Notes:
1. If the sensitivity is set too high, the device may continuously alarm. Adjust the sensitivity down if needed.
2. Turn off the power after use. Do not remove the battery for long periods to avoid damaging the circuit.
3. The probe may produce a crackling sound when near metal, but it will stop only when the metal continues to move.
4. When turned on, if the green light turns off and a continuous alarm sounds, the battery voltage is low. Replace the battery immediately.
