Indicator Lights for the TM602A/B Models
The Touchstone Telephony Modem has seven LEDs to assist in troubleshooting.
Wiring Problems
If the Telephony Modem begins flashing all its lights for more than 10 seconds, this in-
dicates 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.
