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 circles).
Dry it with another soft, lint−free cloth. Do
not use a conventional record cleaner or
anti−static device.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 MP3/WMA player can play only
the first session 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 can-
not display disc title, track title and art-
ist name in other formats.
USB memory—MP3 files are compat-
ible 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 emphasis function is available
only when playing MP3/WMA files re-
corded at 32, 44.1 and 48 kHz.

Sampling frequency
MP3 files for MP3 player:
MPEG 1 LAYER 3—32, 44.1, 48 kHz
MPEG 2 LSF LAYER 3—16, 22.05, 24
kHz
MP3 files for USB memory:
MPEG 1 AUDIO LAYER 2, 3—32,
44.1, 48 kHz
MPEG 2 AUDIO LAYER 2, 3—16,
22.05, 24 kHz
MPEG 2.5—8, 11.025, 12 kHz
WMA files for WMA player:
Ver. 7, 8, 9 CBR—32, 44.1, 48 kHz
WMA files for USB memory:
Ver. 9—HIGH PROFILE 32, 44.1, 48
kHz
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 for MP3 player:
MPEG1 LAYER3—64 to 320 kbps
MPEG2 LSF LAYER3—64 to 160 kbps
MP3 files for USB memory:
MPEG 1 AUDIO LAYER 2, 3—32 to
320 kbps
MPEG 2 AUDIO LAYER 2, 3—32 to
160 kbps
MPEG 2.5—32 to 160 kbps
WMA files for WMA player:
Ver. 7, 8 CBR—48 to 192 kbps
Ver. 9 CBR—48 to 320 kbps
WMA files for USB memory:
Ver. 9 —HIGH PROFILE 32 to 320
kbps, VBR (Variable Bit Rate)
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−mastering” software
rather than packet−write software.
M3u playlists are not compatible with
the audio player.
MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the au-
dio player.
The 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.

The play order of the compact disc with
the structure shown above is as fol-
lows:
001.mp3 002.wma . . . 006.mp3
MP3/WMA player—It is possible to
play up to 192 folders or 255 files on
one disc.
U S B me m o r y—It is possible to play up
to 999 folders, 255 files per folder or
65,025 files in device.
The order changes depending on the
PC and MP3/WMA encoding software
you use.CD−R and CD−RW discs
CD−R/CD−RW discs that have not
been subject to the “finalizing process”
(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−RW 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−RW 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.
