When using this device, obey all laws and respect local

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

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 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.
