Battery Mismatch
If the Telephony Modem alternates flashing the Battery light and all other lights, the installed
battery is incompatible with the Telephony Modem. Remove the battery and install one of the
Battery Installation and Removal
(page 15).
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 Telephony Modem, then call a wiring technician for
assistance.
