Arris Touchstone TM804 - Wiring Problems; Battery Mismatch; Patterns: Normal Operation

Chapter 6: Operate the Telephony Modem
8. US: indicates upstream connectivity.
9. DS: indicates downstream connectivity.
10. Power: Indicates whether power is available to the device.
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.
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 batteries described in Install and replace the battery (TM804G only) (page 17).
