OPERATION

WARNING:

Do not use any attachments or accessories not

recommended by the manufacturer of this product. The

use of attachments or accessories not recommended

can result in serious personal injury.

APPLICATIONS

You may use this product for the purposes listed below:

Locating wood or metal studs or joists

Finding general location of AC wiring

TO INSTALL/REMOVE BATTERY PACK

See Figure 2, page 9.

 Open the battery compartment door.

 Place the battery into the battery compartment.

NOTE: The raised rib on the side of the battery must be

aligned with the groove in the battery compartment.

 Reinstall the battery compartment door.

OPERATING TIPS

 Once activated, the ON button must be continuously

depressed to allow the unit to function. If the ON button

is released, you must restart the process from the

beginning.

 The unit should remain firmly against the wall surface

during the entire detection process. Hold the unit only in

the gripping areas provided.

 Once you have located a stud or AC wire, verify the

location by repeating the detection process from the

opposite side. The location of the wire or stud will

generally be at the center point between the two detected

positions.

 If using the unit on uneven or textured surfaces, place a

thin piece of cardboard between the unit and the surface.

Make sure you have the cardboard in place during both

the calibration and the detection process.

 If you are having trouble locating live wires, ground

the unit by placing your other hand against the wall

approximately 8 in. to the side of the unit. Slide your hand

along the wall as you slide the unit.

 The presence of any type of metal material or metal studs

in the detection area can cause unreliable readings.

USING THE STUD SENSOR

See Figures 3 - 4, page 9.

NOTE: The stud sensing feature of this unit is accurate

under most conditions.

 Using the dial on the front of the unit, select the detection

depth needed based on the surface being scanned.

NOTE: As a general guideline, use the 1/2 in. setting for

unpainted, painted, or wallpapered drywall. For panelled

drywall or plastered walls, use the 1 in. setting. The

1-1/2 in. setting should be used for detecting floor joists

underneath plywood.

 Place the unit against the wall and depress the ON button.

Hold the product still to allow the unit to calibrate. When

the calibration process is completed, the unit will beep

and READY will appear on the LCD display. If  symbols

are displayed instead of READY, repeat the calibration

process.

NOTE: The unit must not be placed over a stud or live

wire during the calibration process.

Locating studs or joists:

 Once calibration is complete, begin to slowly move the

unit in a straight line to the left or right against the wall.

As you near a stud, the graduated display will begin to

light up. When you reach the edge of the stud, the display

will fully light up, the word STUD will appear at the top,

and an audio signal will sound.

 Using a pencil in the groove at the top of the unit, make a

mark on the wall at the point where STUD first appeared

on the display.

 Continue to move the unit across the wall. STUD will

remain on the display until you reach the other edge of

the stud. Mark the spot on the wall just before the word

STUD disappeared from the display. These two pencil

marks show the left and right edges of the stud. The

mid-point between the marks indicates the center of the

stud.
