4. Sikkerhedsoplysninger
Læs og forstå alle sikkerhedsinstruktioner, før du bruger enheden. Manglende overholdelse af disse instruktioner kan resultere i elektrisk stød, brand eller alvorlig personskade.
- Always exercise caution when drilling, cutting, or nailing into walls, ceilings, or floors that may contain electrical wiring or plumbing.
- Do not rely solely on the detector to locate items behind surfaces. Use other available information, such as building plans, to help avoid hazards.
- Before working near detected live wires, always turn off the power to the circuit at the main breaker or fuse box.
- Hold enheden tør og ren. Udsæt den ikke for fugt eller ekstreme temperaturer.
- Do not attempt to open, modify, or repair the device. Refer all servicing to qualified personnel.
- Bortskaf brugte batterier ansvarligt i henhold til lokale regler.

5. Opsætning
5.1 Batteriinstallation
- Find batteridækslet på bagsiden af enheden.
- Skub dækslet åbent.
- Insert the included 9V alkaline battery, ensuring correct polarity (+/-).
- Luk batterirummets dæksel forsvarligt.
5.2 Automatisk kalibrering
The NF-5101 features an automatic calibration function. Upon powering on, the device will self-calibrate. A 'drip' sound prompt indicates that calibration is complete and the device is ready for use. For optimal results, ensure the device is held against the wall surface where scanning will begin, away from known studs or metal objects, during calibration.

6. Betjeningsvejledning
6.1 Valg af tilstand
The NF-5101 offers three distinct detection modes, selectable via the buttons on the device:
- Wood Detection Mode: For locating wood studs up to 1.18 inches (30mm) deep.
- Metaldetektionstilstand: For detecting magnetic metal up to 3.94 inches (100mm) and non-magnetic metal up to 3.15 inches (80mm) deep.
- AC Live Wire Detection Mode: For identifying live AC wires up to 1.97 inches (50mm) deep.

6.2 Scanning Procedure
- Press the power button to turn on the device. It will automatically calibrate.
- Select the appropriate detection mode (wood, metal, or AC live wire) using the mode selection buttons.
- Place the scanner flat against the wall surface. Ensure the sensor area on the back of the device is in full contact with the surface.
- Slowly slide the device horizontally across the surface. Maintain constant contact and pressure.
- Observe the LCD display and listen for audio alerts. The signal strength indicator will increase as the device approaches a target.
- When the device detects a target, the screen color will change, and an audible alarm will sound. A center positioning icon will appear on the screen when the center of the target is located.
- Mark the location of the detected object. For greater accuracy, scan the area from both directions and mark the edges, then determine the center point.

7. Understanding the Display and Audio Alerts
The NF-5101's HD LCD display provides visual feedback, complemented by audio alerts, to indicate detection status:
- Gul skærm: Indicates the device is in calibration mode.
- Grøn skærm: Indicates calibration is complete and the device is ready for scanning, or no target is currently detected.
- Rød skærm: Indicates a target has been detected.
- Signalstyrkeindikator: Bars on the screen show the proximity and strength of the detected object. More bars indicate closer proximity.
- Center Positioning Icon: An icon appears on the screen when the device is directly over the center of a detected object.
- Hørbar alarm: A 'beeping' sound will activate when a target is detected, becoming more frequent as the device approaches the center of the object.

10. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Inkonsekvente eller unøjagtige aflæsninger | Improper calibration; conductive wall coverings or high humidity; presence of magnetic fields or metal building materials; device not flat against surface. | Ensure proper automatic calibration away from known objects. Ensure wall surfaces are dry and non-metallic. Avoid scanning near strong magnetic fields. Maintain constant, flat contact with the wall. |
| Ingen detektion eller svagt signal | Low battery; incorrect mode selected; object too deep for selected mode. | Check battery level and replace if necessary. Verify the correct detection mode is selected for the target material. Note the maximum detection depths for each mode. |
| Enheden tænder ikke | Dødt eller forkert installeret batteri. | Check battery installation. Replace with a new 9V alkaline battery. |
