Calibrating the Balanced Line
This procedure is carried out on the analog line if the reciter network board has
been replaced or repaired. It adjusts the gain, so that when you set line levels
using the CSS, the actual line level correctly reflects the CSS settings. (Refer to
the TB9100 Customer Service Software User’s Manual for further information.)
