SAFETY INSTRUCTIONS

Please read all instructions prior to operating the STRAIT-LINE® SF150. Keep out of reach if children.

Remove the battery when storing the tool for an extended time to avoid damage to the tool should the battery deteriorate.
This STRAIT-LINE® Stud Finder is designed for use on dry interior walls only. Do not nail, drill, or cut into a wall that has electrical wiring or hidden water pipes as this may result in serious injury. If electrical wiring is contained in the wall, turn the circuit off before cutting into the wall.
It is possible for the Stud-Finder to detect wiring and / or water pipes, but this tool is primarily designed for detecting wood stud on drywall up to 5/8" deep. Studs or joists are normally spaced at 16" (410mm) or 24"(610mm) apart and have an edge width of 1-1/2". Anything detected closer together or a different width may not be a stud, joist or firebreak.

To Scan a Wall

This STRAIT-LINE® stud finder utilizes ACCUSCAN® technology to detect objects behind surfaces. ACCUSCAN® scanning modes are tuned to detect objects behind specific surfaces. Select the mode that matches the type of surface you are using the tool on.

3. Upon successful calibration, the upper green LED goes OFF and the "beep" sound stops.
4. To start scanning, hold Stud Finder on testing surface and slowly slide itsideways.
5. When stud edge is detected, the upper green indicator LED will turn onand "beep" sound will be generated continuously. Push "Mark" button to mark spot. Continue to move slowly in the same direction until the LED lights turn off and the "beeping" stops.
6. Move in reverse to locate the other edge. Mark this spot again. User cannow find the middle point for nailing or drilling.

• While scanning, the unit must remain in contact with the surface.
• If the tool lifts from the surface, the unit will turn off and recalibration is required.
• If the green indicator light does not turn off during calibration, you may have calibrated over a damp surface. Turn off the unit and start calibration again by moving the unit 5" to 8" left.
• When the unit is beeping continuously during calibration, you might have calibrated over a metal pipe. Move the unit 5" to 8" left or right, turn off the unit and start calibration again.
• When holding the unit, your hand should remain in the same position during calibration and scanning.
