Digital rights management
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 WMDRM 10, OMA DRM 1.0, OMA DRM 1.0 forward lock, 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.
DRM-protected content comes with an associated activation key that defines your rights to
use the content.
If your device has OMA DRM-protected content, to back up both the activation keys and the
content, use the backup feature of Nokia PC Suite. Other transfer methods may not transfer
the activation keys 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 activation keys in case the files on your device get corrupted.
If your device has WMDRM-protected content, both the activation keys and the content will
be lost if the device memory is formatted. You may also lose the activation keys and the content
if the files on your device get corrupted. Losing the activation keys or the content may limit
your ability to use the same content on your device again. For more information, contact
your service provider.
