Receiver uses 4 C batteries and can work wired to the control box or wireless as a receiver. One of the three level green LED does not light up. The picture shows two LED lit. Plastic exterior colored film does show signs of use.
None of this affects the operation. The CB24+ control box is untested. The 4 pin connector should be for source power.At first I thought the threads were notched but now I think part has broken off. I have NO cables to check.
I will guess that if the receiver works the control box will when connected with the right cables by a trained professional.
