Internal Modem Installation with Windows 95

4.When doing a “Plug and Play” installation, the jumper shunts should be placed so that they are hanging from single jumper pins rather than on pairs of pins. Move your jumper shunts so they are hanging as in the diagram.

If you need to move the jumper shunts, grasp them with tweezers or needle-nosed pliers. DO NOT grasp too firmly, however, or you may crush the jumper shunts. If a jumper shunt seems stuck, try gently rocking it back and forth as you lift.

How to Insert the Modem into the Computer

1.Before installing your modem, write down your modem's serial number. The serial number is on the white label under the bar code on the modem and on the outside of the box.

Serial Number_______________________

Before you unplug any cords, label them or make a sketch of how they are connected. This can be helpful when you plug them back in later.

2.Turn off your computer and unplug it from the electrical outlet.

2.3.Unplug any peripheral devices (printer, monitor, keyboard, mouse, etc.) from the computer.

CAUTION: To avoid risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged from electrical outlets.
