3.3 Connecting the Transmitter
Connect the transmitter unit to the main detector unit using the provided cable. Ensure a secure connection. Both units must be powered on for the system to function correctly.
4. Operating Instructions
This section details how to operate your metal detector for effective searching.
4.1 Powering On and Initial Settings
- Ensure both the main detector unit and the transmitter unit are fully charged and connected.
- Locate the Switch button on the main unit and press it to power on the device.
- On the control panel, select the desired metal type for detection (Copper, Silver, Gold, Diam - likely referring to Diamond or other precious stones) by pressing the corresponding button.
- Adjust the Range and Depth settings according to your search requirements using their respective buttons.

4.2 Detection Process
The device utilizes a remote search and positioning system. Once powered on and settings are configured:
- Hold the main unit steadily. The device will begin scanning the area.
- When a designated item is detected, the device will indicate its presence. For larger items, the amplitude of the swinging action (if applicable to the device's physical feedback) will increase.
- The microcomputer control chip unit assists in quick scanning and detection, improving efficiency.

For optimal results, operate the device in open areas without significant electromagnetic interference. Maintain a stable posture during scanning.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your metal detector.
- Cleaning: After each use, wipe down the device with a soft, dry cloth to remove dirt, dust, and moisture. Do not use abrasive cleaners or solvents.
- Storage: Store the metal detector in a cool, dry place, away from direct sunlight and extreme temperatures. Disconnect the transmitter from the main unit if storing for extended periods.
- Battery Care: If the device uses rechargeable batteries, ensure they are charged periodically even when not in use to maintain battery health. Avoid fully discharging the batteries frequently.
- Inspection: Periodically check all cables and connections for signs of wear or damage. Replace any damaged components immediately.
6. Troubleshooting
If you encounter issues with your Walfront Metal Detector, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery; loose power connection; power switch not engaged. | Ensure the device is fully charged. Check all cable connections. Confirm the power switch is in the 'ON' position. |
| No detection or inconsistent detection. | Incorrect settings (Range/Depth); environmental interference; transmitter not connected/powered. | Adjust Range and Depth settings. Move to an area with less electromagnetic interference. Verify the transmitter is connected and powered on. Ensure both units are switched on. |
| Device detects items but cannot pinpoint location. | Improper scanning technique; environmental factors. | Practice a steady and consistent scanning motion. Ensure the device is held stable without interference. |
| Display screen is blank or flickering. | Low battery; loose display connection; software issue. | Charge the device fully. If the problem persists, contact customer support. |
