AUDIO PANEL AND CNS
4.6 AUDIO PANELS PREFLIGHT PROCEDURE
NOTE:
If the pilot and/or copilot are using headsets that have a high/low switch or volume control knob,
verify that the switch is in the high position and the volume control on the headsets are at maximum volume
setting. On single-pilot flights, verify that all other headsets are not connected to avoid excess noise in the
audio system.
NOTE:
Adjusting the PILOT volume control affects ICS audio that is heard in the headset for the flight crew
member that is performing the adjustment. Keep in mind that the intercom volumes on the Audio Panels
are independent of one another, but the radio volumes are not.
NOTE:
When the
MAN SQ
Key is pressed, the ICS squelch can be set manually by the pilot and copilot. If
manual squelch is set to full open (SQ annunciated and the knobs turned counterclockwise) background
noise is heard in the ICS system as well as during COM transmissions.
After powering up the G1000 System, the following steps aid in maximizing the use of the Audio Panels as well
as prevent pilot and copilot induced issues. These preflight procedures should be performed each time a pilot
boards the aircraft to insure awareness of all audio levels in the Audio Panel and radios.
