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.

Low Battery Indicator: The Low Battery Indicator icon displays

when the battery level is getting low. While the tool will still operate,

the battery will need to be replaced soon. When the battery icon begins

to flash and is the only icon displayed on the screen, the battery level is too low and not

sufficient to power the tool for proper operation. Please replace the 9-volt battery with

a brand new battery immediately.

2. OPERATING TIPS

For optimum scanning results, it is important to properly hold

the MultiScanner

350 and move slowly when scanning.

The following tips will provide more 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

the handle 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, 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. 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.

• 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 or 24 in. (41 or 61 cm) apart and are 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 power when working near electrical wires.

SCANNING DIFFERENT SURFACES

Wallpaper: MultiScanner

350 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.

Lath & plaster: Due to irregularities in plaster thickness,

it is difficult for MultiScanner

350 to locate studs in Stud

modes. Change to Metal Scan mode to locate the nail heads

holding wood lath to the studs. If the plaster has metal mesh

reinforcement, MultiScanner

350 may be unable to detect

through that material.

Extremely 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 in DeepScan

mode. If irregular scanning results are

received, switch to Metal Scan mode to locate nails or drywall

screws that line up vertically where a stud or joist is positioned.

Wood flooring, subflooring, or gypsum drywall over

plywood sheathing: Use DeepScan

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

350 cannot scan for wood studs and joists

through concrete or carpet and padding. In problematic

situations, try using Metal Scan to locate nails or screws that may line up vertically

where a stud or joist is positioned.

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.

3. SELECTING THE MODE

Move selector switch to the desired mode: StudScan for finding wood or metal

studs; DeepScan

for scanning walls over

⁄4 in. (19 mm) thick; or Metal Scan

for locating metal.

Unit will remain off if Power button is not pressed.

4. TURNING ON/CALIBRATING THE TOOL

MultiScanner

350 can be calibrated anywhere on the wall. It provisionally 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

350 against the wall before pressing the Power button in

StudScan or DeepScan

mode.

• 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

Pointer and buzzer will momentarily activate and the tool will begin

continuous measurements. Continue to press Power button down and keep 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 scanner.

ACT

™

(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 or over a stud and then moved

away. The arrow indicates the direction

of the missed stud.

Note: If any bars display on the screen, metal is present. 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.

5. FINDING A STUD

Always scan for studs with the scanner placed flat against the wall.

Move the mode switch to StudScan, 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.

Slowly slide tool across surface. EDGE indication

will illuminate, indicating location of the stud edge.

Continue sliding tool. When the center of a stud

is located, the three bars on the Signal Strength Indicator,

the middle segments of the Target Indication bars,

CENTER indication, and SpotLite

Pointer will all

illuminate and the buzzer will sound.

In cases of deeper studs (thicker walls), when the

center of the stud is located only two bars will show

on the Signal Strength Indicator and only the SpotLite

Pointer and middle segments of the Target Indication

bars will illuminate. If you still cannot locate a stud,

try DeepScan

mode.

6. WIREWARNING

DETECTION

Zircon's WireWarning

detection feature works continuously in StudScan, DeepScan

and Metal Scan modes. When live AC voltage is detected, the AC detection warning

indicator will appear in the display. If scanning begins over a live AC wire, the AC

indicator will flash continuously. Use extreme caution under these circumstances or

whenever live AC wiring is present.

Electrical field locators may not detect live AC wires if wires

are more than 2 in. (51 mm) from the scanned surface, in

concrete, 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 StudScan mode (or DeepScan

mode on thicker

walls) to quickly locate the center and edges. Use Metal Scan to determine if the

previous reading in StudScan 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.

Metal Scan 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.

Maximum sensitivity is ideal for quickly finding the approximate location

of metal. However, sensitivity can be reduced by calibrating the tool closer to metal.

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.

1. Move mode switch to Metal Scan mode. For 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 Target Indication bars on the screen). If it is a strong target,

the SpotLite

Pointer 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.

WARNING

MultiScanner

L350 OneStep

Multifunction Wall Scanner

Detects other objects besides studs

in StudScan mode.

Finds more targets than there

should be.

• Electrical wiring and metal/plastic pipes may be

near or touching back surface of wall.

• Scan the area in Metal Scan to determine if metal is present.

• Check for other studs equally spaced to either side 12, 16, or 24 in. (31, 41, or 61 cm) apart or for the same stud

at several places directly above or below the first scan area.

• A stud reading would measure approximately 1

⁄2 in. (38 mm) apart from each edge; anything larger or smaller is

most likely not a stud if not near a door or window.
