1200 BPS Internal Modem (250-3510)      Install        Faxback Doc. # 4763

To Install:

1)  Remove the slot cover over the "Modem Option" slot on the back of the
    computer.  It is held in place by two small screws.

2)  Gently slide in the modem as illustrated.  Press in to ensure that it
    is seated securely in the connector.  Use the screws that held the
     cover to secure the modem into the computer.

3)  There are two modular phone connectors on the rear panel of the Tandy
    1200 bps internal modem.  Connect one end of the modular phone cable
    supplied with the modem into either of these two jacks.  These jacks
    are identical; it does not matter which one you use.  Connect the other
    end of this modular cable into your wall jack.

>>     NOTE:  The second jack on the back of the modem can be used to
       connect your standard telephone.  This is provided for your
       convenience.  You may plug your telephone into this jack and
       continue to use it normally. The modem can be left connected even
       when your computer is turned off.  It will not affect the normal
       use of your telephone.

4)  If you will be using the Tandy Acoustic Coupler, insert the connector
    into the holes marked Acoustic Coupler.  There is only one way to
    insert the connector.

5)  You are now ready to initialize the modem.  Begin from the DOS prompt
    "A:" While holding down the CTRL and ALT keys, press the INS key. This
    will bring up the Tandy 1400 LT Set Up Menu.

6)  Press the F4 key to highlight the RS232C / Internal Modem option.
    Press the right arrow key to highlight MODEM.  Press ENTER.

7)  Press the F5 key to highlight the Direct Modem / Acoustic Coupler option.
    Press the arrow keys to highlight DIRECT if you will be connecting the
    modem directly to the phone line or to ACOUST if you will be using the
    Acoustic Coupler.  Press ENTER and then escape to return to DOS.

8)  You are now ready to use the modem. Note that you do not need to reini-
    tialize each time you use the modem. However, each time you switch
    between direct use and the acoustic coupler, you will need to
    reinitialize, following steps 5-7.
