MP3/WMA playback (for KD-R304)
• Disc cannot be played back. • Use a disc with MP3/WMA tracks recorded in a format compliant
with ISO 9660 Level 1, Level 2, Romeo, or Joliet.
• Add the extension code <.mp3> or <.wma> to the file names.
• Noise is generated. Skip to another track or change the disc. (Do not add the extension
code <.mp3> or <.wma> to non-MP3 or WMA tracks.)

(“READING” keeps flashing on the display).
Do not use too many hierarchical levels and folders.
• Tracks are not played back in the order you
have intended.
Playback order is determined when the files are recorded.
• The elapsed playing time is not correct. This sometimes occurs during playback. This is caused by how the
tracks are recorded on the disc.
