! When playing discs with MP3/WMA/AAC/
WAV 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/WMA/AAC/WAV 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 per-
mits 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/WMA/
AAC/WAV 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.
! When naming an MP3/WMA/AAC/WAV file,
add the corresponding filename extension
(.mp3, .wma, .m4a or .wav).
! This unit plays back files with the filename ex-
tension (.mp3, .wma, m4a or .wav) as an MP3/
WMA/AAC/WAV file. To prevent noise and
malfunctions, do not use these extensions for
files other than MP3/WMA/AAC/WAV files.
