Independent radio volume adjustments made using the MFD/PFD controls affect only the audio output for each

radio selected for adjustment.  Radio volume adjustment affects both crew positions equally for each radio that 
is adjusted.  Turning the master volume control located on either Audio Panel affects only the audio heard in the 
corresponding crew position headset.  Thus, radio volume adjustments may be overridden by each crew position 
independently using the master volume control on the Audio Panel for the respective crew position.  The master 
volume control for each Audio Panel affects all other system audio output for the pilot or copilot headset.

Verify the INTR COM Key is selected.

Verify manual squelch is set to minimum.

Turn the MSTR Knob (Master Volume Control) on both Audio Panels clockwise two full turns.  This sets the 
headset audio level to max volume (least amount of attenuation).

Adjust radio volume levels (COM, NAV, etc.) to a suitable level.

Adjust the ICS volume Knob on each Audio Panel to the desired intercom level.

Reset squelch to automatic, or adjust to the appropriate level manually. 

Once this procedure has been completed, the master volume controls on both Audio Panels may now be 

adjusted.  The flight crew can change settings, keeping in mind the notes above.
