MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size by using MP3
compression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards that can be used and to the
media/formats on which the files are recorded. ●

MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc are first
checked. Once the file check is finished, the first MP3 or WMA file is played. To
make the file check finish more quickly, we recommend you do not write in any
files other than MP3 or WMA files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data cannot
be played.●
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be mistakenly recognized and played as MP3 and WMA files. This
may result in large amounts of interference and damage to the speakers.●
Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate
of at least 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be po ssible 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 depend ing 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
possible at all.

MP3 and WMA playback
• When a device containing MP3 or WMA files is connected, all files in the
USB memory device are checked. Once the file check is finished, the first
MP3 or WMA file is played. To make th e file check finish more quickly, we
recommend that you do not include any files other than MP3 or WMA files
or create any unnecessary folders.
• When the USB device is connected and the audio source is changed to
USB memory mode, the USB device will start playing the first file in the first
folder. If the same device is removed and reinserted (and the contents have
not been changed), the USB device will resume play from the same point in
which it was last used.●
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be skipped (not played).●
