Clear-Com main stations, power supplies and certain remote stations each have
an auxiliary program input with its own volume control, which allows an
external audio source to be fed to the intercom system.
Visual signal circuitry (call lights), a standard feature on all main and remote
stations, allows the user to attract the attention of operators who have removed
their headsets.
