Becker AR6201 Installation And Operation Manual page 76

The Intercom Menu consists of two pages:
- Intercom Volume (first page),
- Intercom VOX (second page).
A short press on "IC/SQL" key provides toggling between the pages.

Intercom Volume Menu
The Active Frequency stays indicated in the top line of the display,
while "IC VOLUME" label appears in the bottom lines. Below the label "IC
VOLUME" a bar graph with numerical value is displayed.
By means of the "ROTARY ENCODER" the intercom volume can be changed from
0 to 46, 0 means minimum intercom volume, 46 means maximum intercom
volume. Intercom volume setting affects the Intercom audio signal and
Sidetone signal routed to the headphone.
Note: In installation with the second controller (see Figure 2-11),
adjustment of Intercom Volume by means of the RT6201 has no
effects. IC VOLUME can be regulated only by means of AR6201-
(X0X).
A short press on the "IC/SQL" key activates the Intercom VOX page.
- Intercom VOX Menu
The Active Frequency stays indicated in the top line of the display. On
the next two lines the label "IC VOX" and a bar graph with numerical
value are indicated.
By means of the "ROTARY ENCODER", Intercom VOX threshold can be set.
Setting -30 means VOX is most sensitive and even a very low microphone
signal already triggers the VOX threshold for Intercom operation, +10
means that VOX is less sensitive and only high microphone signals
trigger the VOX threshold for Intercom operation.
Note: At a setting for VOX threshold of -15 a convenient behaviour of
the VOX should be achieved in most aircrafts. This requires that
mike sensitivity had been correct adjusted (Installation Setup).
If the mike sensitivity is incorrect adjusted, VOX may work not
satisfying.
