Use And Care Manual

1. INSTALLING THE BATTERY
Press battery door release in with your finger or a coin and lift up to remove
door. Connect new 9-volt battery to cable. Place into the compartment
and press into place. Replace battery door and snap shut.
2. OPERATING TIPS
For optimum scanning results, it is important to properly hold the
MultiScanner
®
i520 and move slowly when scanning. The following
tips will provide more accurate scanning results:
s 'RASP 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.
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. This will interfere
with the tool’s performance.
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.
WORKING WITH DIFFERENT MATERIALS
Wallpaper: MultiScanner
®
i520 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.
Freshly painted walls: May take one week or longer to
dry after application. If it is difficult to locate a stud in

Note: Sensing depth and accuracy can vary due to moisture, content of materials, wall
texture, and paint.
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 and 24 in. (41 and 61 cm) stud
spacing practices.

(Auto Correcting Technology)
During scanning, the tool will
automatically recalibrate itself when
needed. This recalibration is transparent
and no indication is made. If an arrow
icon illuminates, the tool calibrated near

The arrow indicates the direction of the
missed stud.

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.
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 power when working near electrical wires.
7. SCANNING IN METAL MODE
Note: When scanning for studs, use STUD SCAN mode (or Stud DEEPSCAN
®
mode on
thicker walls) to quickly locate the center and edges. Use METAL SCAN to determine
if the previous reading in STUD SCAN was a wood stud, metal stud, or pipe. In METAL
SCAN, only metal drywall screws will be found in wood studs, while metal will be
indicated everywhere on a metal stud or pipe.
-%4!, 3#!. HAS INTERACTIVE CALIBRATION TO ADJUST TO ITS SENSITIVITY TO METAL WHICH
can be used to find the precise location of metal objects in walls, floors, and ceilings.
-AXIMUM SENSITIVITY IS IDEAL FOR QUICKLY FINDING THE APPROXIMATE LOCATION

With reduced 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.
 -OVE MODE SWITCH TO -%4!, 3#!. MODE &OR MAXIMUM METAL SENSITIVITY TURN THE
tool on in the air by pressing and holding the Power button. This will ensure that it
calibrates away from any metal objects.
(The tool can only be calibrated
off the wall in METAL SCAN mode.)
2. (Figure A) While holding the Power button, press the tool flat against the
wall and slowly slide the scanner across the surface. Mark the point where you
get the highest metal indication (the most Middle bars on the screen). If it is a
STRONG TARGET THE 3POT,ITE
®
Pointing System will also shine a beam of light and a
steady beep will sound. Continue in the 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 unit indicates metal over a large area, you can refine the scanning area to
more accurately locate the metal target by following steps 3 and 4 below.
3. (Figure B) To further pinpoint the location of the metal target, scan the area again.
Release the Power button and then turn the unit 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.
4. (Figure C) To continue to reduce sensitivity and further refine the scanning area,
repeat step 3. This procedure can be repeated multiple times to narrow the field
even further.
