In the case of very noisy backgrounds, or use of uncompensated
microphones, the automatic VOX functionality may not work adequately.
In these cases, it is possible to deactivate the VOX automatics with VOX:
0 = off, and to use an external intercom-switch instead.
2.5.4 INT
– Intercom Volume
By pressing the SET button three times, the volume of the intercom can
be adjusted with the VOL/SEL turn knob.
The intercom function is the on-board crew-internal communication for
multi-seater aircraft.
A change in the intercom volume level also changes the volume of the
sidetone. The sidetone is an audible feedback of ones`s own voice to the
headset, i.e. you hear yourself speak. This feature supports natural
speech behaviour.
The intercom can be activated in two ways:
Automatically, i.e. whenever someone speaks into a microphone
(i.e. voice activated intercom = VOX, see § 2.5.3).
Manually, i.e. by use of an external intercom switch.
Range 0 - 20
2.5.5 STL
– Volume Sidetone Left
The sidetone is a self-hearing or back-hearing function during
transmission and intercom. The audio signal picked up by the
microphone is fed directly to the headset, which sounds natural. In this
menu the volume of the sidetone for the left seat can be adjusted.
If the intercom is deactivated by the wiring set-up, the
intercom volume cannot be adjusted.
