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.
