**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 THAT EVERYTHING
DETECTED IS A STUD.

• Always use a new 9V alkaline battery with an extended expiration date of at least 3 years beyond the current date. Match battery direction to the image inside of battery cavity.

• Do not rely exclusively on the tool 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, wiring into walls such as in a basement, and standard stud-spacing practices.

• Always start your scan in Target Control ® (TC ™ ) mode, which scans through standard single-layer drywall up to 3 ⁄4″ (19 mm) deep.

• 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, as a stud would.

• Studs normally run from floor to ceiling, except above and below windows and above doors.

• Readings should always be consistent and repeatable.

• Zircon® stud finders are recommended for interior use only.

• Other objects commonly contained in walls, floors, or ceilings are water pipes (plastic and metal), 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.

• 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 could contain these items. Use extreme caution under these circumstances or whenever live AC wiring is present.

• Studs are normally spaced 16″ or 24″ (40 cm or 60 cm) apart on the center, are normally 1 1 ⁄2″ (38 mm) wide, and may be separated by firestops. Anything closer together, or of different width, may not be a stud.

IMPORTANT: Trust but Verify is a technique that can help indicate “safe- to-drill” zones to minimize hitting existing metals on a stud, such as nails, screws, and protector plates. When the Crosshairs show in TC ™ mode, run the tool vertically up and down the stud. The stud indicators (Crosshairs, Edge Indicators, Target Indicator Bars, Target Spotlight, and SpotLite ® Pointer) will all turn off over screws and other metal, then turn on again when the stud is free from metal. The “safe-to-drill” zones are typically between adjacent drywall screws, nails, or protector plates, assuming the builder properly installed metal protector plates on the stud, and over plumbing and electrical. If stud indicators do not disappear when running vertically up and down the object in TC ™ mode, the absence of drywall screws, nails, and protector plates indicate this could be a non-metallic object such as plastic plumbing or PEX tubing, and should not be mistaken for a stud.

TROUBLESHOOTING & CONSTRUCTION TIPS

Tool detects objects than studs in StudScan mode or finds more objects
that look like 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 16″ or 24″ (40 cm or 60 cm) and check for the same stud at spots directly above or below the first scan area.
•Standard studs measure approximately 11/2″ (38 mm) between edges. Anything smaller or larger is likely not a stud (unless near a door or window).
Studs are continuously detected near windows and doors.| Multiple studs are in use.| Double and triple studs are sometimes used around doors and windows. Headers are used above them. Detect the outer edges so you know where to begin.
Electrical wires were suspected but none were detected.| Wires deeper than 2″ (50 mm) from the surface might
not be detected.| If there is an outlet switch, turn it to the ON position while scanning, but turn it 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 may not be live.| Plug a lamp into the outlet and turn it on to test whether the wires are live.
LCD screen flashes continuously when trying to find a stud.| The tool is experiencing oversaturation of exposure to the metal.| Switch to TCT” or StudScan mode to lessen sensitivity to metal.
NOTE: The tool may not beep over studs 1″ (25 mm) or deeper when doing this.
Low Battery Indicator on.| Low battery.| Install a new 9V alkaline battery with an extended expiration date.
The low Battery Indicator flashes and the tool does not operate.| Dead battery.

Featuring Revolutionary Target Control ® (TC ™ )
 Technology TC ™ technology is tuned to find wood studs while filtering out (rejecting) metallic or low signal false positive objects such as plumbing, conduit, straps, brackets, or plastic water pipes. With TC ™ mode, users can utilize Trust but Verify technique to help identify “safe-to-drill” zones between adjacent drywall screws, nails, and protector plates.
Three scanning modes:

• Target Control ® (TC ™ ) locates the center, edges, and direction of wood studs (while ignoring metal) up to 3 ⁄4″ (19 mm) deep. LCD will be backlit with a pale blue light. In TC ™ mode, the LoLevel ™ Indicator indicates low (weak) signal objects, such as plastic water pipes, plastic sewer drains, or studs deeper than 3 ⁄4″ (19 mm). When compared to stud signals, the LoLevel ™ Indicator may help differentiate studs from false positives.
• StudScan locates the center, edges, and direction of both wood and metal studs up to 3 ⁄4″ (19 mm) deep. LCD will not be backlit in this mode. In StudScan mode the Signal Strength Indicator uses the same icon as the LoLevel ™ Indicator. When TC ™ is off, a strong signal is indicated by full signal strength bars.
• DeepScan ® locates the center, edges, and direction of studs (wood and metal) up to 1 1 ⁄ 2″ (38 mm) deep.

LCD will be backlit with a green light.
NOTE: TC ™ and StudScan use the same switch setting but function differently. StudScan detects both wood and metal studs during scanning, while TC ™ detects only wood studs and ignores metal. You can distinguish between the two modes by the pale blue backlight on the LCD in TC ™ mode. StudScan is not backlit. MetalliWarning ™ Indicator will display when metal is detected or dangerously close in TC ™, StudScan, and DeepScan ®  modes.

