Check
Did you insert the battery with the correct
polarity?
Are the batteries drained?
Is the AC adaptor connected correctly?
Is the door open?
Is the disc inserted correctly?
Is the disc damaged or deformed?
Has the unit been locked with the HOLD switch?
Has the unit been moved from a cold place to a
hot place?
Abrupt change of temperature may cause
condensation to form on the lens. Keep
your CD Player in a warm place until the
condensation on the lens has disappeared.
Is the volume control on the unit at the minimum
setting?
Was the unit jolted or knocked?
Is there dust, fingerprints or scratches on the
disc?
Check if the unreadable files have .mp3 as their
extension on your PC.
