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 WM DRM 10 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 licence that defines your rights to use the
content.
If your device has OMA DRM-protected content, to back up both the licences and the content, use the backup feature of
Nokia Ovi Suite.
Other transfer methods may not transfer the licences which need to be restored with the content for you to be able to
continue the use of OMA DRM-protected content after the device memory is formatted. You may also need to restore the
licences if the files on your device become corrupted.
If your device has WMDRM-protected content, both the licences and the content are lost if the device memory is formatted.
You may also lose the licences and the content if the files on your device become corrupted. Losing the licences or the
content may limit your ability to use the same content on your device again. For more information, contact your service
provider.
Some licences 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.
Batteries and chargers
Battery and charger information
Your device is intended for use with a BL-5K rechargeable battery. Nokia may make additional battery models available for
this device. Always use original Nokia batteries.
This device is intended for use when supplied with power from the following chargers: AC-15. The exact Nokia charger model
number may vary depending on the plug type, identified by E, X, AR, U, A, C, K, or B.
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.
Important: Talk and standby times are estimates only. Actual times are affected by, for example, network conditions,
device settings, features being used, battery condition, and temperature.
Battery safety
Always switch the device off and disconnect the charger before removing the battery. When you unplug a charger or an
accessory, hold and pull the plug, not the cord.
When your charger is not in use, unplug it from the electrical plug and the device. Do not leave a fully charged battery
connected to a charger, as overcharging may shorten the battery's lifetime. If left unused, a fully charged battery will lose
its charge over time.
Always 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.
Accidental short-circuiting can happen when a metallic object touches the metal strips on the battery, for example, if you
carry a spare battery in your pocket. Short-circuiting may damage the battery or the connecting object.
Do not dispose of batteries in a fire as they may explode. Dispose of batteries according to local regulations. Recycle when
possible. Do not dispose as household waste.
