2.4.5 DWM – Dual Watch Volume Reduction
By shortly pressing the
SET
key four times, with help from the
rotary knob the lowering of the volume level (“mute”) for
receptions on the standby frequency (when having dual watch active)
can be controlled. This allows acoustic distinction between both
frequencies.
For further information about the dual watch mode see 2.6.

2.4.6 INT - Intercom-Volume
The intercom functionality is the onboard crew-internal communication
for multiseater aircraft.
By shortly pressing the
SET
key five times, the intercom volume level
can be controlled by the
rotary knob. The higher the value, the
higher the intercom volume.
A change in the intercom volume level also changes the volume of the
sidetone. The sidetone is an audible feedback of the own voice to the
headset, i.e. you hear yourself speak. This feature supports a 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 2.4.4).
•
Manually, i.e. by use of an external intercom switch (cable overview
see 4.7.3.1).
