General Notes

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 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.

Mains Cable

The TV receiver must only be operated with an original mains connecting cable with an interference suppressor choke integrated in the mains plug.This mains cable prevents interference from the mains supply and is part of the product approval. For replacement please order exclusively the mains connecting cable specified in the spare parts list.
