To maintain high quality sound
If you have drink holders near your audio

other soft drinks onto the unit and CD. Sugary
residues on the unit or CD may contaminate
the lenses inside the unit, reduce the sound
quality, or prevent sound reproduction
altogether.

The playback order of the MP3 files
The playback order of the folders and files is as
follows:
Notes
· A folder that does not include an MP3 file is
skipped.
· When you insert a disc with many trees, it takes a
longer time to start playback.
We recommend that you make only one or two
trees for each disc.
· Maximum folder number: 255
Maximum file number: 999
Tip
To specify a desired playback order, before the
folder or file name, input the order by number
(e.g., "01", "02"), then record contents onto a disc.
(The order differs depending on the writing
software.)
About MP3 files
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 files recorded on CD-ROMs,
CD-Rs (recordable CDs), and CD-RWs
(rewritable CDs).
The disc must be in the ISO 9660*1 level 1 or
level 2 format, or Joliet or Romeo in the
expansion format.
You can use a disc recorded in Multi Session*2.
*1 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 up to 31 characters long.
Each folder can have up to 8 trees.
For Joliet or Romeo in the expansion format,
make sure the contents of the writing
software, etc.
*2 Multi Session
This is a recording method that enables
adding of data using the Track-At-Once
method. Conventional CDs begin at a CD
control area called the Lead-in and end at an
area called Lead-out. A Multi Session CD is
a CD having multiple sessions, with each
segment from Lead-in to Lead-out regarded
as a single session.
Notes
· If MP3 files and Audio data are mixed in a disc,
the first identified file or data will be played
back.
· Except while formatting ISO 9660 level 1, folder
names or file names may not be displayed
correctly.
· 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.
