Power On Checks
Power up the audio system with the AA31 installed. Verify that the ISO (amber) and COMMON (green)
LEDs light as the ICS Function Knob is rotated from the ALL COMMON position to the isolated positions.
Verify that the ICS Function Outputs are correctly driving their external annunciators, if installed.
Ensure that the REAR CALL annunciators on the front panel of the AA31 are operating correctly if
external switches for this function are installed.
Check that turning on the panel lights will backlight the AA31 faceplate and will dim the faceplate
annunciators.
Verify that ICS Audio is being switched between Audio Controllers as the ICS Function Knob is rotated.
Ensure that the ICS Audio level is consistent at each Audio Controller as the ICS function knob is rotated.
Upon satisfactory completion of all performance checks, make the required log entries and
complete the necessary Regulatory Agency paperwork before releasing the aircraft for service.
