After wiring is complete, verify power is ONLY on pin 21 of the connector, and airframe ground on bot-
tom connector pin 22. Failure to do so will cause serious internal damage and void PS Engineering's war-
ranty.

1. Apply power to the aircraft and avionics. Leave PCD7100 off.
2. Plug headsets into the pilot, copilot, and occupied passenger positions.
3. Verify correct fail-safe operation by listening and transmitting on the aircraft radios in the pilot’s head-
set with the unit off. The audio will only be presented to the pilot’s right ear, in stereo mode.
4. Switch on the PCD7100. Verify that the STOP LED (Light Emitting Diode) shows green if there is a
CD in the unit, or the Eject LED if there is not a CD inside.
5. Verify proper transmit and receive operation from the pilot and copilot positions, noting that the copi-
lot PTT switch allows proper transmission on the selected transceiver.
