4 സുരക്ഷാ വിവരങ്ങൾ
Please read and understand all safety instructions before operating the device. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- 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.
- Keep the device dry and clean. Do not expose it to moisture or extreme temperatures.

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.

6.1 മോഡ് തിരഞ്ഞെടുക്കൽ
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.
- മെറ്റൽ ഡിറ്റക്ഷൻ മോഡ്: 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.

Image 6.2: An illustration demonstrating the NF-5101's ability to detect wood, live AC power cables, non-magnetic metal, and magnetic metal at different depths within a wall.
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:
- Yellow Screen: Indicates the device is in calibration mode.
- Green Screen: Indicates calibration is complete and the device is ready for scanning, or no target is currently detected.
- ചുവന്ന സ്ക്രീൻ: Indicates a target has been detected.
- സിഗ്നൽ ശക്തി സൂചകം: 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.
- കേൾക്കാവുന്ന അലാറം: A 'beeping' sound will activate when a target is detected, becoming more frequent as the device approaches the center of the object.
