Make sure that the disc is a digital audio disc. Your player cannot play the following discs:

• CD-ROM, CD-RW, CD-i, VCD, or DVDs
• CD-R discs that are not finalized or
• two-sided, CD/DVD discs (called DualDisc or Flip Disc)

DualDiscs or Flip Discs can cause problems when you play them, and can get stuck in your player.
