before using them.
MP3 files
• MP3 is short for MPEG Audio Layer 3 and
refers to an audio compression technology
standard.
• This unit allows playback of MP3 files on CD-
ROM, CD-R and CD-RW discs. Disc recordings
compatible with level 1 and level 2 of ISO9660
and with the Romeo and joliet file system can
be played back.
• It is possible to play back multi-session
compatible recorded discs.
• MP3 files are not compatible with packet write
data transfer.
• The max. number of characters which can be
displayed for a file name, including the
extension (.mp3), is 30 characters from the first
character.
• The max. number of characters which can be
displayed for a folder name is 30 characters.
• In case of files recorded according to the
Romeo and Joliet file system, only the first 30
characters can be displayed. Depending on the
width of the characters, the screen may not be
able to display 30 characters.
• When playing discs with MP3 files and audio
data (CD-DA) such as CD-EXTRA and MIXED-
MODE CDs, both types can be played only by
switching mode between MP3 and CD-DA.
• The folder selection sequence for playback and
other operations becomes the writing
sequence used by the writing software. For this
reason, the expected sequence at the time of
playback may not coincide with the actual
playback sequence. However, there also is
some writing software which permits setting of
the playback order.
• Some audio CDs contain tracks that merge
into one another without a pause. When these
discs are converted to MP3 files and burned to
a CD-R/CD-RW/CD-ROM, the files will be
played back on this player with a short pause
between each one, regardless of the length of
the pause between tracks on the original audio
CD.
