5.2 Metaldetektion
- Hold the detector by the handle and sweep the detection head evenly over the area to be scanned.
- When a metallic object is detected, the red LED indicator will light up, and the device will either emit an audible alarm or vibrate, depending on the selected mode.
- Move the detector slowly to pinpoint the exact location of the metallic object. The alarm signal will be strongest when the detection head is directly over the object.
5.3 Følsomhedsjustering
The Walfront GC-101H features adjustable sensitivity. Refer to the device's specific controls for adjusting sensitivity. Typically, a higher sensitivity setting allows for the detection of smaller or more deeply embedded metallic objects, while a lower setting can help reduce false alarms in areas with high metallic interference.

7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Enheden tænder ikke. | Batteriet er dødt eller forkert installeret. | Udskift 9V-batteriet, eller sørg for, at det er installeret med korrekt polaritet. |
| No metal detection. | Sensitivity is too low; object is too small or too deep. | Increase sensitivity. Ensure the detection head is close to the object. |
| False alarms or erratic behavior. | High electromagnetic interference; sensitivity is too high. | Move away from sources of interference. Decrease sensitivity. |
| Yellow LED (low battery) illuminates frequently. | Batteriet er ved at være afladet. | Replace or recharge the 9V battery. |
