X-Ray Warning

The source of X-RAY RADIATION in this TV
receiver is the High Voltage Section and the
Picture Tube.
For continued X-RAY RADIATION protection,
the replacement tube must be the same type
tube as specified in the Replacement Parts List.

To determine the presence of high voltage, use
an accurate high impedance HV meter.

Adjust brightness, color, contrast controls to
minimum. Measure the high voltage.
The meter reading should indicate

23.5 ± 1.5KV: 14-19 inch, 26 ± 1.5KV: 19-21
inch, 29.0 ± 1.5KV: 25-29 inch, 30.0 ± 1.5KV: 32
inch. If the meter indication is out of tolerance,
immediate service and correction is required to
prevent the possibility of premature component
failure.
