Intercom Volume Control (7)
The inner volume control knob adjusts the loudness of the intercom for the crewmember connected to the
audio panel. It has no effect on selected radio levels, music input levels or passengers' volume level.
The outer volume control knob controls intercom volume for the passengers connected to the secondary
(copilot’s) audio panel. It has no effect on radio or music levels. Pilot’s outer knob is not active.
Adjust the radios and intercom volume for a comfortable listening level. Most general aviation headsets
today have built-in volume controls; therefore, volume also can be further adjusted at the individual head-
set.

Intercom Modes (8)
