CD-R and CD-RW discs with mp3 format “Sound” files
In the case of discs that include mp3 files, follow not only the general recommendations for CD-R and CD-
RW discs, but also the following specific recommendations:
• The format of your mp3 files should be ISO 9660 or JOLIET. These files are compatible with DOS and
Windows applications as well as with Mac OS.
• Your mp3 files must have a name no longer than 12 characters as well as the suffix “.mp3”. They must be
recorded in the form: title.mp3. Ensure that you do not leave spaces or use special characters such as ( . ,
/ , \ , = ,+) in the name.
• Do not attempt to record protected mp3 files. Such files are coded and protected.
• Use a decompression transfer rate of at least 128 kb/sec (kilobytes/second) when recording mp3 files.
Sound quality with mp3 files basically depends on the rate of compression/ decompression you choose.
Getting audio CD quality sound requires an analog/digital sampling rate, that is conversion to mp3
format, of at least 128 kb/sec and up to 160 kb/sec.
However, choosing higher rates, like 192 kb/sec or more, only rarely give even better sound quality.
Conversely, files with sampling rates below 128 kb/sec will not be played properly.
Important: The above recommendations cannot be taken as a guarantee that the DVD player will play mp3
recordings, or as an assurance of sound quality. You should note that certain technologies and methods for
mp3 file recording on CD-Rs prevent optimal playback of these files on your DVD player (that is degraded
sound quality and even, in some cases, inability of the player to read the file or files).

Maintenance of Cabinet
For safety reasons, when cleaning the cabinet be sure to disconnect the AC power cord from the AC outlet.
• Do not use benzene, thinner, or other solvents for cleaning.
• Wipe the cabinet with a soft cloth.
Formation of Condensation
• Due to sharp changes in temperature and humidity, condensation may form if warm air comes in
contact with any cold parts inside the player.
• When condensation forms inside the player, the player may not operate correctly. If this occurs, leave the
player at room temperature until the inside of the player becomes dry and operational.
• If condensation forms on a disc, wipe the disc with a soft, dry cloth by moving the cloth from the center
hole toward the outer edge.
Handling Discs
• Don’t touch the disc’s data surfaces. Hold by the edges or by one edge and the hole in the center.
• Don’t affix labels or adhesive tape to label surfaces. Don’t scratch or damage the label.
• Do not use damaged (cracked or warped) discs.
Cleaning Discs
• Dirty discs can cause reduced video and audio performance. Always keep discs clean by wiping them
gently with a soft cloth from the inner edge toward the outer perimeter.
