2.3.6 Post-Installation Checks

If any preset requires adjustment, be sure this is carried out before the aircraft leaves, and that the unit

and its mating connector are secured before departure. Make all required log book entries, electrical

load, weight and balance amendments and other paperwork as required by your local regulatory agency.

2.3.6.1 Voltage/resistance checks

Do not attach the AA83-100 until the following conditions are met.

Check the following:

a) Check P101, pin <1> for +12 to +28 Vdc relative to ground.

b) Check P101, pin <16> for continuity to ground (less than 0.5 :).

c) Check P101, pins <11> and <12> for continuity to ground (less than 0.5 :) when the relevant ICS

switch is keyed.

d) Check all mic, phone, music, and key lines for shorts to ground or adjacent pins. Check all key

lines for correct operation.

2.3.6.2 Power On checks

Install the AA83-100 and power up the aircraft’s systems, and turn on the radios and accessories

required. Verify normal operation of all functions. Refer to Section 3 for specific operation details.

a) Begin with only the pilot's headset installed, no hand mic. Check for correct radio operation (both

receive and transmit) and ICS operation. Check yoke (or cyclic) switch action.

b) If there is a music source in the system turn it on and verify that music is heard in all modes

except PLT ISO. Check for proper mute operation.

Note: Unusual buzzes, hums or other background audio may be symptomatic of multiple grounds or

noisy external systems sharing the same wire bundle. Incorrect jack wiring is a common fault,

especially for passenger stations, and may cause loss of audio, a tone on the headset lines, or
