Indicator Lights for the TM502G/H Models
The Touchstone Telephony Modem has eight indicator lights to assist in troubleshooting. Note that
not all models have a Battery light.
Wiring Problems
If the Telephony Modem begins flashing all its lights for more than 10 seconds, this indicates a prob-
lem 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.
