Setting Switch SW1.1

The first switch (SW1.1) controls the line impedance. The settings should all be set to the OPEN position initially (as shown in Figure 2-27for each configuration). If problems are encountered with Touch-Tone recognition, change all of the switches on the first bank (SW1.1) to the opposite (closed)position.
