WARNING: To reduce the risk of injury, user must read and understand instruction
SAVE THESE INSTRUCTIONS
• Do not operate the stud sensor in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust.
• Use the stud sensor only with the specifically designated batteries. Use of any other
batteries may create a risk of fire.
CAUTION: Use caution when drilling, nailing or cutting into walls, floors and ceilings which
may contain electrical wiring or pipes. These items may be detected by the Stud Finder in
the same manner in which studs are detected. Because studs are normally spaced 16
inches or 24 inches apart and are 1-1/2 inches wide, beware of anything closer together or
of a different width. Always turn off the power when working near electrical wires.
INSTALLING THE BATTERY
Remove the battery compartment cover (D) by pressing down in the center of the cover and
pulling back. Insert two fresh AA batteries making sure to match (+) and (-) terminals
correctly. Replace the battery compartment cover.
CALIBRATION AND SCANNING
1.) Hold unit straight up and down and place flat against wall as shown in Figure 2.
2.) Press in and hold the stud sensor ON/OFF button (C).
a.) The upper red LED (A) will light,
b.) The unit will beep once while it is calibrating,
c.) The bottom green LED (B) will light.
3.) Slide sensor slowly, (Figure 3,) horizontally across surface of wall without lifting or tilting.
4.) The upper red LED will light and a beeper will sound when an edge is detected , mark
that spot (Figure 4).
Repeat this cycle coming from the other direction and again mark the spot where the upper
red LED lights and beeper sounds.
Measure between the two marks made on the wall and the center will coincide with the
center of the stud.
TIPS FOR OPTIMUM USE
• Test batteries before each use. Press and hold the on/off switch until the green LED lights.
Then move your free hand toward the back of the unit. The red light should illuminate and
then go out as you move your hand away from the unit. Replace the batteries if the red LED
does not illuminate.
• Hold stud sensor straight up and down.
• Because studs are normally spaced 16 inches or 24 inches apart and are 1-1/2 inches
wide, beware of anything closer together or of a different width. Doors and windows are
constructed with studs and headers which are closer together.
• Metal or wood studs can be detected through up to 3/4" drywall.
• Avoid materials which have inconsistent density such as:
• Carpeting and padding
• Ceramic floor tile
• Wallpaper containing metallic foils or fibers. Generally, surfaces covered with regular
wallpaper or fabric will scan with no difference in function.
• Walls that are freshly painted and are still damp.
• Excessively thick plaster and lath.
Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.
IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and
adjustment (other than those listed in this manual) should be performed by authorized
