Internal Modem Installation with Windows 3.x

7.Once the modem is inserted, fasten it firmly into place using the screw that you removed in step 5.

8.Replace the computer’s cover and fasten it with the screws you removed in step 4.

9.Locate the phone wall socket you plan to use for the modem. If you have a phone plugged into this wall socket, disconnect the telephone cord from the socket.

The phone wall socket you use must be for an ANALOGUE phone line (the type found in most homes). Many office buildings have digital phone lines. Be sure you know which type of line you have. The modem will be damaged if you use a digital phone line.

10.Plug one end of the phone cord included with the modem into the TELCO socket.

11.Plug the other end of the cable into the phone wall socket.

You cannot use the modem and a phone at the same time if they share the same telephone line. If you want to use a telephone on the same line as the modem when the modem is not in use, plug your telephone cord into the modem’s PHONE socket, using the supplied Tail Lead Adaptor.

12.An external, powered speaker must be connected for speakerphone and voice mail usage. Plug a set of powered, magnetically-shielded, external speakers or a headset (not included) into the 3.5 mm SPKR socket on the modem.

12.13. Plug the supplied microphone into the 3.5 mm MIC socket on the modem.
