ICS Volume Control
The inner knob of the left hand dual control is ICS VOL and controls the intercom
volume for all headsets. An internal trimpot sets the minimum level. With ICS VOL set
fully ccw intercom volume will be at a minimum. As the operator rotates the control cw,
intercom volume will increase.
3.3.3.2
Music Volume Control
The inner knob of the right hand dual control is MUSIC VOL and controls the music
volume for all headsets. With MUSIC VOL fully ccw music volume will be at a minimum.
As the operator rotates the control cw, music volume will increase.
CAUTION
The AA85 has no front panel radio volume control. Take
care when adjusting aircraft radios as low radio volume may
affect the AA85 mute functions.

The TX/ICS indicator is a dual color LED that will illuminate green during radio transmit
operations and amber during ICS operations.
3.3.5 ICS Mute Functions

In ALL mode, intercom audio will mute at all positions whenever the pilot or copilot
‘Keys’ the radio.

PLT ISO

‘Keys’ the radio, but will mute when the copilot ‘Keys’ the radio. The pilot has no
connection to any intercom or music functions, and therefore requires no mute.
