Servicehinweise

Achtung: ESD-Vorschriften beachten 

Vor Öffnen des Gehäuses Netzstecker ziehen.

Um die hochfrequenztechnischen Vorschriften wie z.B. Störstrahlung,
Störleistung, Oszillatordrift, Einhaltung der Bild- und Tonnormen zu
gewährleisten, werden die Kassetten in der Fertigung mit großem
computerunterstütztem Messgeräteaufwand abgeglichen.
Auch bei der Reparatur müssen nach jedem Eingriff in die Kassette alle
Parameter kontrolliert bzw. eingestellt werden.
Deshalb sind die Kassetten nur als Tauschteil erhältlich,  die
Schaltung und der Abgleich der verschiedenen Kassetten mit Tuner
und Modulator nicht veröffentlicht.
Auch werden für diese Kassetten keine Ersatzteile bevorratet.

Nach Austausch einer Kassette muss der Ausgangspegel mit
dem jeweiligen Pegelsteller am Ausgangssammler an die An-
tennenanlage angepasst werden.

Service Hints

Attention: Observe the ESD safety regulations 

Disconnect the mains plug before opening the set.

To ensure the compliance with the regulations valid in the field of high-
frequency engineering, for example concerning interference radiation,
interference power, oscillator drift, picture and sound standards, the
cassettes are adjusted in the factory using a multitude of computer-
aided measuring instruments.
On carrying out repairs within the cassette all parameters must be
checked and adjusted if necessary.
That is why the cassettes are available only as an exchange part.
Therefore we refrain from publishing the circuit diagram and alignment
procedures of the different cassettes with tuner and modulator.
Spare parts for these cassettes are not kept in stock either.

On replacement of a cassette the output level must be adjusted
with the respective level control at the collective output to match
with the antenna system.
