2.4.4 VOX – Voice Detection (Speech Threshold for Voice
Activated Intercom)
By shortly pressing the
SET
key three times, with the help of the
rotary knob, the threshold volume VOX for intercom voice
detection can be adjusted. (Note: This is not related in any way to radio
reception or squelch.)
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 automatic VOX functionality may not work satisfyingly.
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 05. At higher values, weak
signals could be suppressed.
