OPERATION 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 display 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. Fig. 4 "No Stud" Indicator Fig. 5 Calibrating "Stud Center" Indicator MAINTENANCE WARNING: When servicing, use only identical replacement parts. Use of any other parts could create a hazard or cause product damage. BATTERY RECYCLING Consult the Earth 911 website (www.earth911.com) or your local waste authority for information regarding available recycling and/or disposal options. 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. 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. Do not store the device at temperatures greater than 122º F (such as on a dashboard or vehicle interior). 5 - English
