Einführung
Diese Service-Manual-Ergänzung dokumentiert weitere Geräte, die
mit Chassis SE ausgestattet sind.
Hinweis:
Grundlage für den Service sind folgende Service Manuals:
– Service Manual Sicherheit, Materialnummer 720108000001
– Service Manual Chassis SE, Materialnummer 720100538000
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.

Introduction
This Supplement of Service Manual describes variants of alternative
devices embedded with chassis SE.
Note:
Basic instructions for servicing are given in following Service Manuals:
– Service Manual Safety, Part Number 720108000001
– Service Manual chassis SE, Part Number 720100538000
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" –>
"HOTEL" –> + "AVAIL".
Maximum volume: " i " –> "8500" –>
3 / 4 "HOTEL VOLUME" –> +/- Value 0…63.
Switching off the activated Hotel Mode temporarily
At this function the activated hotel mode is deactivated until the set
is switched off (standby).
Call up: " i " –> "4658"
