WireWarning
Detection
automatically detects and
alerts for live, unshielded AC (alternating current)
wires in both modes. When AC voltage is detected,
the WireWarning Detection Indicator illuminates.
INSTALL 9-VOLT BATTERY
Always use a new alkaline
battery
with an extended expiration date at
least 3 years beyond current date.
Match battery direction to image
inside of battery cavity.
WARNING
Do not rely exclusively on the
scanner to locate items behind a
surface. Use other information to help locate
items before penetrating the surface, including
construction plans, visible points of entry of pipes
and wiring into walls such as in a basement,
and standard stud-spacing practices.
OVER-THE-STUD WARNING
If scanning begins directly over a stud, the tool will emit a
continual beep and the lights will flash.
If this happens, restart the scan in a different location.
WIREWARNING
DETECTION
The Zircon
®
WireWarning Detection
feature works continuously in
both modes. When live,
unshielded AC voltage is detected,

and padding.
NOTE: Sensing depth and accuracy can vary
depending on scanning environment conditions
such as mineral content, moisture, texture and
consistency of the wall materials.
Electrical wiring and pipes
Depending on the proximity
of electrical wiring or pipes to the wall surface, the tool
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.
Studs and joists
are normally spaced 16 or 24" apart
(40 or 60 cm), and are 1

BEFORE YOU BEGIN
ZIRCON

STUD FINDERS WORK BY SENSING DENSITY CHANGES BEHIND THE WALL. OTHER OBJECTS CAN BE DETECTED
ESPECIALLY IF THEY ARE VERY CLOSE TO THE WALL.
DO NOT ASSUME EVERYTHING DETECTED IS A STUD.
- Always use a new alkaline battery with an extended expiration date at least 3 years beyond current date. Match battery
direction to image inside of battery cavity.
- Do not rely exclusively on the scanner to locate items behind a surface. Use other information to help locate such items
before penetrating the surface, including construction plans, visible points of entry of pipes and wiring into walls such as
in a basement, and standard stud-spacing practices.
- Always start your scan in StudScan Mode which scans through surfaces up to
3
⁄
4
" (19 mm) deep. Scanning in
DeepScan
®
Mode may detect an object further behind the wall that may or may not be a stud.
- Always scan for studs at several different heights on the wall and mark the location of every target indicated by the
stud finder. This is called “mapping the wall.” Pipes and other objects will likely not give consistent readings from floor to
ceiling, like a stud would.
- Readings should always be consistent and repeatable.
- Zircon stud finders are recommended for interior use only.
- Studs normally run from floor to ceiling, except above and below windows, and above doors.
- Other objects commonly contained in walls, floors, or ceilings are water pipes, gas lines, firestops, and electrical wiring.
- Sensing depth and accuracy can vary depending on scanning environment conditions such as mineral content, moisture,
texture and consistency of the wall materials.
- Always turn off power when working near electrical wires.
- 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.
- Studs and joists are normally spaced 16 or 24" (40 or 60 cm) apart, are normally 1
1
⁄
2
" (38 mm) wide, and may be
separated by firestops. Anything closer together, or of a different width, may not be a stud or joist.

TROUBLESHOOTING & CONSTRUCTION TIPS
SITUATION
LIKELY CAUSE
SOLUTION
All lights turn on at the
same time and the tool
beeps continuously.
Tool not held flat
against wall.
• Hold the tool with thumb on one side and fingers on the other side. Do not touch the
surface being scanned or the scanning head of the tool.
• Move the tool straight up and down, parallel to the studs. Do not rotate the tool.
Tool tilted or lifted
during scan.
• Move Mode Selector Switch to enter DeepScan Mode.
• When scanning an uneven surface, place thin cardboard on the surface to be scanned
and scan over the cardboard in DeepScan Mode.
Scanning surface is too
dense or too wet for tool
to operate.
If tool is used on a recently taped, painted, or wallpapered wall, allow time to dry
and try again.
Unable to detect studs in
StudScan Mode.
Wall is thick or dense.
Switch to DeepScan Mode to locate the stud.
Green READY Light
illuminates but
nothing happens
during scan.
Tool may not be flat
against wall.
Hold tool so that the pads on the back make full contact with the surface.
Calibration may have
occurred over a stud in
DeepScan Mode.
Recalibrate in a different area, then continue the scan.
Can't detect studs in
DeepScan Mode.
Calibration may have been
over a stud.
Move the unit to a different area, then scan again. Also ensure that the tool is held
against the wall as shown in illustrations.
Tool detects objects
other than studs, or finds
more studs than should
be there.
Electrical wiring and metal
or plastic pipes may be near
or touching the back of the
wall surface.
Check for other studs equally spaced to either side at 12, 16 or 24
"
(30, 40, or 60 cm),
or check for the same stud at spots directly above or below the first scan area.
Studs will run straight up and down, from floor to ceiling, while pipes may change
direction. Standard studs measure approximately 1
1
⁄
2
"
(38 mm) between edges.
Anything larger or smaller is likely not a stud (unless near door or window).
Area of voltage detection
is too large.
Voltage detection can
spread on drywall by as
much as 12" (30 cm) on
each side of the wire.
Narrow the scan detection:
1.
Turn tool off.
2.
Turn it on again at the edge of where the
wire was first detected.
3.
Repeat scan.
Electrical wires suspected,
but WireWarning
®
Detection does not alert.
Wires are shielded by a
metal conduit, braided wire
or metallic wall covering.
If there is an outlet switch, turn it to ON position while scanning, but turn OFF when
working near the wires.
Use extra caution if the area has plywood, thick wood
backing behind drywall, or walls that are thicker than normal.
Wires deeper than 2
"
(50 mm) from the surface
might not be detected.
See above.
Wires may not be live.
Plug a lamp into the outlet and turn it on to test whether wires are live.
