AUDIO SYSTEM
” 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 1,2 (Romeo Joliet)
and UDF (2.01 or lower) 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 player can play only the first session
using multi-session compatible CDs.
” 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,
artist name.
” The sound quality of MP3/WMA files gen-
erally improves with higher bit rates. In
order to achieve a reasonable level of
sound quality, files recorded with a bit rate
of at least 128 kbps are recommended.
