DELL D600 用户手册

If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning the discs. 

 

 

1.

Hold the disc by its outer edge. You can also touch the inside edge of the center hole.  
 

 

 

 

 

2.

With a soft, dry, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line from the center to the outer edge.  
 

You can also purchase commercial products that clean discs and provide some protection from dust, fingerprints, and scratches. Cleaning products for CDs are 
safe to use on DVDs.
