2Use the phone cord supplied in the box with the HP All-in-One

This special 2-wire phone cord is different from the more common 4-wire phone cords you might already have in your office. Check the end of the cord and compare it to the two types of cords shown below.

If you used a 4-wire phone cord, disconnect it, find the supplied 2-wire phone cord, and then connect the 2-wire phone cord to the port labeled 1-LINE on the back of the HP All-in-One.

If the HP All-in-One came with a 2-wire phone cord adaptor, you can use it with a 4- wire phone cord, in case the supplied 2-wire phone cord is too short. Attach the 2- wire phone cord adaptor to the port labeled 1-LINE on the back of the HP All-in-One. Attach your 4-wire phone cord to the open port on the adaptor and to the telephone wall jack. For more information on using the 2-wire phone cord adaptor, see the documentation that came with it.

For more information on setting up the HP All-in-One, see the printed documentation that came with the HP All-in-One.

Cause: You are using a phone line splitter between the 1-LINE port on the HP All- in-One and the wall.

Solution: A phone line splitter can affect the sound quality of your phone line and cause static. (A splitter is a two-cord connector that plugs into a telephone wall jack.)
