Method to use:

 

1.Turn on the power switch (2). If a click sound is heard,it indicates that the power has been connected,and the green LED will turn on at the same time . if no click sound is heard, it indicates that no battery has been installed or the battery is not well connected .If the click sound is heard one after another it indicates that the battery cannot be used any more and a new battery shall be installed

 

2.When the switch-on click sound stops , the highly sensitive detection can be performed.Grasp the handle and detect wich the detection face around the object being detected ,there will an alarm when a metal object is detected .in the mean time ,the green LED will turn into red .when the detection stops ,the alarm stops and the red LED turns into green

 

Sensitivity Adjustment:

 

 

1.The sensitivity shall be adjusted when performance instability is observed or sound is produced when detecting human body without any metal stuff because the detection distance is less than the stipulated requirement or the sensitivity is too high

 

2.Insert a small straight-shaped screwdriver into the small hole of the handle of the detector and rotate clockwise, until a sound is head, then rotate counter-clockwise barely to the position where no sound is produced ,then rotate for another half a circle , until the sensitivity meets the requirement
