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" (38mm) 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.

Important Safety Instructions for All
Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains important
safety and operating instruc tions for battery chargers.
• Before using charger, read all instructions and cautionary markings
on charger, battery pack, and product using battery pack.
WARNING: Shock hazard. Do not allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Burn hazard. To reduce the risk of injury, charge only
D
EWALT rechargeable batteries. Other types of batteries may burst
causing personal injury and damage.
NOTICE: Under certain conditions, with the charger plugged in to the
power supply, the charger can be shorted by foreign material. Foreign
materials of a conductive nature such as, but not limited to, grinding
dust, metal chips, steel wool, aluminum foil, or any buildup of metallic
particles should be kept away from charger cavities. Always unplug the
charger from the power supply when there is no battery pack in the
cavity. Unplug charger before attempting to clean.
• DO NOT attempt to charge the battery pack with any
chargers other than the ones in this manual. The charger and
battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than
charging D
EWALT rechargeable batteries. Any other uses may
result in risk of fire, electric shock or electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
• Make sure that cord is located so that it will not be stepped
on, tripped over, or otherwise subjected to damage or
stress.
• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in risk of
fire, electric shock, or electrocution.
• When operating a charger outdoors, use an extension cord
suitable for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
• An extension cord must have adequate wire size (AWG
or American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. An undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the
total length, be sure each individual extension contains at least the
minimum wire size. The following table shows the correct size to
use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number,
the heavier the cord.
Minimum Gauge for Cord Sets

• Do not operate charger with damaged cord or plug.
• Do not operate charger if it has received a sharp blow, been
dropped, or otherwise damaged in any way. Take it to an
authorized service center.
• Do not disassemble charger; take it to an authorized service
center when service or repair is required. Incorrect reassembly
may result in a risk of electric shock, electrocution or fire.
• Disconnect the charger from the outlet before attempting
any cleaning. This will reduce the risk of electric shock.
Removing the battery pack will not reduce this risk.
• NEVER attempt to connect two chargers together.
• The charger is designed to operate on standard 120V
household electrical power. Do not attempt to use it on any
other voltage. This does not apply to the vehicular charger.
Chargers
Your tool uses a DEWALT charger. Be sure to read all safety instructions
before using your charger. Consult the chart on the back cover of this
manual for compatibility of chargers and battery packs.
FIG. 1
A
Charging Procedure (Fig. 1)
1. Plug the charger into an appropriate outlet before inserting battery
pack.
2. Insert the battery pack (A) into the charger, as shown in Figure 1,
making sure the pack is fully seated in charger. The red (charging)
light will blink continuously indicating that the charging process
has started.
3. The completion of charge will be indicated by the red light
remaining ON continuously. The pack is fully charged and may be
used at this time or left in the charger.
Charge Indicators
Some chargers are designed to detect certain problems that can arise
with battery packs. Problems are indicated by the red light flashing at
a fast rate. If this occurs, re-insert battery pack into the charger. If the
problem persists, try a different battery pack to determine if the charger
is OK. If the new pack charges correctly, then the original pack is
defective and should be returned to a service center or other collection
site for recycling. If the new battery pack elicits the same trouble
indication as the original, have the charger tested at an authorized
service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger
detects a battery that is hot, it automatically starts a Hot Pack Delay,
suspending charging until the battery has cooled. After the battery
has cooled, the charger automatically switches to the Pack Charging
mode. This feature ensures maximum battery life. The red light flashes
long, then short while in the Hot/Cold Pack Delay mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge
indicator showing Pack Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function
but should not be expected to perform as much work.
8
English
FAULTY BATTERY PACKS: This charger will not charge a faulty
battery pack. The charger will indicate faulty battery pack by refusing
to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 65 °F and
75 °F (18–24 °C). DO NOT charge the battery pack in an air
temperature below +40 °F (+4.5 °C), or above +105 °F (+40.5 °C).
This is important and will prevent serious damage to the battery
pack.
2. The charger and battery pack may become warm to touch while
charging. This is a normal condition, and does not indicate a
problem. To facilitate the cooling of the battery pack after use,
avoid placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or other
appliance;
b. Check to see if receptacle is connected to a light switch which
turns power off when you turn out the lights;
c. Move charger and battery pack to a location where the
surrounding air temperature is approximately 65 °F–75 °F
(18–24 °C);
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
4. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack
whenever you desire with no adverse affect on the battery pack.
5. Foreign materials of a conductive nature such as, but not limited
to, grinding dust, metal chips, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger
cavities. Always unplug the charger from the power supply when
there is no battery pack in the cavity. Unplug charger before
attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don’t allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Never attempt to open the battery pack for any reason.
If the plastic housing of the battery pack breaks or cracks, return to
a service center for recycling.
Storage Recommendations
1. The best storage place is one that is cool and dry away from direct
sunlight and excess heat or cold.
2. For long storage, it is recommended to store a fully charged
battery pack in a cool dry place out of the charger for optimal
results.
NOTE: Battery packs should not be stored completely depleted of
charge. The battery pack will need to be recharged before use.

