Notes on playing MP3
Note, however, that the MP3 recording media and
formats acceptable are limited. When writing MP3,
pay attention to the following restrictions.

Acceptable media

The MP3 recording media acceptable to this unit
are CD-ROM, CD-R, and CD-RW.
When using CD-RW, do full format not quick format
to prevent malfunction.

Acceptable medium formats

The following formats are available for the media
used in this unit. The maximum number of
characters used for file and folder name including
the delimiter (".") and three-character extension are
indicated in parentheses.
• ISO 9660 Level 1 (12 characters; Up to 11
characters are displayed)
• ISO 9660 Level 2 (31 characters; Up to 11
characters are displayed)
• Joliet (64 character; Up to 11 characters are
displayed)
For a list of available characters, see the instruction
manual of the writing software and the section
Entering file and folder names below.
MP3 written in the formats other than the above
may not be successfully played and their file names
or folder names are not properly displayed.

Settings for your MP3 encoder and CD

writer

Do the following setting when compressing audio
data in MP3 data with the MP3 encoder.
• Transfer bit rate:
MP3: 8 —320 kbps
• Sampling frequency
MP3: 16, 22.05, 24, 32, 44.1, 48 kHz
When you use your CD writer to record MP3 up
to the maximum disc capacity, disable additional
writing. For recording on an empty disc up to the
maximum capacity at once, check Disc at Once.

Entering file and folder names

When entering file and folder names, use the
alphanumeric characters described above only.
If you use any other character for entry, the file and
folder names are not displayed correctly. They may
neither be displayed correctly depending on the CD
writer used.
The unit recognizes and plays only those MP3
which have the MP3 extension (.MP3).
• A file with a name entered with characters not on the
code list may not play correctly.

Writing files into a medium

When a medium containing MP3 data is loaded,
the unit checks all the data on the medium. If the
medium contains a lot of folders or non-MP3 files,
therefore, it takes a long time until the unit starts
playing MP3.
In addition, it may take time for the unit to move to
the next MP3 file or a File Search or Folder Search
may not be performed smoothly.
Loading such a medium may produce loud noise to
damage the speakers.
• Do no attempt to play a medium containing a non-MP3
file with the MP3 extension.
The unit mistakes non-MP3 files for MP3/WMA data as
long as they have the MP3 extension.
• Do not attempt to play a medium containing non MP3.
