Nokia Lumia 2520 - 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.

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.
