General Section
General Notes
Before opening the cabinet disconnect the mains plug!
Attention: Observe the ESD safety regulations
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
Whenmakingmeasurementsonsemi-conductorswithanoscilloscope,
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 approxi-
mates!
Allgemeiner Teil
Allgemeine Hinweise
Vor dem Öffnen des Gehäuses den Netzstecker ziehen!
Achtung: ESD-Vorschriften beachten
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
Bei den in den Schaltplänen angegebenen Messwerten handelt es
sich um Näherungswerte!

warranty claims. For this reason, GRUNDIG is obliged to generally
refuse any payment due to such infringements. In such cases, the
repair costs are at the charge of the retailer or the final customer, even
within the period of warranty.
