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.

OPERATION

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.
