How to operate the CD (MP3/WMA) player

Media
Media capable of playing MP3/WMA includes CD-R and CD-RW discs. Compared to CD-ROM
media commonly used for music discs, CD-R and CD-RW discs are fragile in high temperature/high
humidity environments and one section of the CD-R and CD-RW may become incapable of
playback. Fingerprints or scratches on the disc may prevent playback or cause skipping during
playback. Sections of a CD-R and CD-RW may deteriorate if left inside a vehicle for long periods of
time. It is also recommended that CD-R and CD-RW discs are kept in a light-blocking case because
the discs are vulnerable to ultra-violet light.
Format of discs
The format of discs to be used must be ISO9660 Level 1 or Level 2.
Control items for this standard are as follows:
• Maximum directory layers: 8 layers
• Maximum characters for folder names/file names:32 (including "." and 3 letter file extension)
•
Allowable characters for folder names/file names:
A~Z, 0~9, _ (underscore)
•
Number of files/folders possible on a single disc: 999
• Total number of folders possible on a single disc:255
• Maximum folders this main unit can recognize: 256*
*: A root directory is counted as one folder.
File names
Only files with the MP3/WMA file extension ".mp3", ".wma" can be recognized as MP3/WMA and played.
Be sure to save MP3 files with the ".mp3" file extension. Be sure to WMA files with the ".wma" file
extension. The "MP" letters of the file extension will be recognized whether entered as uppercase letters
or lowercase letters.
CAUTION
If the ".mp3", ".wma" file extension is attached to a file other than an MP3/WMA file, that file will be
mistakenly recognized by this main unit as an MP3/WMA file and played, resulting in loud noise
output that can damage the speakers. Be sure to avoid attaching the ".mp3", ".wma" file extension
to files that are not MP3/WMA files.
