Digital rights management

Content owners may use different types of digital rights management (DRM)
technologies to protect their intellectual property, including copyrights. This
phone uses various types of DRM software to access DRM-protected content.
With this phone you can access content protected with OMA DRM 1.0 and 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 phone. 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.

To view the permissions for a protected file, scroll to the file, and select
Options > Activation keys. For example, you can see how many times you
can view a video or how many days you have left for listening to a song.

To extend the permissions for a file, select Options and the corresponding
option for the file type, such as Activate theme. You can send certain types
of protected files to your friends, and they can buy their own activation keys.

Copyright protections may prevent some images, music (including ringing
tones), and other content from being copied, modified, transferred or forwarded.

If your phone 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 phone memory
is formatted. You may also need to restore the activation keys in case the files on your
phone get corrupted.
