Using the Multifunction/Audio priority switch

the multifunction/audio priority switch has three positions:

Multifunction/Audio priority switch

top position:
an active intercom will mute the aux audio

middle position:
an active intercom will be mixed with the aux audio

bottom position:
the aux audio input is off. only intercom audio will be heard

Intercom audio will never be muted, regardless of the position of the Multifunction switch.

note: on the bluetooth® control module, when a bluetooth® wireless technology call is present, the audio from the call mutes the signal on the aux audio input. in either the top or middle position of the multifunction switch, both the intercom and the bluetooth® wireless technology signal are heard as mixed.
