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:
MP3/WMA files
MP3: 128kbps
WMA: 96kbps
Sampling frequency
MP3/WMA files: 44.1 kHz
• Playback order of MP3/WMA files may be
different from the one you have intended
while recording. If a folder does not include
MP3/WMA files, they are ignored.
