Grundig Scenos UMS 4400 DVD manual Rectifying minor problems, Fault, Possible cause/remedy

INFORMATION __________________________________________________________________________

Rectifying minor problems

Not every picture or sound problem is caused by a defect in your DVD Micro System. Defects can also be caused by leads having been accidentally pulled out, damaged discs and worn out batteries in the remote control. If the following measures do not do not rectify the problem, consult your authorised dealer.

Due to the difference in quality of the recording media and the quality of the recording itself, it can occasionally happen that a home-made disc cannot be read. This does not indicate a malfunction of the DVD Micro System.
