4.6 AUDIO PANELS PREFLIGHT PROCEDURE
NOTE: When the MAN SQ Key is pressed, the flight crew is now able to set the ICS squelch manually. If
manual squelch is set to full open (SQ annunciated and the small knob turned counterclockwise) background
noise will be heard in the ICS system as well as during COM transmissions.
After powering up the G1000 system the following steps will aid the flight crew in maximizing the use of the
Audio Panels as well as prevent flight crew induced issues. These preflight procedures should be performed each
time a flight crew boards the aircraft to insure awareness of all audio levels in the Audio Panels and radios.
