2 Use the phone cord supplied in the box with the product
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
product.
If the product came with a 2-wire phone cord adapter, 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 adapter to the port labeled 1-LINE on the back of the product. Attach your
4-wire phone cord to the open port on the adapter and to the telephone wall jack. For
more information on using the 2-wire phone cord adapter, see the documentation that
came with it.
For more information on setting up the product, see the printed documentation that
came with the product.
Cause: The wrong phone cord was used to connect the product or the phone cord
was plugged into the wrong port.
