MP3/WMA files
MP3 (MPEG Audio Layer 3) and WMA
(Windows Media Audio) are audio
compression 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 com-
patible 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 playback errors, use the appropri-
ate file extensions.
The player can play only the first ses-
sion 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.
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 emphasis function is available
only when playing MP3/WMA files re-
corded at 32, 44.1 and 48 kHz. (The
system can play MP3 files with sam-
pling frequencies of 16, 22.05, and 24
kHz. However, the emphasis function
is not available for files recorded at
these frequencies.)
The sound quality of MP3/WMA files
generally improves with higher bit rate-
s. In order to achieve a reasonable lev-
el of sound quality, discs recorded with
a bit rate of at least 128 kbps are rec-
ommended.
Playable bit rates
MP3 files:
MPEG1 LAYER3Ð64 to 320 kbps
MPEG2 LSF LAYER3Ð64 to 160 kbps
WMA files:
Ver. 7, 8 CBRÐ48 to 192 kbps
Ver. 9 CBRÐ48 to 320 kbps
The MP3/WMA player does not play
back MP3/WMA files from discs re-
corder using packet write data transfer
(UDF format). Discs should be re-
corded using pre-masteringº software
rather than packet-write software.
The m3u playlists are not compatible
with the audio player.
MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the au-
dio player.
The MP3 player is compatible with
VBR (Variable Bit Rate).
When playing back files recorded as
VBR (Variable Bit Rate) files, the play
time will not be correctly displayed if
fast-forward or reverse operations are
used.
It is not possible to check folders that
do not include MP3/WMA files.
MP3/WMA files in folders up to 8 levels
deep can be played. However, the
start of playback may be delayed when
using discs containing numerous lev-
els of folders. For this reason, we rec-
ommend creating discs with no more
than two levels of folders.
It is possible to play up to 192 folders or
255 files on one disc.

CD-R AND CD-RW DISCS
CD-R/CD-R W discs that have not
been subject to the finalizing processº
(a process that allows discs to be
played on a conventional CD player)
cannot be played.
It may not be possible to play CD-
R/CD-R W discs recorded on a music
CD recorder or a personal computer
because of disc characteristics,
scratches or dirt on the disc, or dirt,
condensation, etc. on the lens of the
unit.
It may not be possible to play discs re-
corded on a personal computer de-
pending on the application settings and
the environment. Record with the cor-
rect format. (For details, contact the
appropriate application manufacturers
of the applications.)
CD-R/CD-R W discs may be damaged
by direct exposure to sunlight, high
temperatures or other storage condi-
tions. The unit may be unable to play
some damaged discs.
If you insert a CD-RW disc into the
MP3/WMA player, playback will begin
more slowly than with a conventional
CD or CD-R disc.
Recordings on CD-R/CD-RW cannot
be played using the DDCD (Double
Density CD) system.

CARING FOR YOUR CD CHANGER,
DVD CHANGER AND DISCS
Your CD changer and DVD changer is
intended for use with 12 cm (4.7 in.)
discs only.
Extremely high temperature can keep
your CD changer and DVD changer
from working. On hot days, use air
conditioning to cool the vehicle interior
before you listen to a disc.
Bumpy roads or other vibrations may
make your CD changer and DVD chan-
ger skip.
If moisture gets into your CD changer
and DVD changer, you may not hear
any sound even though your CD
changer and DVD changer appears to
be working. Remove the discs from the
CD changer and DVD changer and
wait until it dries.
CAUTION
CD changer and DVD changer player
use an invisible laser beam which
could cause hazardous radiation
exposure if directed outside the unit.
Be sure to operate the changer
correctly.

Labeled discs
NOTICE
Do not use special shaped, trans-
parent/translucent, low quality or
labeled discs such as those shown
in the illustrations. The use of such
discs may damage the player or
changer, or it may be impossible to
eject the disc.
This system is not designed for use
of Dual Disc. Do not use Dual Disc
because it may cause damage to
the player or changer.

Correct
Wrong
Handle discs carefully, especially
when you are inserting them. Hold
them on the edge and do not bend
them. Avoid getting fingerprints on
them, particularly on the shiny side.
Dirt, scratches, warping, pin holes, or
other disc damage could cause the
changer to skip or to repeat a section of
a track. (To see a pin hole, hold the disc
up to the light.)
Remove discs from the changer when
you are not using them. Store them in
their plastic cases away from moisture,
heat, and direct sunlight.

To clean a disc: Wipe it with a soft, lint-
free cloth that has been dampened with
water. Wipe in a straight line from the cen-
ter to the edge of the disc (not in a circle).
Do not use a conventional record cleaner
or anti-static device.TERMS
Packet writeÐ
This is a general term that describes the
process of writing data on-demand to
CD-R, etc., in the same way that data is
written to floppy or hard discs.
ID3 TagÐ
This is a method of embedding track-re-
lated information in an MP3 file. This em-
bedded information can include the track
title, the artist's name, the album title, the
music genre, the year of production, com-
ments and other data. The contents can
be freely edited using software with ID3 tag
editing functions. Although the tags are re-
stricted to the number of characters, the in-
formation can be viewed when the track is
played back.
WMA TagÐ
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.
ISO 9660 formatÐ
This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are two lev-
els of regulations.
Level 1:
The file name is in 8.3 format (8 character
file names, with a 3 character file exten-
sion. File names must be composed of
one-byte capital letters and numbers. The
_º symbol may also be included.)
Level 2:
The file name can have up to 31 characters
(including the separation mark .º and file
extension). Each folder must contain few-
er than 8 hierarchies.

m3uÐ
Playlists created using WINAMPº soft-
ware have a playlist file extension (.m3u).
MP3Ð
MP3 is an audio compression standard de-
termined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
WMAÐ
WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft. It compresses files into a size
smaller than that of MP3 files. The
decoding formats for WMA files are Ver. 7,
8, and 9.
