Body Scanning for the Detection of
Metal Objects
Always test the detector before operation. Sweep the detector across a known
metal object, and verify detection with audio, vibratory, and visual feedback.
Motion is Required:
The subject should stand upright, with arms and legs extended.
Sweep the detector over the subject, with a smooth, even motion, about one inch from the body.
Avoid making physical contact between the subject and the detector.
Press and Hold the "Momentary Low" switch to eliminate interference from the metal bars in
floors, or from very small metal objects, such as rivets or zippers sewn into clothing.
CAUTION:
Scanning Personnel in security situations should be properly trained and supervised.
This detector will not detect non-metallic objects.
The metal detector must be IN MOTION,
sweeping across the target area, to detect
the presence of metal.
Use in the MOMENTARY LOW mode will desensitize the detector.
Use the Momentary Low switch only after the detection of metal, and the
verification of the absence of a larger metal object
