Notes
• The file names and folder names must be ISO
9660 level 1 compliant.
• 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 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.
THE USABLE NUMBER OF
FOLDERS/FILES
• Maximum folder number: 255
• Maximum file number: 255
SETTINGS FOR COMPRESSION
SOFTWARE AND WRITING
SOFTWARE
• To compress a source for an MP3 file, we
recommend setting the transfer bit rate of
the compression software to “44.1 kHz”,
“128kbps”, and “Constant Bit Rate”.
• To record up to the maximum capacity, set
to the “halting of writing”.
• To record at one time up to the maximum
capacity on media that has nothing
recorded it, set to “Disc at Once”.
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.
