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 if
you are using your computer dial-up modem to send an e-mail or access the Internet.
There are two different ways to set up 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.)
Example of a parallel splitter
• If your computer has two phone ports, set up the device as described below.

To set up the device on the same phone line as a computer with two phone ports
1. Remove the white plug from the port labeled 2-EXT on the back of the device.
2. Find the phone cord that connects from the back of your computer (your computer dial-up
modem) to a telephone wall jack. Disconnect the cord from the telephone wall jack and plug it
into the port labeled 2-EXT on the back of the device.
3. Connect a phone to the "OUT" port on the back of your computer dial-up modem.
