Wiring Problems

If the Telephony Modem begins flashing all its lights for more than 10 seconds, this

indicates a problem with the telephone wiring — the red and green wires may be

shorted (touching), or there may be undesired voltage on the lines. If this pattern

persists for more than 10 seconds, disconnect the telephone lines from the Tele-

phony Modem, then call a wiring technician for assistance.
