About Digital Rights Management
When using this device, obey all laws and respect local customs, privacy and legitimate rights of others, including copyrights.
Copyright protection may prevent you from copying, modifying, or transferring photos music, and other content.
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 WMDRM 10. 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 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.
Do not dismantle, cut, crush, bend, puncture, or otherwise damage the battery in any way. If a battery leaks, do not let liquid
touch skin or eyes. If this happens, immediately flush the affected areas with water, or seek medical help. Do not modify, attempt
to insert foreign objects into the battery, or immerse or expose it to water or other liquids. Batteries may explode if damaged.
Use the battery and charger for their intended purposes only. Improper use, or use of unapproved or incompatible batteries or
chargers may present a risk of fire, explosion, or other hazard, and may invalidate any approval or warranty. If you believe the
battery or charger is damaged, take it to a service center before continuing to use it. Never use a damaged battery or charger.
Only use the charger indoors. Do not charge your device during a lightning storm.
