Make sure the garage door is closed and the surface is clean and dry, and the control panel is less than 100 ft. away from the door. Position the sensor on the top of the inside of your garage door with the arrow on the sensor pointing up. If you have a paneled garage door, place the sensor either at the bottom of the top panel or at the top of the second panel as indicated by the two dots in the diagram below. Once you’ve removed the wax backing from the adhesive, press the sensor firmly against the door for 30 seconds.
