PAC45 Pilot Guide
HRTF button for > 1 second on the pilot’s panel until the HRTF button and
all COM nomenclature start blinking green.
Rotate the desired COM receive volume knob so the pointer indicates the
approximate location of the desired location. A voice announcement will
accompany the knob rotation with the clock positions. Received audio will
then be presented from that location.
Press the HRTF button again to exit the mode. The audio Controller will
remember last state through power cycles.
Navaid Audio Selection
Navigation receivers are selected in the same manner
as the communication receiver, push on/push off the
knob associated with the desired navigational aid, and
rotate to adjust the receiver volume.
Telephone control
The volume control selector connects the audio control-
ler to either a Bluetooth®-enabled cell phone or a wired
cellular/satellite phone.
Push to pop out the volume control to select (answer or
make phone call) and adjust the receive audio volume. This
knob must be out to use the telephone function.
To hear the ringer of the Bluetooth phone, the volume con-
trol should be around the 12 o’clock position. Selecting the
TEL switch in the OUT position is not required.
Intercom Operation
IntelliVox® Intercom 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, placing their
voice on the intercom.
The system is designed to block continuous tones; therefore people hum-
ming 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-214A,
§1.3.1.1 (a)).
