English 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" (38 mm) 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 uninsulated, 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. CAUTION: When not in use, place hand-held wall scanner on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knocked over. • The label on your tool may include the following symbols. The symbols and their definitions are as follows: V volts A amperes Hz hertz W watts min minutes or AC.......... alternating or DC ... direct current current Class I Construction or AC/DC... alternating grounded) or direct Class II Construction current (double insulated) no no load .../min .......... per minute speed BPM beats per minute n rated IPM impacts per minute speed RPM revolutions per earthing minute terminal sfpm surface feet safety alert per minute symbol SPM strokes per minute Detection through Special Surface Conditions WALLPAPER The hand-held wall scanner will function normally on walls covered with wallpaper or fabric, unless the materials are metallic foil, contain metallic fibers or are still wet after application. 3
