Ideally, I would like to route thru the cable box. On the camera base, I made sure that it was set on A. Also made sure that the electric supply unit was set to A1. Using the modulator, I connected the yellow/white wires to their respective connections on both the receiver and the modulator. On the modulator, I set the front switch to channel 3. Next, I installed a coax cable from the "TO TV" side to the television. The second cable goes from "ANT IN" to the camera receiver. When I change to video on the TV, I get a message to "Connect the A/V" jacks. Once again, I must be missing something.
