Troubleshooting
SITUATION
PROBABLE CAUSE
SOLUTION
Unit does not turn on
• No power to unit
• Make sure 10.8 V battery pack is fully charged
• Fully seat the 10.8 V battery pack in the handle
Unit does not display objects;
says Pre-Scan Data Mapping
• Unit is in process of
mapping scanned area
• Refer to
Scanning Process
section
No materials detected or
difficult in detecting objects
• Too narrow an area
mapped
• Difficulty in scanning
below special wall
condition
• 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
Difficulty in detection of metal
• Metal items too deep
• Scan in both horizontal and vertical straight
lines. Metal sensitivity is increased when the
metal object is parallel to the sensor.
Seemingly false metal
detection
• Metal items such as
jewelry are too close to
sensor area
• Remove jewelry & re-scan
Difficulty in scanning near
door or windows
• Double or triple studs are
common around doors
and windows
• Detect outer edge instead
Area of voltage detected is
larger than anticipated
• Static charge may be
present on the wall
surface
• Scan a smaller area
• Turn off the electrical circuit and identify metal
wire instead
• Place your free hand on the wall to drain static
Electrical voltage not
detected in area where it was
thought to be
• Wires are shielded by
metal conduit
• Wires are deeper than
76 mm (3")
• Wires are not live
• Cannot scan below
special wall condition
• 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
Low confidence meter
reading
• Scanning in a non-straight
line
• Scanning too fast
• Difficulty scanning below
special wall condition
• Scan slowly
• Scan in a straight line
• Refer to
Detection Through Special Surface
Conditions
section
Received error message:
Too fast
• Scanning too fast
• Scan slowly
Received error message:
Lost surface contact
• Hand-held radar scanner
lifted off wall surface
• Re-map area and repeat scanning
Cannot get a center line to
appear
• Wall is thick or dense
• Refer to
Detection Through Special Surface
Conditions
section
Screen freezes or won't
turn on
• Software lockup
• 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.
