Attention: Observe the ESD safety regulations Carrying out Measurements When making measurements on semi-conductors with an oscillo- scope, 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 The measured values given in the circuit diagrams are approximates! Allgemeiner Teil Allgemeine Hinweise Vor dem ffnen des Gehuses zuerst den Netzstecker ziehen! Achtung: ESD-Vorschriften beachten Durchfhren von Messungen Bei Messungen mit dem Oszilloskop an Halbleitern sollten Sie nur Tastkpfe mit 10:1 - Teiler verwenden. Auerdem ist zu beachten, dass nach vorheriger Messung mit AC-Kopplung der Koppelkonden- sator des Oszilloskops aufgeladen sein kann. Durch die Entladung ber das Messobjekt knnen Bauteile beschdigt werden. Messwerte Bei den in den Schaltplnen angegebenen Messwerten handelt es sich um Nherungswerte!

On completion of the repairs the leads must be laid out as originally fitted at the factory to avoid later failures or disturbances. Leitungsverlegung Bevor Sie die Leitungen und insbesondere die Masseleitungen lsen, muss die Leitungsverlegung zu den einzelnen Baugruppen beachtet werden. Nach erfolgter Reparatur ist es notwendig, die Leitungsfhrung wieder in den werkseitigen Zustand zu versetzen um evtl. sptere Ausflle oder Strungen zu vermeiden.
