Hardware Installation
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 2-27 for 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.
