PATIENT SAFETY AND OTHER PRECAUTIONS
Radiation protection for intraoral radiography
WARNING
During the exposure,
nobody
but the patient should be inside the useful X-ray beam. The operator must
be at least 6 feet away from the X-ray head, and not in the direction of the radiation.
Full use of the length of the handswitch exposure cable
should be made.
WARNING
Since the Portable X-ray unit requires assembly-disassembly as same is transported from
location to location, you the USER are required to perform a power supply line adequacy
test as outlined in these instructions every time the unit is re-assembled for use and docu-
ment same on the TEST RECORD
as provided, last pages of the operating instructions.
WARNING
Visual checks must be performed before connecting the unit to an adequate power supply.
WARNING
When
the unit
is set-up
in preparation
for
Radiography
you
as the installer/assembler must verify the
following:
ir
Verify that all labels are affixed and legible. Look for mechanical damage, possibly affecting radia-
tion
safety,
(inspect
collimator
for possible cracks,
test the tubehead
in all working
positions
for
possible drift).

2.
Operating-ready light (green). Line compensation indicators (LED's). Digital line adequacy volt meter.
The operating-ready light (green)
must light up and the meter must be functional.
WARNING
Mechanical damage affecting radiation safety be evident, the user is not permitted to use the unit until re-
pairs or replacements, correcting the defect(s), are made.
Defective bulbs for
power "on" light, ready light, radiation light constitute a safety hazard to the patient as
well
as to
the operator,
therefore,
repairs or replacements
must
be made
promptly,
same
rule as above
applies.
During line adequacy tests:
WARNING
Observe radiation protection as outlined above
k
Check radiation warning light and acoustic buzzer for proper functioning.
2.
Make
sure the X-ray exposure is interrupted after releasing the exposure switch (dead man feature).
