2. SELECTING THE MODE
Battery
Move selector switch to the desired mode: STUD SCAN for finding wood
(back of tool)
or metal studs; METAL SCAN for locating metal; or AC SCAN for locating
hot AC wiring.
Move selector switch to the OFF position when not in use to prevent the
tool from accidentally powering on and wearing down the battery.
7. SCANNING IN METAL MODE (continued)
1. (Figure A) Press the tool flat against the wall and slowly slide the tool across the surface.
Mark the spot where the display bars peak. If it is a strong target, the SpotLite Pointing
®
System will also shine a beam of light and a steady beep will sound. Continue in same
direction until display bars reduce. Reverse direction and mark the spot where the display
bars peak from the reversed direction. The midpoint of the two marks is the location of the
center of the metal object.
If the tool indicates metal over a large area, you can refine the scanning area to more
accurately locate the metal target.
2. (Figure B) To further pinpoint the location of the metal target, scan the area again.
Release the handle and then turn the tool back on, this time starting on the wall over
one of the previous marks. This will reset the tool to a lower sensitivity and make the
scan more precise.
3. (Figure C) Scan in both directions as in Step 1. The area indicated should
become smaller so you can more precisely identify the metal location.
This procedure can be repeated to narrow the field even further.
Note: Small targets or targets deep within the surface may only illuminate some
of the bars and not the center line or audio tone. In this case, use the highest
indication to determine the metal position.
8. SCANNING IN AC MODE
As with METAL SCAN Mode, AC SCAN Mode has interactive calibration and works in the
same manner.
1. (Figure A) Press the tool flat against the wall and slowly slide the tool across the surface.
Mark the point where you get the highest AC indication (the most bars on the screen). If it
is a strong target, the SpotLite ® Pointing System will also shine a beam of light and a steady
beep will sound. Continue in same direction until display bars reduce. Reverse direction and
mark the spot where the display bars peak from the reversed direction. The midpoint of the
two marks is the location of the center of the live AC wiring.
If the tool indicates live electricity over a large area, you can refine the scanning area to
more accurately locate the live AC wiring by following steps 2 and 3 below.
2. (Figure B) To further pinpoint the location of the live AC wiring, scan the area again.
Release the handle and then turn the tool back on, this time starting on the wall over
one of the previous marks. This will reset the tool to a lower sensitivity and narrow the scan
area.
3. (Figure C) Scan in both directions as in Step 1. The area indicated should become
smaller so you can more precisely identify the location of live AC wires. This procedure
can be repeated to narrow the field even further.
Note: AC SCAN mode will only detect live (energized) AC wiring.
3. FINDING A STUD

FCC Part 15 Class B Registration Warning
This device complies with Part 15 of FCC Rules. Operation is 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.
4. OPERATING TIPS
For optimum scanning results, it is important to properly hold MultiScanner
slowly when scanning. The following tips will ensure accurate scanning results:
• Grasp the handle with your thumb on one side and your fingers on
the other side. Make sure your fingertips are resting on or above the
running board and not touching the surface being scanned or the
scanning head of the tool.
• 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 or tilt the tool when
slowly sliding across the surface being scanned.
• Make sure your other hand (or any other part of your body) is not
touching the surface being scanned. This will interfere with the
tool's performance.
5. CALIBRATING THE TOOL
MultiScanner 740 constantly monitors the subsurface environment 10 times per second
®
and automatically recalibrates, when needed, to successfully find the center of studs in
one step!
• Place MultiScanner ® 740 against the wall and press the handle until it lays flat against
the wall. Pressing the tool to lay flat against the wall will automatically power on the tool
via the internal On/Off switch.
• Once powered on, tool will automatically perform all calibrations. The LCD will display all
icons until calibration is complete. Upon completion of calibration, the SpotLite
will momentarily activate and the tool will begin continuous measurements. Continue to
Pointing
press the tool flat against the wall and begin scanning.
Note: It is important to wait for calibration to complete (1–2 seconds) before moving
the tool.
• ACT ™ (Auto Correcting Technology)—During scanning, the tool will automatically recalibrate
itself when needed. This recalibration is
usually transparent and no indication is
made. If the tool is initially calibrated
near a stud and then moved away
(it will detect the density of the wall
decreasing), an arrow icon will be
illuminated, indicating the direction of
the missed stud.

6. WORKING WITH DIFFERENT MATERIALS
® 740 and move Wallpaper: The MultiScanner ® 740 functions normally on walls covered with wallpaper or fabric,
unless the materials are metallic foil, contain metallic fibers, or are still wet after application.
Wallpaper may need to dry for several weeks after application.
Lath & plaster: Due to irregularities in plaster thickness, it is difficult for the MultiScanner
to locate studs in STUD SCAN mode. Change to METAL SCAN mode to locate nail heads holding
laths to stud. If plaster has metal mesh reinforcement, MultiScanner
through that material.
Textured walls or acoustic ceilings: When scanning a ceiling or wall with an uneven surface,
place thin cardboard on the surface to be scanned and scan over the cardboard. Calibrate with
cardboard in place.
Wood flooring, subflooring, or gypsum drywall over plywood sheathing: Use STUD SCAN mode
and move the tool slowly. The signal strength indicator may only display 1 or 2 bars when the tool
locates a stud through thick surfaces.
MultiScanner ® 740 cannot scan for wood studs and joists through concrete or carpeting and pad. In
problematic situations, try using METAL SCAN to locate nails or drywall screws that line up vertically
where a stud is positioned.
Note: Sensing depth and accuracy can vary due to moisture, content of materials, wall texture,
and paint. Indoor use only.
Do not rely exclusively on the detector to locate items behind the scanned

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.
® and buzzer
7. SCANNING IN METAL MODE
Note: When scanning for metal studs, use STUD SCAN mode to quickly locate the center and edges of
wood or metal studs. Use METAL SCAN mode only to determine if studs are wood or metal. In METAL
SCAN mode, only metal drywall screws will be found in wood studs, while metal will be indicated
everywhere on a metal stud.
METAL SCAN mode has interactive calibration to adjust its sensitivity to metal which can be used
to find the precise location of metal objects in walls, floors, and ceilings. Maximum sensitivity is
ideal for quickly finding the approximate location of metal. However, the user can reduce sensitivity
by turning on the tool closer to metal. The reason for reducing sensitivity is because with less
sensitivity, the area where metal is indicated will be smaller. But in both cases, the metal target is
in the center of the area where the tool indicates metal is present.
