General Section
The X-radiation developing in the sets conforms to the X-radiation
Regulations (January 8, 1987), issued by the Physikalisch-Technische
Bundesanstalt (federal physiotechnical institution).
The high tension for the picture tube and thus the developing Xradiation depends on the precise adjustment of the +A power supply.
After every repair of the power supply unit or the horizontal deflection
stage it is imperative that the EHT for the picture tube is checked and
re-adjusted if necessary.
To avoid consequential damages to the chassis or the picture tube
the integrated protective circuits are allowed to be put out of operation
only for a short time.
When replacing the picture tube use only the types specified in the
spare parts lists.
