Intercom Operation
IntelliVox® VOX-Squelch
No adjustment of the IntelliVox® squelch control is necessary. There
is no field adjustment. 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, placing their voice on the intercom.
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 ¼-inch of your lips, preferably against them. (ref: RTCA/DO-
214, 1.3.1.1 (a)). It is important to have the microphone element par-
allel to your mouth, and not twisted inside the cover.

Note: For optimum microphone performance, we recommend
use of a Microphone Muff Kit from Oregon Aero (1-800-888-
6910). This will not only optimize VOX performance, but will
improve the overall clarity of all your communications.
