Notes on discs/files

For MP3/WMA playback...
•  MP3/WMA discs require a longer readout 

time than regular CDs. (It depends on the 
complexity of the folder/file configuration.)

•  Some MP3/WMA files cannot be played back 

and will be skipped. This result from their 
recording processes and conditions.

•  When making MP3/WMA discs, use ISO 9660 

Level 1 for the disc format.

•  This unit can play back MP3/WMA files with 

the extension code <.mp3>or <.wma> 
(regardless of the letter case upper/lower).
