AUDIO PANEL AND CNS

4.7 AUDIO PANELS PREFLIGHT PROCEDURE

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.

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.

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.
