112 Product and safety information
Digital rights management (DRM) protected content comes with an associated licence that defines your rights to use the content.
If your device has OMA DRM-protected content, to back up both the licences and the content, use the backup feature of Nokia
Ovi Suite.
Other transfer methods may not transfer the licences 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 licences in case
the files on your device get corrupted.
If your device has WMDRM-protected content, both the licences and the content will be lost if the device memory is formatted.
You may also lose the licences and the content if the files on your device get corrupted. Losing the licences or the content may
limit your ability to use the same content on your device again. For more information, contact your service provider.
Some licences may be connected to a specific SIM card, and the protected content can be accessed only if the SIM card is inserted
in the device.

Nokia battery authentication guidelines
Always use original Nokia batteries for your safety. To help ensure that you are getting an original Nokia battery, purchase it
from a Nokia authorised service centre or dealer, and check the hologram label.
Authenticate hologram
1 Look at the hologram. You should see the Nokia connecting hands symbol from one angle and the Nokia Original
Accessories logo from the other angle.
2 Angle the hologram left, right, down, and up. You should see 1, 2, 3 and 4 dots on each side respectively.
However, this is not a total assurance of the authenticity of the battery. If you cannot confirm authenticity or if you have any
reason to believe that your Nokia battery with the hologram on the label is not an authentic Nokia battery, stop using the
battery and take it to the nearest Nokia authorised service centre or dealer.
