One telephone line card is installed in the receiver
when shipped from the factory.
3. Slide a line card into the slot next to the installed
line card.
4. Remove the appropriate snap-in covers from the
front of the panel.
5. Close the front panel.

printer report), the settings in the line card
programming section automatically load into the
card.

4.1.3 Telephone Line Monitoring Voltage
The receiver continuously monitors the telephone line
voltage. Normal operating voltage ranges from
1.8 VDC to 2.5 VDC. Any voltage above 2.5 VDC
causes the line to appear good (restoral) and an
indication appears if any voltage is below 1.8 VDC.
