nology standard.

audio file format for Windows
®
.
! This unit may not operate correctly depend-
ing on the application used to encode
WMA files.
! Depending on the version of Windows
Media Player used to encode WMA files,
album names and other text information
may not be correctly displayed.
! There may be a slight delay when starting
playback of WMA/AAC files encoded with
image data.
! This unit allows playback of MP3/WMA/
AAC/WAV 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/WMA/AAC/WAV files are not compati-
ble with packet write data transfer.
! The maximum number of characters which
can be displayed for a file name, including
the extension (.mp3, .wma, .m4a or .wav), is
64, from the first character.
! The maximum number of characters which
can be displayed for a folder name is 64.
! In case of files recorded according to the
Romeo file system, only the first 64 charac-
ters can be displayed.
! 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.
Important
! 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.
