Upon release of the "Momentary Low" switch, the detector will return to Normal Operation.

4. Silent Operation

Position the Silent/Audio switch in the "Silent/Vibrate" position and:

a) The detector will NOT emit the High-Pitch tone upon the detection of metal objects.
b) The vibrator will activate upon the detection of a metal object, and the "Target" 

LED indicator will illuminate.

5. Operating Frequency Selection

Chose from two alternate operating frequencies in the event of electromagnetic 
interference from other electronic devices.

6. Low Battery Indication

When battery needs to be replaced, Low Battery LED will illuminate.

7. Visual Target Response

8. Comfort Hand Grip 

Power Switch with Momentary Low

The Power switch has 2 "ON" positions and a forward "OFF" position.

The detector is OFF with the switch in the "UP" position

The detector is ON with the switch in the "MIDDLE" position

The detector is in MOMENTARY LOW operation with the switch 
held in the "DOWN" position.

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.

b) Large environmental metal objects, such as the metal reinforcing bars in floors, 

will not be detected beyond a range of several inches.

Upon release of the "Momentary Low" switch, the detector will return to Normal Operation
