Abstract
A doorbell chime (100) can comprise a chassis (101), a cover (104) having a mechanical-cover identifier (105, 106), a mechanical-cover identifier detector (103) (to detect when the cover is at least substantially disposed in the installed position), and a chime (102) mounted in the chassis. This chime is configured to operate in a first mode of operation (302) when the mechanical-cover identifier detector detects the cover and in a second mode of operation (303) (that is different than the first mode of operation) when the mechanical-cover identifier detector does not detect the cover.
