CD Care Tips
Even though a CD is very durable, you should handle it with care. We
recommend the following precautions.
Keep the CD in its protective case or sleeve when you are not playing
it.
Handle a CD by its edges to avoid fingerprints, which can prevent the CD
changer's laser beams from accurately reading the CD. Your local
RadioShack store sells a suitable CD cleaner kit.
Do not write on either side of the CD, particularly the non-label side.

RadioShack store sells a Scratch and Fix kit that might help remove the
scratch and stop the skip.
