2.9.1 Required Test Equipment
In order to return an aircraft to service after installation of the PMA6000-series with marker beacon re-
ceiver, the installer must have access to a Marker Beacon signal generator:
a. IFR NAV401L, NAV402AP, IFR4000
b. TIC T-30D, T-36C
Equivalent test equipment is acceptable as long as the testing requirements can be met.
2.9.2 Power Test
After wiring is complete, verify power is ONLY on pin 20 of the bottom connector, and airframe ground
on bottom connector pin Z. Failure to do so will cause serious internal damage and void PS Engineering's
warranty.

1. Apply power to the aircraft and avionics.
2. Plug headsets into the pilot, copilot and passenger positions.
3. With avionics on, and the audio panel off, verify that the pilot can transmit and receive on COM 1,
through the headset, indicating proper “fail-safe” operation.
4. Rotate the Mic Selector Switch to the Com 1 position.
5. Verify that the C1 light comes on. Verify that the power LED (Light Emitting Diode) in the intercom
section illuminates green. If the LED is red, stop testing and troubleshoot the microphone PTT instal-
lation.
6. Verify proper transmit and receive operation on the copilot position, noting that the copilot PTT
switch allows proper transmission on the selected transceiver.
7. Verify that pushing the C2 button causes the button to illuminate, and the Com 2 receiver to be heard.
Verify operation on Com 1 from the pilot position.
8. Repeat for Com 2 and TEL, (if installed).
9. Rotate the mic selector switch to the C
OM 1/2 position. Verify that the pilot communicates on Com 1
and the copilot on Com 2.
10. Rotate the mic selector switch to the C
OM 2/1 position. Verify that the pilot communicates on Com 2
and the copilot on Com 1.
11. If PMA6000C or PMA6000MC. Go to section 2.10.1 Otherwise, rotate the mic selector switch to the
TEL/COM 1 position. Verify that the pilot communicates on the transceiver in the TEL position and the
copilot on Com 1.
12. Verify proper operation of all receiver sources by selecting them using the keypad. Note that the but-
ton for the receiver sources stays in, and the button illuminates to show which source is in use.
13. Push in the S (SPR) button. Verify that all selected audio is heard in the cockpit speaker. Verify that
the audio mutes when the mic is keyed.
14. Verify that the LED in the intercom changes from green to red when a microphone is keyed. NOTE:
LED does not change color in "Split Mode".
15. Verify proper Intercom system operation in the A
LL, ISO And CREW modes.
16. Verify that the audio selector panel system does not adversely affect any other aircraft system by sys-
tematically switching the unit on and off, while monitoring the other avionics and electrical equipment
on the aircraft.
