head through an air stream may cause the IntelliVox® to open momentarily.
This is normal. The IntelliVox® is designed to work with normal aircraft
cabin noise levels (70 dB and above). Therefore, it may not always recognize
speech and clip syllables in a quiet area, such as in the hangar, or without the
engine running. This is also normal.
Intercom Volume Control (7)
The small 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 larger, outer volume control knob controls intercom volume for the pas-
sengers on the copilot audio panel only. It has no effect on radio or music
levels. The pilot panel outer knob has no effect.
Mono Headsets in Stereo Installation
The pilot and copilot positions work with stereo or mono headsets.
Intercom Modes (8)
In each audio panel, a short press of the ICS button toggles between Isolate
(ISO) and Crew (CRW) intercom modes.
In ISO mode, the pilot or copilot hear selected radios, unswitched audio, and
can hear music if playing, if activated. They do not hear any intercom audio.
In CRW mode, the pilot and copilot audio intercom stations are connected.
Each crew member continues to hear their selected receiver and unswitched
connected to their audio panel. They can listen to the music connected to
their panel.
Either audio panel can activate the CREW mode, and if either crew member
pushes the ICS button to the ISO mode then both panels will enter the ISO
mode.
Passenger Intercom (if equipped)
Intercom mode is indicated by green ISO or CRW LEDs.
If equipped with an expansion unit, passengers can be added to the intercom
by holding the ICS button for more than one second. When passengers are
on the intercom, the PAX LED is also on along with the ISO or CREW
green LED.
To place all aircraft stations on the intercom, the audio panels should be in
CRW and PAX (long press either ICS button on either audio panel).
Any time the ICS button is pressed, the intercom mode will drop the passen-
gers. The next press of the ICS button will toggle between ISO and CRW.
The passengers can also be removed from the crew intercom by holding the
ICS button for more than one second.
NOTE: Passenger intercom requires an IntelliPAX passenger intercom.
