2. X-RADIATION
WARNING :
1. The potential source of X-Radiation in TV sets is the High Voltage
section and the picture tube.
2. When using a picture tube test fixture for service, ensure that the
fixture is capable of handling 34.5 kV without causing X-Radiation.
NOTE:
It is important to use an accurate periodically calibrated high
voltage meter.
1. Reduce the brightness to minimum.
2. Set the SERVICE switch to SERVICE .
3. Measure the High Voltage. The meter reading should indicate 32.5
kV±2.0 kV.
If the meter indication is out of tolerance, immediate service and
correction is required to prevent the possibility of premature
component failure.
4. To prevent an X-Radiation possibly, it is essential to use the
specified picture tube.
