When the full arrow
is first displayed,
the SpotLite
®
pointer
shines, and a steady
tone sounds, you have
located the edge of the
stud. Mark this spot.
Without releasing
Power button, continue
scanning beyond
marked spot until some
segments of the arrow
turn 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
®
indicator
will appear on the display. 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
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. Wait for
beep to confirm calibration has completed before
moving scanner.
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.
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 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.
You suspect electrical
wires, but do not
detect any.
Area of voltage

larger than actual wire
(AC only).
s 7IRES MAY BE SHIELDED BEHIND
metallic wall coverings, plywood
shearwall, or other dense material,
or in conduit.
s 4HE WIRES MAY NOT BE LIVE
s 7IRES DEEPER THAN IN MM

s 4URN UNIT OFF MOVE OVER A FEW INCHES n CM
press Power button, and start again.
s /N ROUGH SURFACES PLACE A THIN PIECE OF CARDBOARD ON
