Trouble shooting
Many problems have a simple cause and a correspon-
dingly simple solution. The following section describes a
few difficulties you may encounter, and the measures you
need to take to cure them.
If you find it impossible to solve a problem with the help of
these notes please disconnect the unit from the mains
and ask your authorised
 specialist dealer for advice.
Problem: Machine does not switch on (green
LED does not light up).
Cause 1: Mains lead not plugged in correctly.
Remedy:
Check connection, push connector in
firmly.
Cause 2: Mains fuse burned out.
Remedy: Have the mains fuse in the mains input
socket replaced by an authorised specia-
list workshop. The rating of the replace-
ment fuse must agree with the specifica-
tion printed on the unit.
Problem: The unit does not respond to com-
mands.

Static discharge or powerful interference
(e. g. lightning) have corrupted the pro-
cessor memory.

1 minute and re-connect. Switch unit on
again.
Problem: Machine responds correctly to manual
operation of the buttons, but does not
respond to remote control commands.

8 metres.
Position the receiver in such a way that it
is not subjected to direct sunlight or strong

mote control commands after you fit
new batteries in the remote control