The confidence meter (P) gives a relative indication of signal strength.
A fully lit confidence meter indicates a strong data signal and high
confidence of the material identified below the surface.
A partially lit confidence meter indicates a weaker signal and less
confidence of the material identified below the wall.
To improve the signal strength, follow these tips:
– Scan in a straight line, either horizontal or vertical.
– Scan uniformly without lifting from the surface of the wall.
– Always scan SLOWLY to achieve maximum sensitivity.

Battery Fuel Gauge
The display on the hand-held radar scanner includes a
battery fuel gauge (R) which consists of four yellow
segments that indicate the level of charge remaining in the
12V Max* battery pack. When the level of charge in the
battery is below the usable limit, the last segment of the
battery fuel gauge will turn red to indicate that the battery
will need to be recharged.
NOTE: The battery fuel gauge is only an indication of the charge left
on the battery pack. It does not indicate product functionality and is
subject to variation based on product components, temperature and
end-user application.
Tracking Bar
The tracking bar (S) at the bottom of the main viewing screen gives a
macro overview of the number of objects located during the pre-scan
data mapping process.
The current position of the hand-held radar scanner is indicated by the
brackets and shaded area.
The tracking bar can be helpful in indicating which way to move the
hand-held radar scanner to identify additional objects behind the wall
surface.

Operating Tips
• Use only DEWALT 12V Max* lithium-ion battery.
• Ensure the D
EWALT battery is in good working condition. If the
battery fuel gauge (R) on the main viewing screen has only one red
segment lit, the battery needs to be recharged.
• Scan in a straight line, either horizontal or vertical.
• Scan uniformly without lifting from the surface of the wall.
• Always scan SLOWLY to achieve maximum sensitivity.
• Do not touch the surface being scanned with your other hand or
any other part of the body as it could interfere with scanning.
• Refer to construction plans, visible exits of wires and pipes and
construction techniques. Studs are normally spaced either 16"
(40cm) or 24" (60 cm) apart and are 1-1/2" (38mm) wide. Doors
and windows are often constructed with studs and headers which
are closer together.
• Avoid scanning through materials which have inconsistent density
such as carpet with padding, excessively thick plaster and lath,
freshly painted walls or metallic wall coverings.
• Avoid wearing jewelry such as rings or watches. The metal may
cause inaccurate detection.
• Protect against moisture and direct sunlight.
• Do not place stickers, decals, paint or name plates, especially
metal ones, on the sensor area of the back of the tool.
MAINTENANCE
Cleaning
WARNING: Blow dirt and dust off with clean, dry air at least once
a week. To minimize the risk of eye injury, always wear ANSI Z87.1
approved eye protection when performing this.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the plastic materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.
CHARGER CLEANING INSTRUCTIONS
WARNING: Shock hazard. Disconnect the charger from the AC
outlet before cleaning. Dirt and grease may be removed from the
exterior of the charger using a cloth or soft non-metallic brush. Do
not use water or any cleaning solutions.
