The situation addressed by this topic is;

When doing a remote Intercom to Voice Station (Keypad) or Door Station, the voice heard on the keypad is intermiitenltly loud then soft.

This is caused by feedback from the keypad/Door Station speaker to its own microphone. Comfort tries to compensate for the echo by reducing the speaker volume when the microphone picks up too much echo.

The remedy for this is to reduce the MIC gain using the trimmer next to the Comfort main board. The Door Stations and Keypads have their own trimmer. Turn anticlockwise to reduce gain. This whould allow stable volume on both ends

The setting of the trimmer depends on telephone line conditions depending on the location of the house so the factory default adjustment may not be optimium

Cuyech will come up with a guide to getting the best results from the Intercom in the near future

When writing the tuning guide please could you remember all the places to tweak ?...

Comfort Main Board
KP Mic - VR51
DP Mic - VR53

Comfigurator
Phone Voice Level
Phone Intercom Level

Door Station
VR1A

Door Module
Mic - VR1
Voice - VR2

With so many places to make adjustments it would also be handy to know how they interact and what they do.
