Operating Manual
Page 5
This is a customizable dead-front
annunciator activated by an external
switch.
When enabled, it will illuminate when
a ground is applied to the CALL input
from another user’s audio controller
or by a remote ‘call’ button within the
aircraft.
This is a rotary knob 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).
This is a customizable legend to
mark the PA position for the
transmit selector.
The interchangeability allows an
appropriate name for this legend
to be selected.
Note
: Check with your installing agency for confirmation of the
operation of this annunciator. The legends are interchangeable
to allow customization.
