X-RADIATION
WARNING
1. The potential source of X-radiation in EVF sets is the High Voltage
section and the picture tube.
2. When using a picture tube test jig for service, ensure that jig is
capable of handling 10kV without causing X-Radiation.
Note :
It is important to use an accurate periodically calibrated high voltage meter.
3. Measure the High Voltage. The meter (electric type) reading
should indicate 2.5kV, ± 0.15kV. If the meter indication is out of
tolerance, immediate service and correction is required to prevent
the possibility of premature component failure. To prevent an X-
Radiation possibility, it is essential to use the specified picture
tube.
