Disc Accessories
There are various accessories available on the market for
protecting the disc surface and improving sound quality.
However, most of them will influence the thickness
and/or diameter of the disc. Using such accessories can
cause the disc to be out of standard specifications and
may create operational problems. We recommend not
using these accessories on discs played in Alpine CD
players.
On handling Compact Discs (CD/CD-R/CD-RW)
• Do not touch the surface.
• Do not expose the disc to direct sunlight.
• Do not affix stickers or labels.
• Clean the disc when it is dusty.
• Make sure that there are no bumps around the disc.
• Do not use commercially available disc accessories.
Do not leave the disc in the car or the unit for a long
time. Never expose the disc to direct sunlight. Heat and
humidity may damage the CD and you may not be able
to play it again.
To customers using CD-R/CD-RW
• If a CD-R/CD-RW cannot be played back, make sure
the last recording session was closed (finalized).
• Finalize the CD-R/CD-RW if necessary, and attempt
playback again.
