Heath Zenith 7560 Mode D'emploi page 5

A small electrical component called a "diode" is required for this chime to play the entire tune. This diode must be
installed on the terminal screws of the front door push button (see Figure 3). If not already installed on push button, attach
supplied diode as shown below. If, with the diode in place, the chime does not play the complete melody, see Wired Troubleshooting,
page 10.
