Servicehinweise
Achtung: ESD-Vorschriften beachten
Vor Öffnen des Gehäuses Netzstecker ziehen.
Leitungsverlegung
Bevor Sie die Leitungen und insbesondere die Masseleitungen lösen,
muss die Leitungsverlegung zu den einzelnen Baugruppen beachtet
werden.
Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder
in den werkseitigen Zustand zu versetzen um evtl. spätere Ausfälle
oder Störungen zu vermeiden.
Service Hints
Attention: Observe the ESD safety regulations
Disconnect the mains plug before opening the set.
Wiring
Before disconnecting any leads and especially the earth connecting
leads observe the way they are routed to the individual assemblies.
On completion of the repairs the leads must be laid out as originally
fitted at the factory to avoid later failures or disturbances.
