The switches in the modem selects whether the modem operates on Com 1, 2,
3, or 4.  If the computer is not using another serial device, such as a 
serial mouse or printer, that is currently set on Com 2, leave the modem
on the factory default setting of Com 2.  Otherwise, set the modem to
Com 1, Com 3, or Com 4.

INSTALLING THE MODEM IN THE COMPUTER


Before you install any boards in the computer, be sure to disconnect all
power and interface cables from the computer and move the computer to a
static-free work area.  Then discharge any static buildup by touching a
grounded metal object.  Never power the computer when you have removed its
case or when you insert or remove option boards.

1.  Remove the screws that secure the computer's case and slide off the
    cover to open the computer.  Consult your computer owner's manual for
    details.  Save these screws.

2.  Select the expansion slot into which you want to install the modem.
    The modem card fits in either half- or full-card slots.

3.  Remove the slot cover on the back of the computer case by removing its
    holding screw and lifting out the cover.

4.  Press the modem into the expansion slot.  Secure the modem using the
    same screw you removed in Step 3.

5.  Replace the computer case and secure it with the same screws you 
    removed in Step 1.

6.  Connect all interface cables for other peripherals.  Then reconnect
    the computer's power cable.

7.  Connect one end of the modular phone cable to the modem's LINE jack on
    the back of the modem.

8.  Connect the other end of the modular phone cable to a modular
    telephone jack.

NOTES:  You can connect a standard telephone to the modem's PHONE jack on
        the back of the modem.  We provided this jack for your convenience
        so you can continue to use the telephone normally.  As long as you
        leave the modem and telephone connected, you can continue to use
        the telephone, even when you turn off the computer.

        The telephone company can charge you for the installation of
        necessary jacks.  The telephone company will ask you the U.S.O.C.
        number of the jack to be installed.  This number is RJ11C.
