into walls, such as in a basement, and standard 16" (40 cm) and 24"
(60 cm) stud spacing practices.
WARNING: You should always use caution when nailing,
cutting or drilling in ceilings, walls and floors that may contain
wiring or pipes near the surface. Shielded, dead or non-
powered wires will not be detected as live wires. Remember that
studs or joists are normally spaced 16" (40 cm) or 24" (60 cm) apart
and are usually 1-1/2" (38 mm) in width. Beware of anything closer
together or a different width. Always turn the power off when working
near electrical wires. Also, shut off gas and water supplies.
WARNING: To reduce the risk of injury and electric shock,
always turn off power when working near electrical wires. Metal
shielded wires or those in metal conduit will not be detected. Use
extreme caution in these circumstances or whenever live AC wiring
is present. Test the functionality of the AC, detect on a well known
power supply prior to measurement.
WARNING: Live wires deeper than 2" (50.8 mm) from the
surface, in plastic conduit, behind plywood sheer wall or
metallic wall coverings, cables operating at DC current or wires
used in telecommunications and computer systems may not be
detected. Wires that are not live may be detected as metal objects.
WARNING: Do not use the tool to detect AC voltage in
un-insulated, exposed or free wires. Do not use as a substitute
for a volt meter.
WARNING: Detection values can be impaired through certain
ambient conditions. These include the proximity of other equipment
that produce strong magnetic or electromagnetic fields, moisture,
metallic building materials, foil laminated insulation materials or
conductive wall paper or tiles. Use of transmitting systems such as
WLAN, UMTS, radar, transmitting masts or microwaves can influence
the measurements.
CAUTION: Do not use on humans or animals. This is not for
human or animal use and can cause injury if used.
CAUTION: When not in use, place hand-held radar scanner
on its side on a stable surface where it will not cause a tripping
or falling hazard. Some tools with large battery packs will stand
upright on the battery pack but may be easily knocked over.

WALLPAPER
The hand-held radar scanner will function normally on walls covered
with wallpaper or fabric, unless the materials are metallic foil, contain
metallic fibers or are still wet after application.
