5.1.12  Setting the Screen Saver 
 
NOTICE 
 
Burn-in effect 
The screen contents may leave a faint version (ghost) of the image in the background if 
they appear for too long.  
The "ghost" will disappear automatically after some time. The longer the same content is 
displayed on the screen, the longer it will take for the burn-in effect to disappear. 
The screen saver helps to prevent burn-in. 
Always use the screen saver.
