Setting the Microphone Levels
On the Comfort CPU, VR1 sets the MIC recording and listening level for
the Microphone. Adjust this trimmer when in two way Voice Station
Mode between a telephone or mobile phone and keypad or Doorphone
rather than between two keypads to so that any feedback may be
adjusted out. This is normally set at about 50%. In practice the volume
of the internal speaker volume within the doorphone need only be
slightly off zero. While in Doorphone menu between a telephone and a
Doorphone (kept at least 4 metres apart), turn the pot fully clockwise
and then slowly turn it anti-clockwise at the same time being aware of
the start of feedback. The correct level would be about 2-3mm off hard
right.
