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 und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!
Kindersicherung
Mit der Master-Pin "1453" kann die Einstellung der persönlichen Pin
geändert werden.
Hotel-Mode
Bei aktivierter Funktion ist die maximale Lautstärke begrenzt und das
Menü "Installation" ist nicht mehr anwählbar.
Aufruf: " i " –> "8500" –> 3 / 4 "OPTION 1" –> OK ( ) –> 3 / 4 "HOTEL" –> + "AVAIL".
Maximale Lautstärke: " i " –> "8500" –> 3 / 4 "OPTION 1" –> OK ( )
–> 3 / 4 "HOTEL VOLUME" –> +/- Wert 0…63.
Spare Parts Lists .................................. 3-1…3-3
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
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!
Parental Control
The personal pin can be changed with master pin "1453".
Hotel Mode
Maximum volume is limited and there is no access to Menu "Channel
Setup" at activated hotel mode.
Call up: " i " –> "8500" –> 3 / 4 "OPTION 1" –> OK ( ) –> 3 / 4
"HOTEL" –> + "AVAIL".
Maximum volume: " i " –> "8500" –> 3 / 4 "OPTION 1" –> OK ( ) –>
3 / 4 "HOTEL VOLUME" –> +/- Value 0…63.

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 Software-Updates 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 Austausch der
Hauptplatte, ob die Aufkleber der
Platinen identisch sind.
Product and Display Variants
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 the main board
please check whether the labels
on the boards are identical.
