approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
Read operator’s manual carefully. Learn the applications
and limitations, as well as the specific potential
hazards, related to this product. Following this rule will
reduce the risk of electric shock, fire, or serious injury.
Do not operate battery products in explosive

which may ignite the dust or fumes.
Do not disassemble the product. Contact with internal
parts may increase the risk of electric shock or cause
damage to the product.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the

Do not store the product in an area of high heat or
humidity. Do not expose the product to extended high
heat from the sun (such as on a vehicle dashboard.)
To reduce the risk of serious personal injury, do not
store outside or in vehicles. Damage to the product or
the battery can result.
Do not expose product to rain or wet conditions. Water
entering a product will increase the risk of electric shock.
Use the product in accordance with these instructions
and in the manner intended for the product, taking into
account the environmental conditions and the work to
be performed. Use of the product for operations different
from those intended could result in a hazardous situation.

of ignition, such as a pilot light. To reduce the risk of
serious personal injury, never use any battery device in
the presence of open flame. An exploded battery can
propel debris and chemicals. If exposed, flush with water
immediately.
Under extreme usage or temperature conditions, bat-
tery leakage may occur. If liquid comes in contact with
your skin, wash immediately with soap and water. If
liquid gets into your eyes, flush them with clean water
for at least 10 minutes, then seek immediate medical
attention. Following this rule will reduce the risk of serious
personal injury.

MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
STORAGE
Store in a cool, dry location to prevent condensation or mold
from forming inside the product.
Do not store the device at temperatures greater than 122º
F (such as on a dashboard or vehicle interior).
BATTERY RECYCLING
Consult the Earth 911 website (www.earth911.com) or your
local waste authority for information regarding available
recycling and/or disposal options.
WARNING:
Do not attempt to destroy or disassemble batteries or
remove any of their components. All batteries must be
recycled or disposed of properly. Do not discard large
amounts of used batteries together. “Dead” batteries
often have residual charge. When grouped together, these
batteries can become “live” and pose a risk of possible
serious injury.
Locating studs or joists:
Once calibration is complete, begin to slowly move the
unit in a straight line to the left or right against the wall.
As you near a stud, the graduated display will begin to
light up. When you reach the center of the stud, the dis-
play will fully light up and the word STUD CENTER will
appear at the top.
To mark where center is, depress the button at the bottom
of the unit to make a mark on the wall at the point where
STUD CENTER appeared on the display. This will leave
a small dimple on the wall surface.
