Page/Party ® Line Balance
For proper operation, the line resistance for the page and party lines should be set close to 33 ohms. The
Model LE200 provides the line balance resistors needed on the page line and five party lines. These line
balance resistors are located on the 69441-xxx board next to the page and party line terminal blocks. The
line balance resistors are adjustable or can be disabled. Several headers, shorting clips, and
potentiometers control the line balance settings.
