thought to be
Low confidence meter

PROBABLE CAUSE
• No power to unit
• Unit is in process of
mapping scanned area
• Too narrow an area
mapped
• Difficulty in scanning
below special wall
condition
• Metal items too deep
• Metal items such as
jewelry are too close to
sensor area
• Double or triple studs are
common around doors
and windows
• Static charge may be
present on the wall
surface
• Wires are shielded by
metal conduit
• Wires are deeper than
76 mm (3")
• Wires are not live
• Cannot scan below
special wall condition
• Scanning in a non-straight
line
• Scanning too fast
• Difficulty scanning below
special wall condition
• Scanning too fast
• Hand-held radar scanner
lifted off wall surface
• Wall is thick or dense
• Software lockup
SOLUTION
• Make sure 10.8 V battery pack is fully charged
• Fully seat the 10.8 V battery pack in the handle
• Refer to Scanning Process section
• Re-map larger area
• Scan slowly
• Scan in a straight line
• Refer to Detection Through Special Surface
Conditions section
• Scan in both the horizontal and vertical
directions
• Scan in both horizontal and vertical straight
lines. Metal sensitivity is increased when the
metal object is parallel to the sensor.
• Remove jewelry & re-scan
• Detect outer edge instead
• Scan a smaller area
• Turn off the electrical circuit and identify metal
wire instead
• Place your free hand on the wall to drain static
• Review identified metal in scanning window to
determine metal conduit
• Plug an item into a wall outlet to verify live circuit
• Refer to Detection Through Special Surface
Conditions section
• Scan slowly
• Scan in a straight line
• Refer to Detection Through Special Surface
Conditions section
• Scan slowly
• Re-map area and repeat scanning
• Refer to Detection Through Special Surface
Conditions section
• Insert a small object (i.e., paper clip end) into
the reset button. The reset button is located on
the back surface, under the label. There is a
circle on the label indicating the reset location.
