¼-inch of your lips, preferably against them. It is im-
portant to have the microphone element parallel to your
mouth, and not twisted inside the cover.
Note: For optimum microphone performance, we rec-
ommend use of a Microphone Muff Kit from Oregon
Aero (1-800-888-6910,
www.oregonaero.com ). This
will not only optimize VOX performance, but will im-
prove the overall clarity of all your communications.
You should also keep the microphone out of a direct wind. Moving your
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
pilot and copilot. 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. It has no effect on radio or music levels.
Mono Headsets in Stereo Installation
The pilot and copilot positions work with stereo or mono headsets. If a pas-
senger’s monaural headset is plugged in to a KMA 30 Stereo installation,
one channel will be shorted and all passengers will lose one channel unless
they switch to the “MONO” mode on the headset.
Intercom Modes (8)
The intercom has three modes, ISO, ALL
and CRW. The description of the intercom
mode function is valid only when the unit is
not in the "Split" mode. In split mode, the
pilot and copilot intercom is controlled with
the Mute button.
The ICS button cycles through the intercom
modes, from top to bottom and then back up.
I
SO : The pilot is isolated from the intercom and is connected only to the air-
craft radio system. He hears the radios (and sidetone during radio transmis-
sions). The copilot and passengers will hear the music sources as configured
by the audio panel configuration Function keys. See page 15—Smart Func-
tion Keys for more details.
While in ISO Mode, the pilot can elect to hear music #1. First, be sure that
the ISO mode is selected. Then press and hold the TEL button, then hold the
