FCC Part 15 Class B Registration Warning
This equipment has been tested and found to comply with the limits for a Class B digital device, pur- suant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no guar- antee that
interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be deter- mined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
(1)Reorient or relocate the receiving antenna.
(2)Increase the separation between the equipment and receiver.
(3)Connect the equipment into an outlet on a circuit, different from that which the receiver is connected (if applicable).
3 | Replace the clip. |
| Battery will last |
approximately two years under normal conditions.
CALIBRATION AND SCANNING IN STUD SCAN OR DEEPSCAN® MODES
Note: Unit calibrates on each use.
Use Stud Scan Mode for depths to about 3⁄4 in. (19 mm) and DeepScan for depths up to
11⁄2 in. (38 mm) or double layers.
Note: Keep unit flat against wall. Do not lift or tilt unit during calibration or scanning.
4 | Slide the Mode Selector |
| switch to the desired |
scanning mode. The mode can | |
be selected with the unit on | |
or off. | |
5 | With StudSensor Pro |
| turned off, position the unit |
flat against the wall. | |
6 | Without moving unit, squeeze |
| and hold On/Off button. |
TruCal® LED should be lit. | |
7 | Continue to hold |
| in the On/Off |
button then slowly slide | |
unit horizontally across | |
the wall, right or left. | |
8 | As you begin to approach a stud, the red LEDs |
| will light successively, from bottom to top. |
10 Continue scanning beyond marked
spot until green LED goes out. Slide unit in reverse direction to locate other edge of stud.
11 Mark this second spot. Middle of stud
is centered between the two marks.
CONTINUOUS AC VOLTAGE DETECTION (WireWarning™)
12 The StudSensor Pro
AC in a hot electrical wire. The voltage detection feature works continuously in both Stud Scan and DeepScan modes. When sensing voltage, the small AC light comes on.
Caution: The StudSensor Pro
OPERATING CAUTIONS
13 | 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 in. (406 mm) or 24 in. (610 mm) apart and are 11⁄2 in. (38 mm) in width. Anything closer together or a different width may not be a stud, joist, or firebreak. Always turn off the power when working near electrical wires.
(4)Consult the dealer or an experienced radio/TV technician for help.
