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 metal detector must be IN MOTION, 

sweeping across the target  area, to detect

the presence of metal.

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:

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

Scanning Personnel in security situations should be properly trained and supervised.

This detector will not detect non-metallic objects.

DETECTOR FEATURES

1. Quick-Change Battery Compartment

Use a coin or screwdriver to open compartment.
Insert circular cam lock and twist to secure in closed position.

2. All Metal Detection

Detects all types of metals.
Will not detector non-metallic objects or weapons that do not contain metal.

3. Momentary Low Detection

While holding down the "Momentary Low" switch, the detection range will be reduced.

a) Very small metal objects, such as the metal rivets sewn into clothing, will not be 

detected beyond a range of one inch from the object.
