X-RAY

This receiver is designed so that any X-Ray radiation is kept to an absolute

minimum.

Since certain malfunctions or servicing may produce potentially
hazardous radiation with prolonged exposure at close range, the following
precautions should be observed:

When repairing the circuit, be sure not to increase the high voltage to more than 27.3kV, (at

1.

cut-off) for the set.
To keep the set in a normal operation, be sure to make it function on

If there is a possibility that the high voltage fluctuates as a result of the repairs, never
forget to check for such high voltage after the work,

DO not substitute a picture tube with unauthorized types and/or brands which may cause

excess X-ray radiation.

-Adjusted to the above-mentioned high voltage.
