battery intended for use with this device is BP-4L. Nokia
may make additional battery models available for this
device. This device is intended for use when supplied with
power from the following chargers: AC-10. 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. For example, the
model numbers for the charger can be, among others,
AC-10 etc.
The battery can be charged and discharged hundreds of
times, but it will eventually 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.
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
before any calls can be made.
Safe removal. Always switch the device off and disconnect
the charger before removing the battery.
Proper charging. 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.
Avoid extreme temperatures. 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.
