Line Settings
A separate Automatic Gain Control (AGC) can be switched on for both

lect Off. To switch it on select On.
FIG. 25 CONFIGURATION AGC
Via the button Set AGC on/off for all lines you can switch on respectively
switch off the AGC for all lines.
•An Expander tones down the caller signal automatically, if its level falls
below a certain threshold value. The aim is to completely filter out back-
ground noises of callers who are not currently speaking.
ATTENTION An Automatic Gain Control is reasonable if you do not have the possibility
for Pretalk during which the level can be adjusted.
But: An AGC is no wizard. Extremely low callers cannot be boosted bound-
lessly. Extremely loud callers cannot be toned down boundlessly.
