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 with
ambient noise.

CALL Annunciator
This is a deadfront annunciator.
When enabled, it will illuminate when a ground is applied to
the CALL input from another user’s audio controller or by an
external ‘call’ button.
The default legend is 'CALL', but it is interchangeable to
allow customization.
Note
:
Check with your installing agency for confirmation of the operation of this annunciator. The legends
are interchangeable to allow customization.

ICS Volume Control
This is a rotary control used to adjust the
volume of all ICS audio to suit the ambient
conditions. Rotating the control completely
cw gives rated level, and completely ccw
reduces the output to minimum level.
