Nokia 808 - Manual (Page 128)

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 license that defines your rights to use the
content.
If your device has OMA DRM-protected content, to back up both the licenses and the content, use the backup feature of
Nokia PC Suite.
Other transfer methods may not transfer the licenses 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
licenses if the files on your device become corrupted.
If your device has WMDRM-protected content, both the licenses and the content are lost if the device memory is formatted.
You may also lose the licenses and the content if the files on your device become corrupted. Losing the licenses or the
content may limit your ability to use the same content on your device again. For more info, contact your service provider.
Some licenses 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 info
Your device is intended for use with a BV-4D 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-50 . The exact Nokia charger
model number may vary depending on the plug type, identified by E, X, AR, U, A, C, K, B, or N.
In addition, third-party chargers that comply with the IEC/EN 62684 standard, and that can connect to your device micro
USB connector, may be compatible.
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.
Battery safety
Always switch the device off and unplug 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 garbage.
Do not dismantle, cut, open, crush, bend, puncture, or shred cells or batteries. If a battery leaks, do not let battery liquid
touch skin or eyes. If this happens, immediately flush the affected areas with water, or seek medical help.
Do not modify, remanufacture, attempt to insert foreign objects into the battery, or immerse or expose it to water or other
liquids. Batteries may explode if damaged.
