■ Digital rights 
management 
Digital rights management (DRM) is 
copyright protection, designed to 
prevent modification and to limit 
distribution of protected files. When 
you download protected files, such 
as sound, video, themes, or ringing 
tones to your phone, the files are 
free, but locked. You pay for the key 
to activate the file, and the 
activation key is automatically sent 
to your phone when you download 
the file. 
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.
This phone supports OMA DRM 1.0.
