6F22N a 9-volt battery or a rechargeable battery, open the battery cover when installing the battery, battery positive and negative open note on / off switch button, the green light, then the detector can work properly. Detector sensitivity and detection range can be adjusted until the red light and a continuous alarm sound. Sensitivity adjustercounter-clockwise until the red light off the alarm sound disappeared at this time in the most appropriate detector sensitivity and detection range.

Hand-held detectors used to detect faces at the top surface of the object to be inspected 10-30 mm back and forth constantly scanning the area.
If the metal detector will issue a warning sound and a red light. When the detector to keep on top of a metal object does not move when the detection signal is automaticallyreduced, so when you use the detector to constantly scan back and forth, it is very important.

Uses:
1. Airports, railway stations, docks electronic detection checks
2. Customs, border control, defense department security checks
3. Medicine, food quality inspection business systems
