dren. The digital clock can also be used as a sleep
timer to turn music off at a certain time. This fea-

BB. Self Diagnostic Troubleshooting Circuitry

For proper performance and operation of an
Intercom, it is important that all wires are securely
attached to the proper terminal. Otherwise, certain
features of the intercom may not work, there could
be humming or no sound at all. NuTone’s self diag-
nostic circuitry allows the installer to easily check
the installation and if there is a misconnected wire,
identify which room is affecting the system. This
helps ensure that when the installer leaves, your
system is operating as it was designed to.
