Dell XPS 710 - Manual (Page 13)

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, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line from the center to the outer edge of the disc.
For stubborn dirt, try using water or a diluted solution of water and mild soap. 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.

all labels carry
an FCC Class B rating as distinguished by either an FCC ID number or the FCC logo, ( ), your system is considered to be a Class B digital device.
