VOX Threshold Control
This is a rotary knob that is used to select the VOX threshold of
the unit. See
below.
When rotated fully clockwise (cw), the threshold will be at
maximum and VOX ICS operation is disabled and ICS PTT input
is required for ICS operation.
When rotated fully counterclockwise (ccw), the threshold will be
at minimum (almost live).
To adjust the unit for
VOX
(Voice activated) use, the VOX control should be set fully ccw and then slowly rotated cw to
the point where no intercom audio can be heard. The VOX control should be adjusted for proper operation according
to the ambient noise.

an external switch.
When enabled, it will illuminate when a call is received from

within the aircraft.

: Check with your installing agency for confirmation of the operation of this annunciator. The legends
are interchangeable to allow customization.
