Position boom microphone 1/8 inch from lips and center it over your mouth for best
results. Noise canceling microphones will not operate correctly if they are more than
1/8 inch from your mouth. While speaking into the microphone, adjust the volume
control to a comfortable level. Adjust the squelch control as far clockwise as possible
while still blocking out background noise. Only adjust the squelch while no one is
talking. If the squelch is set too high (counter clockwise) your voice will cut out unless
you talk very loudly. If the squelch is set too low (clockwise) you will occasionally
hear background noise through the headphones while no one is speaking.
Normal radio use is unaffected by installation of the intercom, but passengers will
now be able to hear the aircraft radio when the isolate switch is in the ALL position
(see isolate and muting matrix on page 7). The intercom volume control does not
affect radio transmit volume. To transmit on the radio, simply press the PTT switch
associated with your headset position. There is no need (but is advisable) for the
passengers to stop talking while the pilot (or copilot) is transmitting. Only the person
whose PTT switch is depressed will be heard over the radio, thus an instructor can
talk to a student pilot while the student is transmitting without the instructors voice
being heard over the radio. If both the pilot and copilot have their PTT’s depressed
at the same time, both voices will be transmitted.
For optimum results from your iNova intercom, use high quality, stereo headsets such
as the Flightcom Denali.
