There are two different ways to set the HP All-in-One 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 2-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 HP All-in-One as described below.

To set up the HP All-in-One 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 HP All-in-
One.
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 HP All-in-One.
