Disconnected phone cable line from wall outlet and connected it to the LINE port in the Call blocker port. Then disconnected cable from the phone to the TEL port. Now can see display on the blocker screen. When phone comes in I select SPEAKER button on the phone base and then push BLOCK NOW. It seems to work OK, but NOT all the time. NOT sure why. When clocked SUCCESSFULL message and count goes up.
