Q. I tried to turn my neighbor's TV on and it didn't work. How come?
A. Because your TV-B-Gone® remote control works by infra-red light (IR), it won't go through ceilings, walls or some glass. It also has to be aimed within 30 degrees at the remote control receptor on the front of the TV, and so you must be able to face the TV or just be slightly to the side of it.
