Operating Tips

• Use only D WALT 12V Max* lithium-ion battery.
E
• Ensure the D WALT battery is in good working condition. If the
E
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"
(40 cm) or 24" (60 cm) apart and are 1-1/2" (38 mm) 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.
