NOTES FOR SAVING FILES ON
THE MEDIA
When the disc is inserted, the player reads
all the files on that disc. If there are many
folders or non-MP3 files on the disc, it may
take a long time for play to begin or for the
next MP3 file to start play.
Do not save unnecessary folders or files
other than MP3 ones in the disc to be used
for MP3 listening.
We recommend that you do not save other
types files or unnecessary folders on a disc
that has MP3 files.
About “MP3”
What is the MP3?
MP3 (MPEG 1 Audio Layer-3) is a standard
technology and format for compressing a
sound sequence. The file is compressed to
about 1/10 of its original size. Sounds
outside the range of human hearing are
compressed while the sounds we can hear
are not compressed.

You can only play MP3 files recorded by
following requirements.
USABLE MEDIA
CD-Rs and CD-RWs
USABLE DISC FORMAT
You can use ISO 9660 Level 1, Level 2 and
Joliet extension format discs. In some cases,
MP3 files that are recorded in a format other
than these formats may not play normally or
the file and folder names may not be
displayed correctly.
The major specifications of the usable disc
format are as follows:
• Maximum directory steps: 8
• Usable characters for a file/folder name:
A - Z, a - z, 0 - 9, _ (underscore)
• Maximum number of characters for a file
name: 64 including quotation marks and a
3-character extension code
Notes
• When naming, be sure to add the file extension
“mp3” to the file name.
• If you put the extension “mp3” to a file other
than an MP3 file, the player cannot recognize
the file properly and will generate random noise
that could damage your speakers.
• The file name does not correspond to the ID tag.
