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 Leitungs ver legung 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 Halb leitern sollten Sie nur
Tast köpfe mit 10:1 - Tei ler verwen den. Außerdem ist zu beachten, dass
nach vorheriger Messung mit AC-Kopp lung der Koppelkondensator
des Oszillo skops auf geladen sein kann. Durch die Ent ladung über das
Messobjekt können Bau teile beschä digt werden.
Messwerte und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!
Kindersicherung
Mit folgenden Master-Kennwörtern bekommen Sie Zugriff zum Ändern
verlorener Kennwörter:

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
When making measurements on semi-con duc tors 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 and Oscillograms
The measured values given in the circuit diagrams and oscillograms
are approximates!

Geräte- und Display-Varianten
Display- und Product Code
Je nach Verfügbarkeit werden
Displays verschiedener Hersteller
eingebaut. Dies führt zu unterschiedlichen Chassis-Bestückungen, sowie zu Änderungen
in der Software. Bei Ersatzteilbestellungen und SoftwareUpdates achten Sie bitte auf das
eingebaute Display, sowie auf den
"Product Code". Angaben dazu
finden Sie auf der Geräterückseite. Sollte in der Ersatzteilliste
des Service Manuals Ihr "Product
Code" oder Ihre Display-Variante
nicht aufgeführt sein, können Sie
eine aktualisierte Version auf
dem GRUNDIG Service-Portal
"http://service.grundig.de" finden.
Überprüfen Sie vor PlatinenTausch, ob die Aufkleber der
Platinen identisch sind (z.B. PCB
Code).

Display- und Product Code
Depending on availability displays
of different manufacturer are built
in. This results in different chassis
mountings as well as a different
software. On spare parts orders
as well as software updates take
care of the fitted display as well as
of the "Product Code". Therefore
you can find information on the
labels on the rear side. If your
"Product Code" or display variant is not mentioned in the spare
parts list of the service manual,
please look for a current version
at the GRUNDIG service portal
"http://service.grundig.de".
Before changing any board please
check whether the labels on the
boards are identical (eg. PCB
Code).
