Playback
●
• To play MP3 files with steady sound quality, we recommend a fixed bit rate of
128 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.
