for the microphone and headphone jacks. Combining these two wires WILL cause loud oscillations and degrade the intercom function. The oscillation is caused by the cross-coupling between the large headphone signal and the small microphone signal. The resulting feedback is a high-pitched squeal that varies with the volume controls. Due to the variety of the radio equipment found in today's general aviation aircraft, there is the potential of both radiated and conducted noise interference.

2.Plug headsets into the pilot, copilot and passenger positions. 3.Verify that the pilot position can transmit and receive with the PM1000II in the OFF position (left hand volume knob fully counterclockwise). 4.Rotate the pilot volume clockwise, about half way. Verify that the Pwr/Xmt light comes on, and shows green. If the LED is red, stop testing and trouble-shoot the microphone PTT installation. 5.Verify that the pilot can transmit and receive on the com transceivers. 6.
