Special Safety Precautions

The only potential source of X-Radiation is the CRT. When the high voltage circuitry is operating properly, there is no possibility of an X-Radiation problem. Keep the high voltage at the factory-recommended level of 26 kV. This voltage must not exceed 29 kV at zero beam current at rated voltage.

See Adjustments chapter for checking and adjusting high voltage.
