Remedies/Causes
• Use a disc with MP3/WMA/AAC tracks recorded in
a format compliant with ISO 9660 Level 1, Level 2,
Romeo, or Joliet.
• Add the extension code <.mp3>, <.wma>, or
<.m4a> to the file names.
Skip to another track or change the disc. (Do not add
the extension code <.mp3>, <.wma>, or <.m4a> to
non-MP3/WMA/AAC tracks.)
Do not use too many hierarchical levels and folders.
The playback order is determined when the files are
recorded.
This sometimes occurs during playback. This is caused
by how the tracks are recorded on the disc (eg. variable
bit rate).
Insert a disc that contains MP3/WMA/AAC tracks.
Skip to the next track encoded in an appropriate format
or to the next non-copy-protected WMA track.
This unit can only display letters (capital: A – Z,
small: a – z), numbers, and a limited number of symbols
(see page 32).
• The track played back is not a playable file format
(MP3/WMA/AAC/WAV). Skip to another file.
• Do not add the extension code <.mp3>, <.wma>,
<.m4a>, or <.wav> to non-MP3/WMA/AAC/WAV
tracks.
Playback order may differs from the one played back
using other players.
• Readout time varies depending on the USB device.
• Do not use too many hierarchy, folders and empty
folders.*
• Turn off the power then on again.
• Do not pull out or connect the USB device repeatedly
while "Reading" is displayed on the display.
* Folder that is phisically empty or folder that contains
data but does not contain valid MP3/WMA/AAC/WAV
track.
