MP3/WMA FILES

 MP3 (MPEG Audio Layer 3) and WMA
(Windows Media Audio) are audio com-
pression standards.
 The MP3/WMA player can play MP3 and
WMA files on CD-ROM, CD-R and CD-
RW discs.
 The unit can play disc recordings compati-
ble with ISO 9660 level 1 and level 2 and
with the Romeo and Joliet file system.
 When naming an MP3 or WMA file, add
the appropriate file extension (.mp3 or
.wma).
 The MP3/WMA player plays back files
with .mp3 or .wma file extensions as MP3
or WMA files. To prevent noise and play-
back errors, use the appropriate file exten-
sions.
 The MP3/WMA player can play only the
first session when using multi-session
compatible CDs.
 MP3 player: MP3 files are compatible with
the ID3 Tag Ver. 1.0, Ver. 1.1, Ver. 2.2 and
Ver. 2.3 formats. The unit cannot display
disc title, track title and artist name in
other formats.
 USB memory: MP3 files are compatible
with the ID3 Tag Ver. 1.0, Ver. 1.1, Ver.
2.2, Ver. 2.3 and Ver. 2.4 formats. The unit
cannot display track title and artist name
in other formats.
 WMA files can contain a WMA tag that is
used in the same way as an ID3 tag. WMA
tags carry information such as track title
and artist name.

when playing MP3/WMA files recorded at
32, 44.1 and 48 kHz.
