NOTE: Unauthorized use of cellular
telephone devices in aircraft is subject
to FCC enforcement action, which
may include a $10,000 fine per

endorse using unapproved cellular
telephone equipment in flight, and
takes no responsibility for the user's

Intercom System
‡ IntelliVox™ VOX-Squelch@@
No adjustment of the IntelliVox™
squelch control is necessary. Through
three individual signal processors, the
ambient noise appearing in all six
microphones is constantly being
sampled. Non voice signals are
blocked. When someone speaks, only
their microphone circuit opens,
allowing him or her to communicate
on the intercom.
NOTE: InteliVox™ is a registered
trademark of PS Engineering, Inc. and
is used by permission
The system is designed to block
continuous tones; therefore people
humming or whistling in monotone
may be blocked after a few moments.
For best performance, the headset
microphone must be placed within º
inch of your lips, preferably against
them. It is also a good idea to keep
the microphone out of a direct wind
path. Moving your head through a
vent air stream may cause the
IntelliVox™ to open momentarily. This
is normal.
For optimum microphone
performance, Honeywell recommends
installation of a Microphone Muff Kit
8
from Oregon Aero (1-800-888-6910).
This will not only optimize VOX
acoustic performance, but will
improve the overall clarity of all your
communications.
Volume Control
The volume control knob adjusts
the loudness of the intercom for the
pilot and copilot only. It has no effect
on selected radio levels, music input
levels or passengers' volume level.
Adjust the radios and intercom
volume for a comfortable listening
level for the pilot. Most general
aviation headsets today have built-in
volume controls; therefore, passenger
volume can be adjusted at the
headset.
Mono headsets in Stereo
Installation
All passenger headsets are
connected in parallel. Therefore, if a
monaural headset is plugged in to a
Stereo KMA 28 installation, one
channel will be shorted. Although no
damage to the unit will occur, all
passengers will lose one channel.
Intercom Modes
The lower switch on the left side
is a 3-position mode switch that
allows the pilot to tailor the intercom
function to best meet the current
cockpit situation.
ISO (Up Position): The pilot is
isolated from the intercom and is
connected only to the aircraft radio
system. He will hear the aircraft radio
reception (and sidetone during radio
transmissions). Copilot will hear
passengers' intercom and
Entertainment 1, while passengers
will hear copilot intercom and
Entertainment 2. Neither will hear
