Installing the Battery

With a small tool or coin, slide the pocket clip up and off of the case.

Insert a 9-volt battery so that the minus (-) sign on the battery matches the minus (-) sign on the side of the battery compartment.

Slide the pocket clip on to the case and press it down hard until it snaps closed.

Scanning for Studs

Place the iSensor against the wall with the pocket clip near the palm of your hand and your fingers no higher than the word "Zircon" (see Figure 1).

Keeping your other hand at least 6 inches away from the iSensor, press and HOLD in the ON/OFF switch located on the left side of the iSensor.

Slide the iSensor slowly across the wall, left or right, until the LED comes on and stays on. This is the stud edge. Mark this spot.

Continue moving across the stud until the LED turns off and then, still holding the switch in, reverse direction and locate the other edge of the stud and mark it in the same way.

The midpoint of the two marks is the center of the stud.

Helpful hints:

  • 1. The position where you start is important. iSensor finds dense objects beneath the wall surface. To work right, the tool must start (by holding the button) over a part of the wall that is not dense. If iSensor seems weak or inconsistent, try starting at a new spot some distance to either side of the first. iSensor will not work if started directly over a stud, metal, wet paint or wet wallpaper.

  • 2. iSensor will only detect the outer edge of double studs and headers around doors, windows and corners.

  • 3. iSensor usually finds studs but can some-times find pipes or other objects. Be sure you've found a stud by finding other studs equally spaced to either side (16 or so inches apart), and finding the same stud at several places directly above and below the first.
    You can check that your iSensor is working by holding it in one hand and pressing in on the ON/OFF switch. While holding the switch in, bring the palm of your other hand up against the back of the iSensor. The LED should turn on. If it does not, try replacing the battery.

  • Double Stud & Solid Headers: These supporting members are usually found around doors, windows and corners. The iSensor will only detect the outer edge of this grouping.

CAUTION

If electrical wiring, metal or plastic pipes are close to or touching the inside surface of the wall, the iSensor may detect them in the same manner as studs. Caution should always be used when nailing, cutting, or drilling into walls, floors, and ceilings that may contain these items.

To avoid surprises, remember that studs are normally spaced 16 inches or 24 inches apart on center and are 1-1/2 inches in width. Anything closer together or a different width may not be a stud, or fire break.

Note: Always turn off the power if working near electrical wires.
