5. Before handling the MultiModem, discharge static in your body by touching a piece of bare metal on
the chassis. Carefully remove the MultiModem from its antistatic bag, handling it only by the
mounting bracket and edges. Do not touch the gold-plated connectors along the bottom edge.
6. Look at the system's main board to determine either PCI or Express connector. Place the
MultiModem directly above the expansion slot and gently, but firmly, push it into the connector until
the card's retaining bracket is flush against the system chassis.
8. Fasten the retaining bracket to the system chassis with the screw saved in step 4.
9. Replace the system cover.

Make the External Connections

Now connect the MultiModem to the telephone line and, optionally, to your telephone. For voice mail or
speakerphone use, you can also connect it to a microphone and an external speaker, headphone, or sound
card. The microphone can be used for recording answering machine messages or for speakerphone use.
The speaker or headphone can be used for playing back messages or as a speakerphone.

Line Connection

Plug one end of the provided telephone cable into the modem's LINE jack, and the other end into a
telephone wall jack. This is the only required connection.
Note: The LINE jack is not interchangeable with the PHONE jack. Do not plug the phone into the LINE jack
or the line cable into the PHONE jack.
Note: The Federal Communications Commission (FCC) and Industry Canada impose certain restrictions on
equipment connected to public telephone systems.

Phone Connection (Optional)

If you wish to connect a telephone to the same line as the modem, plug it into the modem's PHONE jack.
Note: The PHONE jack is not interchangeable with the LINE jack. Do not plug the phone into the LINE jack
or the line cable into the PHONE jack.

Microphone/Headphone Connection (Optional)

For voice mail or speakerphone applications, plug an unamplified microphone into the MIC jack. The
microphone and headphone should have a stereo 3.58mm (9/64-inch) mini plug. Do not use a monophonic
microphone.

Sound Card and Speaker Connections (If you have the Voice Option)

For voice mail or speakerphone applications, use a 3.58mm (9/64-inch) plug male-to-male stereo patch cord
to connect the LINE OUT jack on 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.
This will allow you to hear modem activity whether it is originating or answering a call, or playing a recorded
message. If you do not have a sound card, you can plug an amplified speaker into the LINE OUT jack.
