4.7.3 Sensitivity
The sensitivity of the call station is set using switches 5
and 6 (see table 4.7).
4.7.4 Speech filter
If switch 7 is in the ON position, a speech filter is
activated for the call station. The speech filter improves
the speech intelligibility by cutting off the lower
frequencies.
4.7.5 Termination
Switch 8 must always be in the ON position, since basic
systems contain only 1 call station.
