Operating Instructions
Battery Replacement
Open the battery door on back of unit and connect a 9-volt battery to clip.
Place battery back into case and snap battery door on. Recommended to replace with a new 9-volt battery
when low battery indicator is on.
Calibration
Calibrate the unit on wall before scanning for wood or metal stud.
Note: While calibrating, the unit must not be placed directly over a stud, dense material such as metal, wet or
newly painted areas, as this will prevent the unit from calibrating properly. If this is done over wood or metal
stud, the unit will give no indication when moved away from the area. Move to a different location and try
again.
1. Hold the unit flat against the surface, making firm contact. Press
and hold the "On" button. All indicators on the LCD are displayed
while the unit goes through its' 1 to 3 second calibration cycle.
When calibrated, a beep will sound and LCD will indicate, as shown on illustration 1.
2. Press the laser key and hold the "On" button; then the laser line will always be on.
3. Keep holding "On" button during the stud detection.
USAGE
Detecting Wood Studs
Wood Stud detection is set by default when the unit is on.
1. Slide the unit across the surface in a straight line. The closer the unit is to the stud the more bars will be
shown, as illustration 2. When the stud edge is detected the Wood indicator and the edge bar will be shown,
as illustration 3 and the unit will sound a repeating beep.
2. Use the indicator line to mark the stud edge.
3. Continue sliding past the stud. When the indicator turns off and the unit stops beeping, the other edge has
been detected.
4. Double check stud location by coming back from the other direction. Make additional markings.

5. The midpoint of the marks indicates the stud center
Detecting Metal Studs
1. Press "Metal" button once and the LCD will be as shown. Press & keep holding the "On" button all the time
during the stud detection
2. Repeat the procedures 1-5 as described in" Detecting Wood Stud".
Detecting Live Wires
The Live Wire Detection feature is always on and the "Live Wire" icon will be displayed on the LCD. When a
Live Wire is detected, the red live wire LED indicator will be on. Static electricity charges that can develop on
drywall and other surfaces will spread the voltage detection area many inches to each side of the actual
electrical wire. To aid in locating the wire position, scan holding the unit 1/2 inch away from the wall surface or
place your other hand on surface approximately 12 inches from sensor.
Warning: shielded wires or live wires in metal conduits, casings, metallized walls or thick, dense
