1.2 How to service
How to service
Front line service
Both the Master and the Socket Unit has been developed for simple module
exchange to follow the on-site service strategy. Module exchange is possible on-site,
at the dealer or in the service workshop whatever is most convenient in each case.
For on-site service a back-up suitcase must be used.
Module exchange is the recommended way to perform service, due to the fact
that most of the modules are multi layer based, and most of the circuits are on a
single main PCB.
An electrical fault symptom can be removed during one visit to the customers
home if you bring a BeoCenter 2 back-up suitcase with you.
Is it a mechanical symptom, the particular part must be brought with you
separately.
The Socket Unit and the Master Unit must be connected when testing, because
the Socket Unit contains the power supply.
Service documentation
Service documentation for BeoCenter 2 will be a Service Manual with part nos. for
the back-up suitcase, electrical and mechanical parts, user’s guides etc.
How to service 1.3
Converting mains voltage supply
The Master Unit has only one variant for all markets.
The Socket Unit has separate type nos. for each market, due to country approvals.
The mains voltage is determined by the type nos. of the Socket Unit, there are
only two internal mains voltage settings (a jumper) on the SMPS, 100/120V and
230/240V AC. (X103, when mounted = 100/120V).
Use the ServiceTool to reprogramme the DVD region code and tuner setup.
The only variant on the Master Unit : 2802