WIREWARNING ® DETECTION

The Zircon ® WireWarning ® Detection continuously detects and alerts for live, unshielded AC (alternating current) wires in any mode. When live AC voltage is detected, a warning indicator appears and the screen starts flashing red until the tool is moved sufficiently away from the live wire. When calibration begins over an AC wire in any mode, the AC icon will flash. Use extreme caution under these circumstances or whenever live AC wiring is present.

WARNING
The tool may not detect AC activity if wires are more than 2″ (50 mm) behind the scanned surface, in concrete, encased in conduit, behind a plywood shear wall or metallic wall covering, or if moisture is present in the environment or scanned surface.
INSTALL 9-VOLT BATTERY
Always use a new 9V alkaline battery with an extended expiration date of at least 3 years beyond the current date.
Match battery direction to image inside battery cavity.
WARNING
Do not rely exclusively on tools 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.

SELECT MODE / POWER UP

Move Mode Selector Switch to the desired mode: TC ™ / StudScan or DeepScan ®.
To activate the tool, press and hold Power Button. The device shuts off 1–2 seconds after Power Button is released.

FIND A CLEAN WOOD STUD IN TARGET CONTROL ® (TC ™ ) MODE

TC ™ is designed to detect wood studs during scanning.
For best results, hold the tool as shown and move slowly when scanning. Do not touch the surface during calibration or scan.

1. Set mode to TC ™ / StudScan switch.

2. Hold the tool flat against the wall, then press and hold Power Button. (Figure A) The device will calibrate in 1–2 seconds. Proper calibration is confirmed by a short beep, a flicker of SpotLite ® Pointer, and a flash of icons. If a calibration error occurs, all icons will flash continuously. NOTE: Screen will have a pale blue backlight in TC ™ mode. DO NOT MOVE THE TOOL DURING CALIBRATION.

3. While holding down Power Button, slide the tool slowly along the wall. When the tool finds the edge of a stud, Edge Indicator shows. (Figure B)

4. Continue sliding. When the tool finds the center of a stud, Crosshairs show and SpotLite ® illuminates. Mark spots where the stud was found. (Figure C)

5. The tool automatically recalibrates when in use. If the two ACT™ arrows appear on LCD, the tool was calibrated over a stud, then moved away. This is ACT™ (Auto Correcting Technology) in action.
   NOTE: LoLevel ™ Indicator will display rapidly cascading bars when the device senses a sustained weak signal, indicating a false positive object may be present.

6. Use the Trust but Verify technique for finding drywall screws or nails up and down studs to confirm that you have located a wood stud. Other objects, such as plastic plumbing pipes, do not contain nails or drywall screws. (See important note under BEFORE YOU BEGIN for more information on this procedure.)

FIND A STUD IN STUDSCAN MODE (TC ™  OFF)

1. Set mode to TC ™ / StudScan switch.

2. Hold the tool flat against the wall, press the Power Button, release it, then press it again, holding it down the second time. The device will calibrate in 1–2 seconds. A short beep confirms that calibration is complete. If a calibration error occurs, all icons will flash continuously.
   NOTE: The tool is in StudScan mode (TC ™ off) when the LCD backlight is off. When TC ™ mode is off, metal objects may be indicated as a stud and Signal Strength Indicator will have steady strength bars. DO NOT MOVE THE TOOL DURING CALIBRATION.

3. While holding down Power Button, slide the tool slowly along the wall. When the tool finds the edge of a stud, Edge Indicator shows.

4. Continue sliding. When the tool finds the center of a stud, Crosshairs turn on, SpotLite ® illuminates, and a beep sounds. (Figure D) Mark spots where the stud was found.

5. The tool automatically recalibrates when in use. If the two ACT ™ arrows appear on the LCD, tool was calibrated too close to a stud, then moved away. This is ACT ™ (Auto Correcting Technology) in action. (Figure E) To return to TC ™ mode, release and press the Power Button again. When the display is backlit pale blue, you are back in TC ™ mode.

SCAN IN DEEPSCAN ® MODE
DeepScan ® mode is used to scan for deeper studs or for use with thicker walls. It can detect studs up to

1. 1 ⁄2″ (38 mm) deep. 1. Set mode to DeepScan ®.
2. Repeat steps 2–4 under the STUDS CAN MODE section.
   NOTE: When scanning on thicker surfaces, the device may not find edges on surfaces thicker than 3 ⁄4″ (19 mm).

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, 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.

WORKING WITH DIFFERENT MATERIALS

Wallpaper Tool 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 It may take a week or longer to dry after application.
Lath and plaster This tool is not designed to scan over lath and plaster.
Highly 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.
W ood flooring, subflooring, or gypsum drywall over plywood sheathing Use DeepScan ® mode and move the tool slowly. This tool cannot scan for wood studs and joists through carpet 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, tools 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 Studs are normally spaced 16″ or 24″ (40 cm or 60 cm) apart in the center and are 1 1⁄2″ (38 mm) wide.
Anything closer together, or of different width, may not be a stud.
