Cautions on Operating
You should always use caution when
nailing, cutting or drilling in walls,
ceilings and floors that may contain
wiring or pipes near to the surface.
Shielded, dead or non-powered wiring
will not be detected as live wires.
Always remember that studs or joists are
normally spaced 41 cm (16") or 61 cm
(24") apart and are 38 mm (1-1/2") in
width. To avoid surprises, be aware that
anything closer together or of a different
width may be an additional stud, or joist
fire break.
When working near AC electrical wires,
always turn off the power.
Operating Tips
IMPORTANT SAFETY NOTICE
To ensure proper detection of live wires,
ALWAYS hold the IntelliSensor™ Pro in
the handle area only. Grasp between
fingers and thumb while maintaining
contact with your palm.
Conventional Construction
Doors and windows are commonly
constructed with additional studs and
headers for added stability. The
IntelliSensor™ Pro detects the edge of
these double studs and solid headers
and emits and holds an audio signal as it
crosses over them.
