NOTE: You cannot receive faxes automatically if you have a voice mail service at the same phone number you use for fax calls. You must receive faxes manually; this means you must be available to respond in person to incoming fax calls. If you want to receive faxes automatically instead, contact your telephone company to subscribe to a distinctive ring service, or to obtain a separate phone line for faxing.

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.)

•If your computer has two phone ports, set up the device as described below.
