Cautions
Media that can be played back with this
equipment
Usable media apart from audio CDs (CD-DA)
Usable media: CD-ROM, CD-R, CD-RW
Usable formats: ISO9660 level 1 and level 2
Files that can be played back: MP3 and WMA files
Creating media for playing back on this
equipment
Compressing MP3 and WMA files
Please set up the transfer bit rate setting for the compression
software when compressing MP3 and WMA files as follows:
MP3 Files: 128kbps recommended (32kbps-320kbps)
WMA Files: 128kbps recommended (64kbps-160kbps)
¶ This unit is compatible with 32kHz, 44.1kHz (recommended)
and 48kHz sampling frequencies.
Categorizing folders
As MP3 and WMA files are compressed into high-quality sound
files at an extremely high rate of compression, it is possible to
record several times more tracks than audio CDs onto a single
medium. It is therefore convenient to split the tracks into different folders by genre, artist or album for retrieval and repeat playback purposes.
¶ A maximum of 23 folders or a maximum of 200 files can be
stored on a single media.
¶ There are cases where it is not possible to save folders in the
desired sequence depending on the software being used.
Naming files
Single-byte characters between A and Z, single-byte numerals
between 0 and 9, and the single-byte underscore (_) can be
used when naming files. A maximum of twelve characters can
be displayed. Ensure that the ".MP3" (MP3 files) or ".WMA"
(WMA files) extension logs are attached to all file names.
¶ Never add the MP3 or WMA extension logs to any files other
than MP3 and WMA files. If the MP3 or WMA extension logs
are added to any files other than MP3 and WMA files, the
equipment will assume that they can be played back, and this
will produce loud noises in the headphones, resulting in damage of adverse effects.

Car cassette adapter (CAC-3A)
(W01-0989-05)
Hint for when naming folders and files
When media containing MP3 and WMA files are played back on
this equipment, the sequence in which each track is played back
will be the same as the sequence in which they were saved. It is
possible to set up the playback sequence by adding numbers
from between 01 and 99 to the front of the folder and the file
name when saving the file.
¶ There are cases where it is not possible to save files in the
desired sequence depending on the software being used.
Additional information
Depending on the MP3 and WMA compression software in use,
it is possible to save track titles, artist names and other information together with each sound file as additional information.
Although it is possible to display pre-recorded title and artist
information with this information, it is necessary to ensure that
this information has been entered in single-byte alphanumericals
(Up to a maximum of 30 alphanumericals for each.).
¶ The method of entering title and artist information will differ in
accordance with the compression software. Refer to the compression software's instruction manual or help file.
Confirming media and files
Check to ascertain that MP3 and WMA files can be played back
correctly on the personal computer in use prior to saving them
onto the media. Check to ensure that the saved file can be
played back normally.
¶ It is not possible to confirm that files can be played back cor-
rectly while they are being saved onto the media.
When saving files onto media
Ensure that the session is closed or finalized when data has
been written on media. There are cases where media on which
the session has not be closed or finalized will not be played
back correctly with this equipment.
¶ There are cases were the folder names and file names will not
be displayed correctly depending on the software used to
save them.
¶ Do not store files or folders other than MP3 and WMA on
media to be played back with this equipment.
¶ It is recommended that ten or less sessions are stored when
recording MP3 and WMA files onto a medium.
¶ There are cases where playback is not possible when MP3
and WMA files (CD-ROM) and music CD information (CD-DA)
are saved on the same media.
