Module exchange is possible on-site, at the dealershop 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

6、 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 DVD 2 Back-up suitcase with you. Is it a mechanical symptom, the s
