2.4.4 VOX - Voice Activation Speech Level for the Intercom
By short pressing the
key three times, with the help of the
rotary knob, the threshold value for VOX can be adjusted.
VOX defines the crew’s speech volume that is required to activate the
intercom functionality. The higher the value, the louder you need to
speak in order to activate the intercom.
Exception: VOX 01 corresponds to “always on”
The internal filter circuitry has the ability to distinguish between engine
noise and speech.

VOX 05
In case of very noisy backgrounds or use of uncompensated
microphones, the automatically VOX functionality may not work
satisfying. In these cases, it is possible to deactivate the VOX
automatism with VOX 01, and to use an external intercom-switch.
The default Squelch setting is SQ05 (up to SW V5.7: SQ07).
High values can suppress weak signals. Squelch is not
related to any function of the Intercom.
