STEP 2: Apply 3M Backing

Apply supplied 3M backing on both the sensor and magnet side. Ensure you pop out the middle piece on the 3M Backing on the sensor side so you have access to the on off switch and paring button. 3M Backing should only be placed once to ensure maximum strength so be 100% sure of placement before sticking on door or window.

STEP 3: Place on Window or Door

Place on door or window. It does not matter which side goes on the frame and door/window. Make sure the arrows on both the sensor and magnet are aligned and ensure they are no father than 1/2 inch apart. Lastly ensure that both the magnet and sensor side are level with each other for best results. If you need to raise one side higher, you can layer 3M backing on top each other or use a thicker 3M tape.
