X-radiation Exposure
The X-ray tube assembly produces X-radiation when energized. Never operate this device without X-ray
shielding in place. Use lead shielding and draping to protect personnel.
Lead aprons, radiation monitors, and appropriate radiation shields must be utilized for
the protection of all personnel in the vicinity while performing tests. Living human
anatomy should never be used as a phantom or demonstration aid. Do not produce
radiation in hallways.
Many of the PCB's in this system contain components, which are sensitive to Electro-
Static Discharge (ESD). Observe ESD safety procedures.
