SECTION 4 – Installation Checkout Procedure
1. Introduction
This procedure should be followed to verify installation of the system.
Procedure
(1) Install all LRU’s and antenna systems.
(2) Verify grounding on antennas is <5 mohms.
(3) Verify grounding between LRU’s and airframe is <.5mohms.
(4) Enable power bus.
(5) Verify display units turn on and initialize. Perform “LEARN” mode if unit requests
it.
(6) Configure the unit for DUAL or SINGLE mice mode. See section 6 for more
information.
(7) Configure the unit for LOCK VOLUME setting.
(8) Press the volume knob for FM1. Verify the discreet RX indicator for FM1 is
displayed and that noise is heard in the headset. Vary FM1 volume knob (if
LOCK VOLUME is set to NO) or the volume knob on the audio or both to very
volume level can be controlled. Perform this test for both FM1 and FM2.
(9) Connect communication analyzer directly into FM1 antenna port (J103). Inject a
signal into the transceiver and verify the reception at .6 uV unsquelches the
audio and the signal is heard in the headset.
(10) Transmit with FM1 and verify power levels, Frequency, and deviation level
(maximum of 5 kHz, normal voice level, 3.0 kHz).
(11) Perform steps 9 and 10 with FM2 if applicable.
(12) Using a “Bird” type watt meter, verify antenna VSWR is less than 2.5 to 1 for all
antennas in the system.
(13) Connect antennas and verify over the air transmissions using the
communications analyzer as the other unit.
(14) Transmit using each transceiver and verify no interference with other systems on
the aircraft such as GPS, AM comms and NAV receivers.
