Digital rights management
Content owners may use different types of digital rights
management (DRM) technologies to protect their intellectual
property, including copyrights. This device uses various types
of DRM software to access DRM-protected content. With this
device you can access content protected with WMDRM 10,
OMA DRM 1.0, OMA DRM 1.0 forward lock, and OMA DRM 2.0. If
certain DRM software fails to protect the content, content
owners may 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 activation key that defines your rights to
use the content.
If your device has OMA DRM-protected content, to back up
both the activation keys and the content, use the backup
feature of Nokia PC Suite. If your device has OMA DRM-
protected content, to back up both the activation keys and
the content, use the backup feature of Nokia Ovi Suite.
If your device has WMDRM-protected content, both the
activation keys and the content will be lost if the device
memory is formatted. You may also lose the activation keys
and the content if the files on your device get corrupted.
Losing the activation keys or the content may limit your
ability to use the same content on your device again. For more
information, contact your service provider.
Some activation keys 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.

Accessories
Warning:
Use only batteries, chargers, and accessories approved by
Nokia for use with this particular model. The use of any other

Battery
Battery and charger information
Your device is powered by a rechargeable battery. The battery
intended for use with this device is BL-5CT. 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-8/AC-15. 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, or UB.
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. Use of an unapproved battery or 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 appears on the display or before any calls can be
made.
Always switch the device off and disconnect the charger
before removing the battery.
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
