2)Removal of the old doorbell
Before installing the doorbell, please use a Phillips
screwdriver to remove the old doorbell from the wall
or door and remove all other hardware. If your old
doorbell is also a visual doorbell, please be sure to
remove all connectors, as the connectors on the old
unit may not work with this product.
If there is no indicator label for the breaker on the line
where the doorbell is located, try pressing the old
doorbell to make sure the power is off.
