HANDLING AND INSPECTING COMPACT DISCS

Handle a CD by its edges, see Fig 11 ; never touch the flat surfaces. Contamination from fingerprints, liquids, felt-tip pens, and labels can cause the CD to not play properly, or possibly jam in the drive.

Fig 11: Handling CD By Its Edges
When cleaning a disc, use a clean soft cloth. See Fig 12 . Wipe across the disc from the center to the outside. Do not wipe the disc in a circular motion.

Fig 12: Cleaning Disc With Clean Soft Cloth
A new CD may be rough on the inner and outer edges. The small plastic pieces causing this roughness can flake off and fall on the recording surface of the disc, causing skipping or other problems. Remove these pieces by rubbing the inner and outer edges with the side of a pencil or pen. See Fig 13 .

Fig 13: Removing Pieces By Rubbing Inner & Outer Edges
Various accessories are available to protect CDs and improve the sound quality of CDs. These accessories increase the thickness or diameter of the discs and should not be used in CD changers.
