Owner's Manual
Without releasing the
Power button, continue
scanning beyond the
marked spot until the red
EDGE light turns off. Slide
unit in reverse direction to
locate other edge of stud.
Mark this second spot.
Middle of stud is centered
between the two marks.
4. WIREWARNING
®
DETECTION
WireWarning
®
detection works continuously in STUD
SCAN and DEEPSCAN
®
modes. When live AC voltage is
detected, the WireWarning
®
light comes on. If scanning
begins over a live AC wire, the WireWarning
®
indicator
will flash continuously. Use extreme caution in these
circumstances or whenever live AC is present.
Electrical field locators may not
detect live AC wires if moisture
is present in the wall, or if wires are more than 2 in.
(51 mm) from the scanned surface, in plastic conduit
or behind a plywood shear wall or metallic wall
covering. Do not rely exclusively on the detector to
locate items behind the scanned surface. Use other
information sources to help locate items before
penetrating the surface. Such additional sources include
construction plans, visible points of entry of pipes
and wiring into walls, such as in a basement, and in
standard 16 in. (41 cm) and 24 in. (61 cm) stud
spacing practices.
DO NOT ASSUME THERE ARE
NO LIVE ELECTRICAL WIRES IN
THE WALL. DO NOT TAKE ACTIONS THAT COULD
BE DANGEROUS IF THE WALL CONTAINS A LIVE
ELECTRICAL WIRE. ALWAYS TURN OFF THE
ELECTRICAL POWER, GAS, AND WATER SUPPLIES
BEFORE PENETRATING A SURFACE. FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY RESULT IN
1. INSTALLING THE BATTERY
Push in the battery door
tab at the bottom of the
tool and open the door.
Insert a new 9-volt battery,
matching the positive (+)
and negative (-) terminals
to the icons printed on
the back. Snap the battery
into place and replace the door.
2. SELECTING THE MODE
Move selector switch to the desired mode:
STUD SCAN for finding wood or metal studs or
DEEPSCAN
®
for finding studs behind walls more
than
3
⁄4 in. (19 mm) thick.
Unit will remain off if Power button is not depressed.
3. FINDING A STUD
Always scan for studs with the scanner placed flat
against the wall. Move the mode switch to STUD
SCAN, place the tool flat against the wall, then press
and hold the Power button. Do not move the unit until
calibration is complete. When calibration is complete,
the green READY light will illuminate.
Continue to hold the Power
button, then slowly slide
unit horizontally across the
wall, left or right. As you
begin to approach a stud,
the arrow segments will
begin to turn on.
When the top red EDGE
light is lit, the SpotLite
®
pointer shines, and a
steady tone sounds, you
have located the edge of
the stud. Mark this spot.
ELECTRIC SHOCK, FIRE, AND/OR SERIOUS INJURY
OR PROPERTY DAMAGE.
5. OPERATING TIPS
For optimum scanning results:
s (OLD THE TOOL STRAIGHT UP AND DOWN PARALLEL TO THE
studs, and do not rotate the tool.
s +EEP TOOL FLAT AGAINST THE WALL AND DO NOT ROCK TILT
or press hard when slowly sliding across the surface
being scanned.
s !VOID PLACING YOUR OTHER HAND OR ANY OTHER PART OF
your body, on the surface being scanned.
s $EPENDING ON THE PROXIMITY OF ELECTRICAL WIRING OR
pipes to the wall surface, the scanner 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.
s 4O AVOID SURPRISES REMEMBER THAT STUDS OR JOISTS
are normally spaced 16 in. (41 cm) or 24 in. (61 cm)
apart and are 1
1
⁄2 in. (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.
