Playing Back a Disc/USB Mass Storage Class Device
(see page 4)
• This System cannot play “packet write” discs.
• For MP3/WMA playback...
– In this manual, “file” and “track” are interchangeably used
for MP3/WMA operations.
– This System can show the Tag data (Version 1).
– MP3/WMA discs are required a longer readout time than
regular CDs. (It depends on the complexity of the group/
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 or
Level 2 for the disc format.
– This System 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/WMA file at a
sampling rate of 44.1 kHz and at bit rate of 128 kbps. This
System cannot play back files made at bit rate of less than
64 kbps.
– Playback order of MP3/WMA tracks may be different from
the one you have intended while recording. If a folder
does not include MP3/WMA tracks, they are ignored.
• Do not use the following USB devices...
– Whose rating is other than 5 V and exceeds 500 mA.
– Equipped with special functions such as data security
functions.
– Divided by 2 or more partitions.
• For the USB mass storage class device playback...
– When connecting a USB mass storage class device, also
refer to its manual.
– Connect one USB mass storage class device to the System
at a time. Do not use a USB hub.
– This System is compatible with USB 2.0 Full Speed.
– You can play back MP3/WMA files in a USB mass storage
class device (maximum data transfer rate: 2 Mbps).
– You cannot play back a file larger than 2 Gigabyte.
– This System may not play back some USB mass storage
class devices and does not support DRM (Digital Rights
Management).
• This System can recognize up to 99 groups in a disc. The
total number of groups and tracks (in a disc) that can be
recognized by the System is 512 (for MP3/WMA).
• This System can recognize up to 99 groups and 9 999 tracks
(with a maximum number of 255 tracks in a group) in a USB
mass storage class device.
If you are having a problem with your System, check this list
for a possible solution before calling for service.

system).” It cannot be played. Check the files you want to
play back.
\ The USB mass storage class device is not connected
properly.
MP3/WMA groups and tracks are not played back as you
expect.
\ Playing order is determined when the groups and tracks

The disc/USB mass storage class device sound is
discontinuous.
\ The disc is scratched or dirty.
\ MP3/WMA files have not been properly copied into the
USB mass storage class device.
Sounds from USB mass storage class device are
interrupted.
\ Noise and static electricity may stop the sound. In this
