How do I perform a factory reset?

To perform a factory reset, remove one battery (or turn off the power to a plug-in doorbell). Press and hold the settings button settings whilst replacing the battery (or turning on the power). An Amber light will flash, either from the small LED indicator on the side of the doorbell, or from the Halo Light (Depending on product type). After this, you’ll have to re-link your push button or other devices such as wireless motion sensors and/or wireless door and window sensors.
