4. Usage Method:

1. Press the power switch (8), and you will hear a 'tat' sound or feel a vibration, indicating that the power is on and the green light is lit. If there is no sound or vibration, it means there is no battery or the battery contact is poor. If the alarm continues to sound continuously, it means the battery is no longer usable and a new battery should be replaced.

2. After the start-up sound stops, you can proceed with high sensitivity detection. Hold the handle and sweep the detection surface around the object to be measured. When there is a metal object, an alarm will be triggered, and at the same time, the green light will turn red. When the scanning stops, the alarm will cease, and the red light will turn green.

3. Low Sensitivity Test: If you need to exclude small objects in metal objects, you can press the low sensitivity switch (3). Scan the surrounding objects, and when metal is detected, an alarm will be triggered, and the green light will turn red. When the scanning stops, the alarm will stop, and the red light will turn green. Because the sensitivity is reduced by more than 5 times at this time, the general metal objects detected at this time are relatively large.

Five, Attention:

1. After use, please remember to turn off the power.

2. If the detector is not used for a long time, remove the battery to avoid battery leakage, which could cause serious damage to the detector. When the battery power is low, please replace or charge the battery in time to avoid false alarms.

3. When the probe is fixed facing a metal object, no alarm will occur, but only when it sweeps over the metal does it emit a sound or vibration alarm.

4. When charging, please turn off the power switch (8).

5. Charger Voltage: AC 9V; DC 10V.

6. Please use rechargeable batteries when charging, and do not charge disposable batteries. (Charging requires optional accessories).
