Safety warning

Warning Use the detector only to detect hidden materials behind walls and floors. The device will primarily detect live electrical wires; dead wires may not be detected. The detection results may be affected by wall construction, moisture, metal objects, and other sources of interference. If possible, always turn off the power supply before drilling or cutting and follow proper safety precautions. Do not rely on the detector as the sole means of confirming that the area is safe.
