the back of the doorbell unit over the mounting block. There is a square opening that the
block will fit into position that opening over the mounting block. Next slide the doorbell
unit down on the block about 1/8 inch, the doorbell unit should stay on by itself if
installed correctly.

install the long screw in the top hole, and replace the screw cover.
