INTRODUCTION
This manual is written as a guide to help Biomedical Technicians and X-ray Servicepersons become familiar
with TXR X-ray Control theory and circuitry. Those not trained in x-ray technology including electrical and
radiation safety should not attempt repair of x-ray equipment. When covers are removed, persons will be
exposed to Lethal voltages that exists throughout the entire circuitry of the equipment and they may be
exposed to cumulative doses of x-radiation.
This manual is one of a series of manuals provided with the x-ray system and should be used as a combined
approach to operating, testing, calibrating and validation by documenting results. The series of manuals
include: M-2008-7-12, M-2008-7-13, M-2008-7-14 and M-2008-7-15. Schematics are located in manual
M-2008-7-13.
