FUNCTIONAL DESCRIPTION
PERSONAL SAFETY
WORK AREA SAFETY
SYMBOLOGY
• Avoid dangerous environments
. Do not use in
rain, snow, damp or wet locations.
Do not use in
the presence of explosive atmospheres (gaseous
fumes, dust or
fl
ammable materials) because
sparks may be generated when inserting or remov-
ing battery pack, possibly causing
fi
re.
• Stay alert, watch what you are doing and use
common sense when operating the Sub-Scan-
ner. Do not use while you are tired or under
the infl uence of drugs, alcohol or medication.
A moment of inattention may result in serious
personal injury.
• Do not overreach. Keep proper footing and
balance at all times.
This enables better control
in unexpected situations.
BATTERY USE AND CARE
SERVICE
• Recharge only with the charger specifi ed by
the manufacturer.
A charger that is suitable for
one type of battery pack may create a risk of
fi
re
when used with another battery pack.
• Use power tools only with specifi cally desig-
nated battery packs.
Use of any other battery
packs may create a risk of injury and
fi
re.
• When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another.
Shorting the battery termi-
nals together may cause burns or a
fi
re.
• Under abusive conditions, liquid may be eject-
ed from the battery, avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
ASSEMBLY
WARNING

OPERATION
WARNING
Always remove battery
pack before changing or removing
accessories. Only use accessories specifi -
cally recommended for this tool. Others may
be hazardous.
On/Off
Press the button to turn the tool on and off.
Sleep Mode
The Sub-Scanner is automatically powered off in
about 20 minutes after the last operation. To reset,
press any button. If the display is blank when the
Sub-Scanner is turned ON, charge the battery ac-
cording to the battery/charger manual.
The Sub-Scanner does use battery power in sleep
mode. Be sure to turn OFF the tool to conserve
battery power.
Set-up
1.Turn on the Sub-Scanner (defaults to Metal mode
without sound).
2.Press the MENU button.
3.Use the up and down buttons to scroll
through the menu items (UNITS, SOUND). Use
the Calibrate button to select.
UNITS - Select either English or Metric units.
SOUND - Turn sound On or Off
4.Press the MENU button again to exit.
Selecting Mode
1.Turn on the Sub-Scanner.
2.Metal mode is the default scan setting.
3.To change between Metal and Stud, select the
METAL and STUD buttons.
METAL Mode
In metal mode, the Sub-Scanner will detect both
ferrous (>14 mm Ø) and non-ferrous (>16 mm Ø)
metals in concrete up to a depth of 6". The Sub-
Scanner can not reliably detect metal behind mate-
rial of varying densities. Materials such as carpet,
wire metal mesh backing, damp walls, and stucco
may affect readings. Alternating surfaces, such
as thick grout lines or extremely heavy plaster on
drywall, may be detected or show as metal or studs.
1.Turn on the Sub-Scanner.
2.Select Metal mode (default).
3.Standard depth of
scan (up to 4" deep
scan) is defaulted.
Press the Metal
button to switch
to Deep depth of
scan (up to 6" deep
scan).
NOTE:
Deep mode scans may display more
"noise" due to the higher sensitivity of the scan.
4.Hold the Sub-Scanner
against
the surface and
press the Calibrate button.
5.The Sub-Scanner
must remain flat
against and in con-
tact with surface
during entire scan.
If CALIBRATION
E R R O R i s d i s -
played, the tool was
placed in an area
where metal is pres-
ent. Move the Sub-
Scanner to another
position and restart
calibration.
6.When SCANNING is displayed, move the Sub-
Scanner across the surface. Keep your free hand
and other objects at least 6” (152 mm) away to
avoid false readings.
7.When metal is detected, the type (ferrous or non-
ferrous) and depth
are displayed. Con-
tinue to move the
Sub-Scanner across
the surface. As you
approach metal,
the distance will de-
crease. As you move
away from the met-
al, the distance will
increase. When the
minimum distance
and indicator arrow
are displayed, the
Sub-Scanner is di-
rectly over the metal
at that distance. The
minimum distance and indicator arrow may ap-
pear for a short span; the precise center is the
center of this span.
NOTE: There may be additional metal material
deeper in the wall, but only the closest metal
object’s depth is displayed.

WARNING: Changes or modi
fi
cations to this unit not ex-
pressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15

which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for help.
• Have your Sub-Scanner serviced by a qualifi ed
repair person using only identical replacement
parts.
This will ensure that the safety of the tool is
maintained.
• Do not disassemble.
Incorrect reassembly may
result in the risk of electric shock or
fi
re. If it is dam-
aged, take it to a
