! With some applications used to encode
WMA files, this unit may not operate cor-
rectly.
! With some applications used to encode
WMA files, album names and other text in-
formation may not be correctly displayed.
! This unit allows playback of MP3/WMA/
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/WAV files are not compatible
with packet write data transfer.
! The maximum number of characters which
can be displayed for a file name, including
the extension (.mp3, .wma 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 and Joliet file system, only the first
64 characters can be displayed.
! When playing discs with MP3/WMA/WAV
files and audio data (CD-DA) such as CD-
EXTRA and MIXED-MODE CDs, both types
can be played only by switching mode be-
tween MP3/WMA/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.
Important
! When naming an MP3/WMA/WAV file, add
the corresponding filename extension (.mp3,
.wma or.wav).
! This unit plays back files with the filename ex-
tension (.mp3, .wma or .wav) as an MP3/
WMA/WAV file. To prevent noise and malfunc-
tions, do not use these extensions for files
other than MP3/WMA/WAV files.
MP3 additional information
! Files are compatible with the ID3 Tag Ver.
1.0, 1.1, 2.2, 2.3 and 2.4 formats for display
of album (disc title), track (track title) and
artist (track artist).
Ver 2.x of ID3 Tag is given priority when
both Ver 1.x and Ver 2.x exist.
! The emphasis function is valid only when
MP3 files of 32, 44.1 and 48 kHz frequen-
cies are played back. (16, 22.05, 24, 32,
44.1, 48 kHz sampling frequencies can be
played back.)
! There is no m3u playlist compatibility.
! There is no compatibility with the MP3i

! The sound quality of MP3 files generally be-
comes better with an increased bit rate.
This unit can play recordings with bit rates
from 8 kbps to 320 kbps, but in order to be
able to enjoy sound of a certain quality, we
recommend using only discs recorded with
a bit rate of at least 128 kbps.
