3. SELECTING THE MODE
Move selector switch to the desired mode:
STUD SCAN for finding wood or metal studs or
DEEPSCAN
than
®
for finding studs behind walls more
3
⁄4 in. (19 mm) thick.
Unit will remain off if Power button is not
depressed.
4. 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 in the
Power button then slowly
slide unit horizontally
across the wall, left or
right. As you begin to
approach a stud, the red
LED segments
will begin to turn on.
When the top green
LED is first lit,
the SpotLite
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
LEDs turn off. Slide unit
in reverse direction to
locate other edge of stud.

circumstances or whenever live AC is present.
WARNING
Electrical field locators may
not detect live AC wires if
wires are more than 2 in. (51 mm) from the
scanned surface, encased in conduit, present
behind a plywood shear wall or metallic wall
covering, or if moisture is present in the
environment or scanned surface.
WARNING
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.
Always turn off the power when working near
electrical wires.
1. INSTALLING THE BATTERY
NOTE: DO NOT LOOSEN OR REMOVE
SCREW ON THE BACK OF THE UNIT.
Squeeze sides of
clip to help release
®
clip end.
Slide a new 9-volt
®
battery into
compartment,
LED
terminal side first,
matching (+) and
(–) terminals from
®
battery to case.
®
Replace the clip.
2. OPERATING TIPS
For optimum scanning results:
• Hold the tool straight up and down, parallel to
the studs, and do not rotate the tool.
• Keep tool flat against the wall and do not rock,
tilt, or press hard when slowly sliding across the
surface being scanned.
• Avoid placing your other hand, or any other part
of your body, on the surface being scanned.
• Depending 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.
• To avoid surprises, remember that studs or
joists are normally spaced 16 in. (41 cm) or 24 in.
(61 cm) apart and are 1
Anything closer together or a different
width may not be a stud, joist,
or firebreak.
1
⁄2 in. (38 mm) in width.
If you’re receiving erratic scanning results, it
may be a result of humidity, moisture within the
wall cavity or drywall, or recently applied paint
or wallpaper that hasn’t fully dried. While the
moisture may not always be visible, it will interfere
with the tool’s sensors. Please allow a few days for
the wall to dry out.
WARNING
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 and 24 in. (41 and 61 cm) stud
spacing practices.
Always turn off the power when working near
electrical wires.
Do not rely exclusively on
the detector to locate items
WORKING WITH DIFFERENT MATERIALS
StudSensor™ Pro SL-AC is for use on dry interior
walls only.
StudSensor™ Pro SL-AC can scan effectively
through most sheet materials, including:
• Bare wood flooring (in DEEPSCAN® mode)
• Linoleum on wood base
• Gypsum drywall over plywood sheathing
• Wallpapered walls (if dry)
• Textured ceilings if uniform thickness (place a
thin piece of cardboard on ceiling and scan over
it to avoid damage to texturing)
StudSensor™ Pro SL-AC is not designed to scan
materials such as:
• Ceramic floor tile
• Carpeting and padding
• Wallpaper with metallic fibers
• Freshly painted walls that are still damp
take one week or longer to dry after
(may
application)
• Lath and plaster walls
• Foil covered insulation board
• Glass or any other dense material
Note: Sensing depth and accuracy can vary due
to moisture, content of materials, wall texture,
and paint.

FCC Part 15 Class B Registration Warning
This device complies with Part 15 of FCC Rules. Operations subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Probable Causes
• Scan began on dense part of wall or
over a stud.
• Unit not flat against wall.
• Unit tilted or lifted during scan.
(All these factors affect proper
calibration.)
• Scanning surface is too dense or too
wet for unit to operate.
• Wall is particularly thick or dense.
• Unit may not be flat against
the wall.
• If it is in the DEEPSCAN
(DEEPSCAN

®
• You may have calibrated over a
stud. (The error condition is disabled
in DEEPSCAN
twice as sensitive as STUD SCAN.)
• You may be holding the unit like a
TV remote, aiming it at the wall.
• Electrical wiring and metal or plastic
pipes may be near or touching back
surface of wall.
• Wires may be shielded behind
metallic wall coverings, plywood
shearwall, or other dense material,
or in conduit.
• The wires may not be live.
• Wires deeper than 2 in. (51 mm)
from surface may not be detected.
• Voltage detection can spread on
drywall as much as 12 in. (30 cm)
from each side of an actual
electrical wire.

• Turn unit off, move over a few inches (5–8 cm),
press Power button, and start again.
• On rough surfaces, place a thin piece of cardboard on
wall, scanning over it to help slide unit more smoothly.
• Keep hand at least 6 in. (15 cm) from unit while you
calibrate and scan. Hold unit with thumb and index
finger no higher than handgrips. Be careful not to
move your fingers after calibration.
• Always hold unit parallel to the stud and move it
perpendicular to the stud you’re trying to locate.
• If you are using unit on a recently taped, painted,
or wallpapered wall, allow time to dry and try again.
• Switch to DEEPSCAN
• Interpret the highest LED obtained as the stud edge.
• Hold unit so two Velcro® strips on the back make
contact with wall.
• Recalibrate unit in a different place and re-scan area.
• Move unit over a few inches (5–8 cm) and recalibrate.
• Hold unit so two Velcro
contact with wall.
• Check for other studs equally spaced to either side
12, 16, or 24 in. (30, 41, or 61 cm) apart or for the
same stud at several places directly above or below
the first scan area.
• Use extra caution if the area has plywood, thick wood
backing behind drywall, or thicker-than-normal walls.
• If a switch controls an outlet, make sure it is ON for
detection, but turned off when working near electrical
wires.
Always turn off power when cutting, nailing, or drilling
near electrical wires.
• To narrow detection, turn unit off and on again at the
edge of where wire was detected and scan again.
Always turn off power when cutting, nailing, or drilling
near electrical wires.
