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).
• It is recommended to make the files at the
following condition:
