Vor dem Öffnen des Gehäuses zuerst den 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.
Durchführen von Messungen
Bei Messungen mit dem Oszilloskop an Halbleitern sollten Sie nur
Tastköpfe mit 10:1 - Teiler verwenden. Außerdem ist zu beachten, dass
nach vorheriger Messung mit AC-Kopplung der Koppelkondensator
des Oszilloskops aufgeladen sein kann. Durch die Entladung über
das Messobjekt können Bauteile beschädigt werden.
Messwerte und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!
Austausch des Feature-Modul
Nach Austausch des Feature-Modul müssen alle Einstellungen im
Service Mode nach Tabelle "Grundeinstellwerte" (Punkte 1 und 2 im
Kapitel "Service- und Sonderfunktionen" auf Seite 2-5) eingestellt
werden.

General Section
General Notes
Attention: Observe the ESD safety regulations
Before opening the cabinet disconnect the mains plug!
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.
Carrying out Measurements
When making measurements on semi-conductors with an oscilloscope,
ensure that the test probe is set to 10:1 dividing factor. If the previous
measurement was made on AC input, please note that the coupling
capacitor in the oscilloscope will be charged. Discharge via the item
being checked can damage the components.
Measured Values and Oscillograms
The measured values given in the circuit diagrams and oscillograms
are approximates!
Change of the Feature Module
After changing the Feature Module all settings in the service mode
must be done according to the table "Basic Settings" (points 1 and 2
in chapter "Service and Special Functions" on page 2-5).
