The control panel of a <1 MeV system must have:
- (1) an indication of whether electrical power is available at the control panel and if activation of the x-ray tube is possible;
- (2) an indication of whether x-rays are being produced;
- (3) means for indicating x-ray tube potential and current;
- (4) means for terminating an exposure at any time;
- (5) a locking device which prevents unauthorized use of the x-ray system; and
- (6) for post-1989 systems, a positive display of specific filters in the beam.
