Connect the Phone to the Modem (Optional)
For voice-only calls, plug a telephone into the modem’s PHONE jack.
Connect the Modem to the AC Power Outlet
Plug the power transformer into an AC power outlet or power strip. Plug the power transformer’s
cable into the POWER jack on the modem.
Note: Use only the power transformer supplied with the modem. Use of any other transformer voids
the warranty and can damage the modem.
Power-On Test
Test the modem by turning it on (a power switch is located on the front panel). When you apply
power, the modem performs a diagnostic self-test, indicated by the TM indicator lighting for a few
seconds, after which the LCD should light. If this does not happen, check that the power switch is
on, the power transformer is solidly connected, and the AC outlet is live. If these measures do not
work, see the “Troubleshooting” chapter.
