How to operate the MP3 player
Media capable of playing MP3 includes CD-ROM and CD-R discs.
Compared to CD-ROM media commonly used for music discs, CD-R discs
are fragile in high temperature/high humidity environments and one section
of the CD-R may become incapable of playback. Fingerprints or scratches
on the disc may prevent playback or cause skipping during playback.
Sections of a CD-R may deteriorate if left inside a vehicle for long periods of
time. It is also recommended that CD-R discs be kept in a light-blocking
case because the discs are vulnerable to ultra-violet light.
