●Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate of128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances, depend- ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depending on the status of the encoding and
the file format, poor sound quality or noise at the start of playback may result.
In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take more time to recognize the disc and in some cases, playback may not be pos-
sible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks of Microsoft Corporation in the U.S. and other countries.
■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 recorded on a personal computer depend-
ing on the application settings and the environment. Record with the correct
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 conditions. The unit may be unable to play dam-
aged 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.
CAUTION
■DVD video precaution
Conversational speech on some DVDs is recorded at a low volume to emphasize
the impact of sound effects. If you adjust the volume assuming that the conversa-
tions represent the maximum volume level that the DVD will play, you may be star-
tled by louder sound effects or when you change to a different audio source.
Loud sounds may have a significant impact on the human body or pose a driving
hazard. Keep this in mind when you adjust the volume.
