CALIBRATION AND SCANNING

•With WallTech™ turned off, position the unit flat against the wall.

•Press On/Off button on the side of unit and hold in still position for approximately 4 seconds until beep sound stops.This indicates successful calibration.

•To start scanning, continue to hold the On/Off button and slowly slide unit horizontally across the wall, right or left. As you begin to approach a stud, the

LED’s will light successively, from bottom to top.

•When the top red LED is lit, a continuous beep is generated.This indicates the edge of the stud. Mark this spot.

•Continue scanning beyond the marked spot until the LED’s go out. Slide unit in reverse direction to locate the other edge of stud.

•Mark this second spot. Middle of stud is centered between the two marks.

NOTE: Because of the powerful scanning capability of this tool, be sure to mark the two edges of the stud.The two marks may indicate wider than actual stud width, but center of stud will be between the two marks.

VERIFYING IF THE UNIT WORKS

• Turn WallTech™ on in the air. If the LEDs light when you bring your hand up to the back, then the unit is working properly.

WORKING WITH DIFFERENT

MATERIALS

The WallTech™ is designed for use on dry interior walls only.Three primary factors can affect sensing depth: Thickness, density and moisture content.

The WallTech™ is not designed to use on materials with inconsistent density such as:

Ceramic floor tile

Carpeting and padding Wallpaper with metallic fibers

Freshly painted walls, not completely dry

Lath and plaster

OPERATING NOTES

Depending on the proximity of electrical wiring or pipes to the wall surface, the WallTech™ may detect them in the same manner as studs. Caution should always be used when nailing, cutting or drilling in walls, floors and ceilings that may contain these items. To avoid plumbing, electrical, etc., remember that studs or joists are normally spaced 16” (406 mm) or

24” (610 mm) apart and are 1-1/2” (38 mm) in width. Anything closer together or a different width may not be a stud, joist or firebreak. Always turn off the power when working near electrical wires.
