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.
