4.6 AUDIO PANEL 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: 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.

Setting the Audio Panel during preflight:
1) Verify that the PILOT and COPLT Annunciators are extinguished.
2) Verify manual squelch is set to full open.
3) Turn the PILOT/PASS Knobs clockwise two full turns. This sets the intercom level to max volume (least amount
of attenuation).
4) Adjust radio volume levels (COM, NAV) to a suitable level.
5) Adjust the PILOT/PASS Knob volume to the desired intercom level.
6) Reset squelch to automatic, or adjust to the appropriate level manually.
Once this procedure has been completed, the pilot and copilot can change settings, keeping in mind the notes
above.
