Monitor Mode
When interfaced with the M760R VHF COM radio as Com 1, the standby
frequency can be monitored by holding the C2 Receive button for the Mi-
croair for more than one second (or until the indicator becomes active).
Intercom Operation (8)
IntelliVox® VOX-Squelch
No manual adjustment of the IntelliVox® squelch control is possible.
Through individual signal processors, the ambient noise appearing in all four
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 moments.
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)).
NOTE
It is also a good idea to keep the microphone out of a direct wind path. Mov-
ing your head through a vent 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). It loves airplane noise! Therefore, it may not recognize
speech and clip syllables in a quiet cabin, such as in the hangar, or without
the engine running. This is normal.
For optimum microphone performance, PS Engineering recommends instal-
lation of a Microphone Muff Kit from Oregon Aero (1-800-888-6910). This
