■MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size by using MP3
compression.
WMA (Windows Media
TMAudio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards and to the media/formats
recorded by them that can be used.

●Compatible media
Media that can be used for MP3 and WMA playback are CD-Rs and CD-RWs.
Playback in some instances may not be po ssible, depending on the status of the
CD-R or CD-RW. Playback may not be po ssible or the audio may jump if the disc
is scratched or marked with fingerprints.
●Compatible disc formats
The following disc formats can be used.
• Disc formats: CD-ROM Mode 1 and Mode 2
CD-ROM XA Mode 2, Form 1 and Form 2
• File formats: ISO9660 level 1, level 2, (Romeo, Joliet)
MP3 and WMA files written in any format other than those listed above may
not play correctly, and their file names and folder names may not be dis-
played correctly.
Items related to standards and limitations are as follows:
• Maximum directory hierarchy: 8 levels
• Maximum length of folder names/file names: 32 characters
• Maximum number of folders: 192 (including the root)
• Maximum number of files per disc: 255
●File names
The only files that can be recognized as MP3/WMA and played are those with
the extension .mp3 or .wma.
●Multi-sessions
As the audio system is compatible with multi-sessions, it is possible to play discs
that contain MP3 and WMA files. However, only the first session can be played.

3-2. Using the audio system
●ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track title
and artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags. (The
number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track
title and artist name in the same way as with ID3 tags.
●MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc are first
checked. Once the file check is finished, the first MP3 or WMA file is played. To
make the file check finish more quickly, we recommend you do not write in any
files other than MP3 or WMA files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data cannot
be played.
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be mistakenly recognized and played as MP3 and WMA files. This
may result in large amounts of interference and damage to the speakers.
●Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate
of 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be po ssible in some instances, depend-
ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depend ing on the status of the encoding
and the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take
more time to recognize the disc and in some cases, playback may not be
possible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks of
Microsoft Corporation in th e U.S. and other countries.

■CD-R and CD-RW discs
●CD-R/CD-RW discs that have not been subject to the “finalizing process” (a
process that allows discs to be played on a conventional CD player) cannot be
played.
●It may not be possible to play CD-R /CD-RW discs recorded on a music CD
recorder or a personal computer because of disc characteristics, scratches or
dirt on the disc, or dirt, condensati on, etc. on the lens of the unit.
●It may not be possible to play discs recorded on a personal computer depend-
ing on the application settings and the environment. Record with the correct
format. (For details, contact the appropriate application manufacturers of the
applications.)
●CD-R/CD-RW discs may be damaged by direct exposure to sunlight, high
temperatures or other storage conditions . The unit may be unable to play dam-
aged discs.
●If you insert a CD-RW disc into the MP3/WMA player, playback will begin
more slowly than with a conventional CD or CD-R disc.
●Recordings on CD-R/CD-RW cannot be played using the DDCD (Double
