Hi, I just purchased a Thomson VS 360 video sender for the bedroom TV. I can get a great picture and sound but the remote control will not work upstairs? For some reason I did not get any instructions with the unit but I have some sort of IR aerial lead with 3 small black plastic boxes wound onto the cable. Each has a piece of double sided sticky tape on the back of it. I've plugged it into the transmitter but don't know what to do with the actual lead itself. Any ideas? Many thanks.
