Part IV. Sensitivity adjustment:
1. When the performance is obviously unstable or an alarm is issued when the human body does not have any metal, the sensitivity should be adjusted because the detection distance is less than the specified distance or the sensitivity is too high.
2. Use a small flat-blade screwdriver to insert the small hole in the detector handle, and slowly rotate it clockwise until the alarm stops, then rotate a half turn until the sensitivity reaches the ideal state.
