2.8.1 Required Test Equipment

In order to return an aircraft to service after installation of the PAC45D, the installer must have
access to headset(s), and be able to establish 2-way communications on appropriate radios.
Equivalent test equipment is acceptable as long as the testing requirements can be met.

2.8.2 Audio controller Test

The IntelliVOX® is designed for ambient noise levels of 80 dB or above. Therefore, some clipping
may occur in a quiet cabin, such as without the engine running, in a hangar. This is normal.
Use of a Stereo headset is required to obtain full effect of MultiTalker processing.
1. Apply power to the aircraft and avionics.
2. Plug stereo headsets into the pilot, copilot, and occupied passenger positions, or monaural
if not using HRTF feature.
3. Verify fail-safe operation by receiving and transmitting on com 1 from the pilot position,
with the audio controller power off /EMG mode. The Com audio will be present in one ear
cup only if stereo headset and both ear cups if using monaural headsets.
4. Switch on the unit by turning the XMT select knob to the full CCW position (COM 1).
5. Check intercom operation.
6. Verify that the COM 1 legend in both the XMT and RCV change to green. Verify that transmit
indicator is not flashing green... If the LED is flashing green, stop testing and troubleshoot
the microphone PTT installation. If for any reason the transmit PTTs are stuck, then they will
disconnect after 35 seconds.
7. Verify proper transmit and receive operation from the copilot position, noting that the copi-
lot PTT switch allows proper transmission on the selected transceiver. Verify that the Xmt
legend flashes green when the copilot is transmitting.
8. Rotate the XMT knob to the next transceiver position and verify the indicators change to
track the selection, and Com 2 receiver is heard.
9. Repeat for remaining transceivers.
10. Verify proper operation of all receiver sources by selecting them using the appropriate knob.
11. Verify proper Intercom system operation in the A
12. Verify that the audio selector panel system does not adversely affect any other aircraft sys-
tem by systematically switching the unit on and off, while monitoring the other avionics and
electrical equipment on the aircraft.

2.8.3 Bluetooth Checkout

Verify that the PAC45D will "pair" with a Bluetooth device, and interface with cellular phone and
Music source. See § 3.7.2
If PAC45D is not connecting, resetting the Bluetooth memory might be required. Hold down TEL
& ICS buttons for 3 seconds until there is a chime in pilot headset. You will also need to "Forget
Device" on the phone.
