Connect the Modem to a Phone (Optional)
If you want to connect a phone to same line as the modem, plug it into the modem’s PHONE jack.
Important: The PHONE jack is not interchangeable with the LINE jack. Do not plug the telephone
into the LINE jack or the line cable into the PHONE jack.

Connect the Microphone

For voice mail or speakerphone applications, plug an unamplified microphone into the MIC jack on
the side of the modem. The microphone should have a stereo 1/8-inch mini plug. Do not use a
monophonic microphone.

Connect the Speakers

For speakerphone or voice mail applications, use a 1/8-inch plug male-to-male stereo patch cord to
connect the SPKR jack on the side of the modem to the LINE IN jack on your sound card. If your
sound card does not have a LINE IN jack, use its MIC jack. The stereo male-to-male patch cord can
be purchased at a local PC retail store.
If you do not have a sound card, you can plug an unamplified speaker directly into the SPKR jack.
Connect the Modem to the AC Power Outlet
The power switch is located on the right side of the modem. Make sure it is set to OFF. Plug the the
universal power supply into the PWR jack on the modem. Then plug one end of the country-specific
power supply cord into the universal power supply and the other end into a power outlet or power
strip.
Note: Use only the power supply supplied with the modem. Use of any other power supply voids the
warranty and can damage the modem.
