109F Manual (B/E/F)
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 the surface. Shielded, dead or non-
powered wiring will not be detected
as live wires. Always remember that studs
or joists are normally spaced 16 inches or
24 inches apart and are 1-1/2 inches in
width. To avoid surprises, be aware that
anything closer together or of a different
width may be an additional stud, joist or fire
break.
When working near AC electrical
wires, always turn off the power.

Conventional Construction
Doors and windows are commonly
constructed with additional studs and
headers for added stability. The
IntelliSensorTM Pro detects the edge of
these double studs and solid headers and
emits and holds an audio signal as it crosses
over them.
