1. Material: ABS2. Applicable to airports, stations, docks, customs, public security, border defense, security departments, sports ground security inspections or any other occasions where you need confidentiality and security3. When metal is detected, it will make a high-pitched sound and glow4. It can also be used for precious metal detection, such as gold and silver jewelry, etc.5. Simple and convenient to use, no need to adjust, two options of high and low sensitivity6. Alarm mode with sound and vibration7. There is an automatic continuous sound or vibration alarm when the battery is exhausted, and there is an external charging jack8. Test distance for metal objects: 10mm for a pin, 60mm for a 1-yuan coin, 120mm for a 6-inch wrench9. Power-on detection: Turn on the power switch and hear a clicking sound for about 3-5 seconds, indicating that the power is turned on, the self-test time is over, and it can be used normally10. At the same time, the green light is on: if the green light is off, it means that the battery is not installed or the battery is in poor contact; if the continuous sound or continuous vibration or no call, it means that the battery can no longer be used, and a new battery should be replaced (not included)High-sensitivity test: After turning on the power, high-sensitivity detection can be performed. Hold the handle to scan the detection surface around the object to be tested. When there is a metal object, an alarm sound or vibration will be issued, and the green light will turn into a red light; stop scanning. , the alarm sound or vibration will stop, and the red light will turn to green11. Low-sensitivity test: If you need to exclude small objects in metal, you can press and hold the low-sensitivity switch to scan around the object to be tested. When there is a metal object, an alarm sound or vibration will sound, and the green light will change to Red light; stop scanning, the alarm sound or vibration will stop, and the red light will turn to green light. Because the sensitivity is reduced by more than 5 times at this time, the detected metal objects are generally relatively large at this time.12. Sensitivity adjustment: If the detection distance does not meet the specified requirements or the sensitivity is too high to cause instability or sound or vibration is emitted to the human body without metal scanning, the sensitivity should be adjusted, and the sound and vibration switch should be placed on the release. state, use a small flat-blade screwdriver to insert it from the hole on the detector handle and rotate it counterclockwise until it emits sound, then turn it counterclockwise until no sound is heard, and then turn it half a circle clockwise until the sensitivity meets the requirements.13.
