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 like
the chassis, mains switch panel, keyboard control panel, picture tube
panel, deflection unit, loudspeaker and so on.
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 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!
Allgemeiner Teil
Allgemeine Hinweise
Vor dem Öffnen des Gehäuses zuerst 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 Koppelkonden-
sator 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!

Information pour la maintenance
Dèmontage de chassis
Avant de défaire les connecteurs du châssis princip, il y a lieu de
repérerauparavant les liaisonscorrespondant à chaqueplatine comme
par exemple le C.I. Inter secteur, le C.I. Commande, le C.I. Tube, le
bloc déviation ou les haut-parleurs.
A la fin de l'intervention, les connexions doivent être remises dans leur
position d'origine afin d'éviter par après d'éventuelles défaillances ou
perturbations.
Cable dereseau
Ces appareils ne peuvent être utilisés qu ' avec un cable de connecion
original de réseau avec bobine antiparasite intégré dans la fiche de
secteur. Ce câble de réseau empêche des perturbations de réseau et
est partie de l'autorisation d'appareil. Si nécessaire commandez
uniquement le cable de réseau selon la liste de pièces détachées.

Nota di servizio
Smontaggio del telaio
Prima di sfilare i cavi di collegamneto col telaio è necessario osservare
la disposizione originaria degli stessi verso le singole parti come la
piastra alimentazione, l'unità comandi, la piastra cinescopio, il giogo o
l'altoparlante.
Dopo la riparazione è necessario che gli ancoraggi e le guide
garantiscano la disposizione dei cavi analogamente a quella data in
fabrica e ciò per evitare disturbi o danni nel tempo.
Cavo rete
Gli apperechi devono essere messi in funzioni solo con il cavo originale
il colle gamento di rete e la sua spina di rete deve essere munita di una
bombina d´induttanza. In causa di sostituzione ordinate solo il cavo di
alimentatore che corrésponde alla lista degli accessori.

Nota de servicio
Desmontaje del chassis
Antes de desconectar las conecciones del Chassis hay que observar
ladireccióndedichasconecciones alos distintosgrupos deconstrucción
como la placa de conmutación de red, unidad de control, placa del
zócalo del tubo de imagen, unidad de deflección o altavoces.
Después de haber realizado la reparación y para evitar fallos o
pertubaciones posteriores es necesario reponer las conecciones tal
como fueron instaladas originalmente en fabrica.
Cable de red
El aparato solo se puede usar con el cable de red original con choque
antiparásito integrado en el enchufe de red. Este cable de red evita
perturbaciones de la red y es parte de la autorización del aparato. En
caso necesario puede pedir el cable de red según lista de piezas de
repuestos.
Sicherheits-Hinweise
Die in den Fernsehgeräten auftretende Röntgenstrahlung entspricht
den Bestimmungen der Physikalisch-Technischen Bundesanstalt vom
8. Januar 1987.
Die Hochspannung für die Bildröhre und die damit auftretende
Röntgenstrahlung ist abhängig von der exakten Einstellung der Netzt-
eilspannung +B.
Nach jeder Reparatur im Netzteil oder in der Horizontalablenkung ist
die Hochspannung zu messen und gegebenenfalls einzustellen.
Schutzschaltungen im Gerät dürfen nur kurzzeitig außer Betrieb ge-
setzt werden, um Folgeschäden am Chassis oder an der Bildröhre zu
vermeiden.
Beim Austausch der Bildröhre dürfen nur die in den Ersatzteillisten
vorgeschriebenen Typen verwendet werden.
Safety Advices
The X-radiation developing in the sets conforms to the X-radiation
Regulations (January 8, 1987), issued by the Physikalisch-Techni-
sche Bundesanstalt (federal physiotechnical institution).
The high tension for the picture tube and thus the developing X-
radiation depends on the precise adjustment of the +B power supply.
After every repair of the power supply unit or the horizontal deflection
stage it is imperative that the EHT for the picture tube is checked and
re-adjusted if necessary.
To avoid consequential damages to the chassis or the picture tube
the integrated protective circuits are allowed to be put out of operation
only for a short time.
When replacing the picture tube use only the types specified in the
spare parts lists.
