NOTE: Since your computer dial-up modem shares the phone line with the

device, you cannot use both your modem and the device simultaneously. For

example, you cannot use the device for faxing while you are using your computer

dial-up modem to send an e-mail or access the Internet.

There are two different ways to set the device with your computer based on the

number of phone ports on your computer. Before you begin, check your computer to

see if it has one or two phone ports.

• If your computer has only one phone port, you will need to purchase a parallel

splitter (also called a coupler), as shown below. (A parallel splitter has one RJ-11

port on the front and two RJ-11 ports on the back. Do not use a two-line phone

splitter, a serial splitter, or a parallel splitter which has two RJ-11 ports on the front

and a plug on the back.)

• If your computer has one phone port, set up the device as described below.
