PROBLEM
Cannot play an MP3 file.
Noise or no sound generated
when an MP3 file is played.
Takes time before the unit
starts playing MP3 files.
Fails to play MP3 files in the
intended order.
The sound skips when an MP3
file is being played.
POSSIBLE CAUSE
Not conforming to ISO 9660 Level 1/2.
The MP3 file has no or invalid file name extension.
The media is scratched or dirty.
The file has the MP3 file name extension while it is not
an MP3 file.
The medium contains many folders, files, and hierarchical
levels.
The MP3 files were not written by the CD writer in the
order in which you wanted them to be played.
The media is scratched or dirty.
Use a medium conforming to ISO 9660 Level 1/2.
Add the ".MP3" extension to the MP3 file name.
Clean the media, referring to the section on "Cleaning
CDs" (see p.6).
Do not use the ".MP3" extension in non-MP3 files.
The unit checks all files on the loaded medium first. If
the medium has many files recorded, it may take a long
time for the unit before it starts playing MP3 files.
Depending on the CD writer, you may be able to set the
order in which MP3 files are to be played by writing
them onto a medium with their file names beginning
with play sequence numbers such as "01" to "99".
Clean the media, referring to the section on "Cleaning
CDs" (see p.6).
