Notes on MP3/WMAWhat is MP3/WMA?MP3 (MPEG Audio Layer-3) and WMA (Windows Media
TMAudio)
are the compression formats of digital audio. The former is
developed by MPEG (Motion Picture Experts Group), and the
latter is developed by Microsoft Corporation. Using these
compression formats, you can record the contents of about 10
music CDs on a single CD (This figure refers to data recorded on
a 650 MB CD-R or CD-RW at a fixed bit rate of 128 kbps and a
sampling frequency of 44.1 kHz).
Note:
¡MP3/WMA encoding and CD writing software programs are
not supplied with this unit.
Points to remember when making MP3/WMA filesCommon¡High bit rate and high sampling frequency are recommended
for high quality sound.
¡Selecting VBR (Variable Bit Rate) is not recommended
because playing time is not displayed properly and sound
may be skipped.
¡The playback sound quality differs depending on the encoding
circumstances. For details, refer to the instructions of your
own encoding software and writing software.MP3¡It is recommended to set the bit rate to “128 kbps or more”
and “fixed”.WMA¡It is recommended to set the bit rate to “64 kbps or more”
and “fixed”.
¡Do not set the copy protection on the WMA file to enable this
unit to play back.
Display InformationDisplayed items
Displayable characters¡Displayable length of file name/folder name: within 128 char-
acters.
¡Name files and folders in accordance with the standard of
each file system. Refer to the instructions of writing software
for details.
¡ASCII character set and special characters in each language
can be displayed.
ASCII character setA to Z, a to z, digits 0 to 9, and the following symbols:

Note:
¡With some software in which MP3/WMA format files have
been encoded, the character information may not be dis-
played properly.
¡Undisplayable characters and symbols will be converted into
an asterisk ( ). 
¡It is recommended that the length of the file name is less than

Caution
¡Never assign the “.mp3”, or “.wma” file
name extension to a file that is not in the
MP3/WMA format. This may not only pro-
duce noise from the speaker damage, but
also damage your hearing.
¡You are recommended to minimize the chances of making a
disc that contains both CD-DA files and MP3/WMA files.
¡If CD-DA files are on the same disc as MP3 or WMA files,
the songs may not play in the intended order, or some
songs may not play at all.
¡When storing MP3 data and WMA data on the same disc,
use different folders for each data.
¡Do not record files other than MP3/WMA files and unneces-
sary folder on a disc.
¡The name of an MP3/WMA file should be added by rules as
shown in the following descriptions and also comply with the
rules of each file system.
¡The file extension “.mp3” or “.wma” should be assigned to
each file depending on the file format.¡You may encounter trouble in playing MP3/WMA files or dis-
playing the information of MP3/WMA files recorded with cer-
tain writing software or CD recorders.
¡This unit does not have a play list function.
¡Although Multi-session recording is supported, the use of
Disc-at-Once is recommended.
Supported file systemsISO 9660 Level 1/Level 2, Apple Extension to ISO 9660, Joliet,

Note:
¡This unit counts the number of folders irrespective of the presence or

¡If the selected folder does not contain any MP3/WMA files, the near-
est MP3/WMA files in the order of playback will be played.
¡Playback order may be different from other MP3/WMA players even if
the same disc is used.

 Do not use irregularly shaped discs.
Notes on CD-Rs/RWs
¡You may have trouble playing back some CD-R/RW discs recorded using CD recorders (CD-R/RW drives), either due to
their recording characteristics or dirt, fingerprints, scratches, etc. on the disc surface.
¡CD-R/RW discs are less resistant to high temperatures and high humidity than ordinary music CDs.  Leaving them
inside a car for extended periods may damage and make playback impossible.
¡Some CD-R/RWs cannot be played back successfully due to incompatibility among writing software, a CD recorder (CD-
R/RW drive) and the discs.
¡This player cannot play the CD-R/RW discs if the session is not closed.
¡This player cannot play the CD-R/RW discs which contain other than CD-DA or MP3/WMA data.
¡Be sure to observe the instructions of the CD-R/RW disc for handling it.
If you use commercial CDs, they must have either of
these labels shown at right.
Some copy-protected music CDs are not playable.

FuseIf the fuse blows out, consult your dealer, or your nearest authorized Panasonic Servicenter.
Warning
¡Use fuses of the same specified rating (15 A). Using substitutes or fuses with higher ratings, or connecting the unit
directly without a fuse could cause fire or damage to the unit. If the replaced fuse fails, contact your nearest
authorized Panasonic Servicenter.MaintenanceThis unit is designed and manufactured to ensure the minimum of maintenance. Use a dry, soft cloth for routine exterior
cleaning. Never use benzine, thinner, or other solvents.
