2.3.6.2 Power On Checks
Install the AA24 or AA25 and power up the ship’s systems. Verify normal operation of all functions.
Refer to Section 3 for specific operation details.
a) Run through all installed functions, and check the ICS and TX functions for all users.
b) Different headsets models may have significantly different mic characteristics, which will affect
‘VOX’ squelch settings. The David Clark M-7 mic is much more active than the M-4 or M-1 mics,
and may aggravate headset imbalance if used in a mixed system.
Note: Unusual buzzes, hums or other background audio are symptomatic of multiple grounds, or
noisy external systems such as blowers or pumps sharing wiring with the audio system. Failure
to key or correctly modulate a transmitter is often the result of forgetting to connect all required
grounds to the radio or external audio system.
c) To verify proper operation, all functions and levels should be checked in-flight.
If the unit functions satisfactory, make the required log entries and complete the required
MOT/FAA paperwork, before releasing the aircraft for service.
