General Notes
Attention: Observe the ESD safety regulations
Before opening the cabinet disconnect the mains plug!
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.
Measured Values and Oscillograms
The measured values given in the circuit diagrams and oscillograms
are approximates!
