5. Operating Instructions

5.1 Power On/Off

Press the 'SELECT' button to turn the device on. The device will automatically power off after a period of inactivity to conserve battery life.

5.2 Selecting Detection Mode

After powering on, press the 'SELECT' button repeatedly to cycle through the three detection modes:

• Metal Detection: For locating metal pipes, rebar, or other metallic objects.
• Wood Detection: For finding wooden studs or beams.
• AC Power Detection: For identifying live AC electrical wires.

The selected mode will be indicated on the digital display.

5.3 Scanning Procedure

1. Select the desired detection mode.
2. Place the device flat against the wall surface. Ensure full contact.
3. Slowly slide the device horizontally across the wall.
4. Observe the digital display. As the device approaches a target, the signal strength indicator will increase.
5. When the device is directly over the center of the target, the signal strength will be at its maximum, and the device will emit an audible beep. Mark this location.
6. Repeat the scan from the opposite direction to confirm the edges and center of the detected object.

6. Maintenance

• Clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
• Remove the battery if the device is not used for extended periods to prevent leakage.

7. Troubleshooting

• Device does not power on: Check if the 9V battery is inserted correctly and has sufficient charge. Replace the battery if necessary.
• Inaccurate readings: Ensure the device is held flat against the wall and moved slowly. Calibrate by moving it away from any known objects before scanning. Environmental factors like humidity or wall material can affect accuracy.
• No detection: Verify that the correct detection mode is selected for the target material. Ensure the object is within the specified detection depth.
