You must use a wall electric outlet for both units and not a surge protector strip.
Basically you plug in the wireless receiver to a electrical outlet near an existing phone jack - run a regular phone line plug between the wireless receiver and the existing phone jack. (there is a second phone plug on the wireless receiver that allows you to plug in a phone since you have now taken up the existing phone jack)
Then take your wireless phone outlet and plug it into a electrical wall outlet where you need it (near your TIVO) and plug in a regular phone line between the wireless phone outlet and your Tivo.
Also once you have one wireless receiver you can add several more wireless phone outlet units off one receiver. Typically you get one wireless receiver and one wireless phone outlet with the original purchased set but you can add more wireless phone outlets if you like.
Got it. We’re all set with the electric plugs.
