About 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.
Notes on discs
You can play MP3 audio tracks recorded on
CD-ROMs, CD-Rs (recordable CDs), and
CD-RWs (rewritable CDs).
The disc must be in the ISO 9660* level 1 or
level 2 format, or Joliet in the expansion
format.
* ISO 9660 Format
The most common international standard for the
logical format of files and folders on a CD-ROM.
There are several specification levels. In Level 1,
file names must be in the 8.3 format (no more than
eight characters in the name, no more than three
characters in the extension “.MP3”) and in capital
letters. Folder names can be no longer than eight
characters. There can be no more than eight nested
folder levels. Level 2 specifications allow file
names and folder names up to 31 characters long.
Each folder can have up to 8 trees.
For Joliet in the expansion format (file and folder
names can have up to 64 characters), make sure of
the contents of the writing software, etc.

Notes
• Only the letters in the alphabet and numbers can be
used for album or track names. Anything else is
displayed as “ ” (space).
• 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
MP3, the unit cannot recognize the file properly and
will generate random noise that could damage your
speakers.
• The following discs take a longer time to start
playback.
– a disc recorded with complicated tree structure.
• Depending on the encoding/writing software,
recording device, or the recording media used at the
time an MP3 file is recorded, you may encounter
such problems as disabled playback, sound
interruptions, and noise.
