Here's a manual link to this great service.
Hi Gene, Place the unit flat against the wall.
This limited warranty stud stanley does not cover products that are improperly used, abused, altered or repaired.
Stanley warrants this product for a period of (2) years sensor against deficiencies in material and workmanship.In addition to the warranty, stanley Lasers are covered by: sensor 30-Day Money Back Guarantee.Problem is that this unit is very unreliable and does not work as advertised most of the time.If it is an older home this was used often as a backing stud for plaster manual instead of ank you.
You must first place the stud stud finder against the stanley wall, press the button and wait for the light and audio signal to stop.
The model 77-720 sensor model does detect electrical wiring but not the 77-110.

Then move it back and forth in a wide enough arc to be sure that you have crossed a stud, turning up the sensitivity ever so slightly until you get a tone when you cross a stud.
The LED will come on for a second stanley stud sensor 200 manual or two then go out.
