Digital rights management (DRM) protected content comes with an associated license that defines
your rights to use the content.
With this device you can access content protected with PlayReady. 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.
If your device has content protected with either PlayReady or WMDRM, 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.
Battery and charger info

Charge your device with AC-20U charger. Charger plug type may vary.
Third-party chargers that comply with the IEC/EN 62684 standard, and that can connect to your
device micro USB connector, may be compatible.
Microsoft Mobile may make additional battery or charger models available for this device.
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.
Only replace the battery with a battery that is compliant with the IEEE-std-1725 standard.
Only use the battery with a charging system that has been qualified with the system per CTIA

Battery and charger safety
Always switch the device off and unplug the charger before removing the battery. To unplug a
charger or an accessory, hold and pull the plug, not the cord.
When your charger is not in use, unplug it. If left unused, a fully charged battery will lose its charge
over time.
Always keep the battery between 59°F and 77°F (15°C and 25°C) for optimal performance.
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. This may damage the battery or the other object.
Do not dispose of batteries in a fire as they may explode. Obey local regulations. Recycle when
possible. Do not dispose as household garbage.
