Getting started
- Open the battery compartment cover (6) and insert a battery according to the correct polarity. Close the cover.
Calibration
- Place the device flat against any surface that is free of studs, metal and AC cables. Press and hold the Power/Scan button (5) until the red (1) and green (4) indicators flash and the beeping sound is heard. The calibration is complete when the green light is on. Do not move the device until the calibration is complete. Wait for 3 seconds after the calibration is complete before using the device.
- Calibration must be done every time the device has been turned on for use.
Usage
- Complete the calibration and place the device flat against the examined surface. Press and hold the Power/Scan button (5) and slowly move the detector across the surface in the direction you want to scan.
- When the device detects the edge of a stud, signal strength indicators (2, 3) light up. Mark the point where the center indicator (1) flashes red. Start moving the device in the opposite direction and then mark where the center indicator (1) lights up again. The two marked points indicate the edges of a stud, and the midpoint of the marks indicates the center of the stud.
- If you are receiving erratic scanning results, it may be a result of humidity, moisture within the wall cavity or drywall, or recently applied paint or wallpaper that isn’t fully dried.
Low battery indicator
- If the battery status indicator (4) starts flashing, immediately change the battery.
