INSTALLATION ON A PC-COMPATIBLE

PRELIMINARY PROCEDURES

1)  WARNING:  TURN OFF ALL EQUIPMENT.  If any unit is on, you can damage
the central processing unit or the board.  Wait at least 10 seconds before
removing or inserting any board into the computer.

2)  To avoid static electricity buildup, which can destroy certain
integrated circuits, touch a grounded metal object before handling any
circuit board. Do not stand on a carpeted floor while installing this board.

3)  Remove the 2 screws on the front of the main unit.  Remove the cover by
sliding it away from the rear of the unit, parallel to the computer.

4)  Before installing the PC Modem, set the four options switches to meet
your installation requirements.

1200 BAUD PC MODEM

1)  To install the PC Modem, rotate the chassis so that the back of the
computer faces you. Select any empty socket as the location for the
PC-Modem. It makes no difference which you use.

2)  Remove the sheet-metal screw from the top of the selected cover.  Tilt
the metal strip away from you and lift the strip so the tab on the panel 
clears the bottom of the slot.  Store the cover in a safe place for future 
replacement.

3)  Discharge any static buildup by touching a grounded metal object.  Now
grasp the PC Modem by its upper edges and position it above the black 
edge-connector socket.  Insert the lower tab on the board's mounting 
bracket into the slot on the rear of the chassis, in the same way the 
option slot covers are mounted.  At the same time, apply even downward 
pressure engaging the edge-connector into its socket.  Align the entire 
card so that the U-shaped cutout on the top of the option card is 
positioned over the screw-hole on the rear of the chassis.  Replace the 
screw you removed before and tighten it to secure the board.  Do not 
overtighten the screw.

4)  Replace the top cover, securing it with the screws previously removed.

5)  There are two modular phone connectors on the rear panel of the PC
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.  The PC 
Modem is now ready for use.

    Note:  The second jack on the back of the PC 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 PC Modem can be left connected even when your computer is turned off.
It will not affect the normal use of your phone.
