tion. When a com is selected for receive, it will stay selected until manually
deselected, even if you select, and then deselect its transmitter.
Unless the audio panel is in "split" mode, the KMA 30 gives priority to the
pilot's radio Push-To-Talk (PTT).
If the MONITOR function is activated (see pg 16 for more details), the au-
dio from this radio will be muted when the primary radio (selected for trans-
mit) is receiving a signal.
In TEL mode, the pilot is connected to the cell phone, but still hears the
COM radios selected. The radio PTT will switch the mic to the selected com,
and allow continued aircraft com-
munications to continue. (See Page

Audio Selector (4)
These buttons select the switched
navigation receivers. The DME
input (if present) is also shared with AUX. In SPLIT mode, only the pilot
will hear selected navigation audio.
Cockpit Speaker (5)
This switch will place all selected audio on the cockpit
speaker when this switch is selected. In "Split" mode, the
speaker carries the same audio as the pilot.
Depending on installation, important audio alerts such as radar altimeter or
autopilot disconnect will come over the speaker even if it is not selected,
while other unswitched inputs, will only be present if the SPR button is se-
lected. Consult your professional avionics installer for these important con-
figuration details.
Intercom Operation
IntelliVox® VOX-Squelch
IntelliVox® is a proprietary intercom squelch control. Through the use of
digital processors, each microphone is monitored, and opens instantly when
human speech is detected. This results in seamless conversations aboard the
airplane for crew and passengers, without syllable clipping or fatigue-
inducing noise.
No adjustment of the IntelliVox® squelch control is necessary. There is no
field adjustment. The system is designed to block continuous tones, therefore
people humming or whistling in monotone may be blocked after a few mo-
ments.
For consistent performance, any headset microphone must be placed within
