MP3/WMA folders/tracks configuration
• 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 results 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 that you make each MP3
file at a sampling rate of 44.1 kHz and at a bit
rate of 128 kbps. Similarly each WMA file at a
sampling rate of 44.1 kHz and at a bit rate of
96 kbps.
• Playback order of MP3/ WMA files may be
different from the one you have intended
when recording. If a folder does not contain
MP3/ WMA files, it is ignored.
• This unit cannot play “packet write” discs.
• If a CD-RW has been recorded in a different
format, erase all data on the CD-RW
completely before recording on it.
• This unit can recognize up to a total of 511
tracks and folders on a disc, and 65536 files
in up to 200 groups (maximum 500 files in a
single group) on a USB device.

disc when placing it back in its case.
• Avoid exposure to direct sunlight,
temperature extremes, and moisture.
Cleaning discs
• Wipe the disc with a soft cloth in a straight
line from center to edge.
Cleaning the unit
• Stains should be wiped off with a soft cloth. If
the unit is heavily stained, wipe it with a cloth
