I've connected all the wires, everything powers up, but my MX-3 controller does not do anything, as if it has no connection with the receiver. I have then connected everything back to the rusty old receiver and it works, so it's not batteries, wires, etc. So, the question is -- is there something I must do on MX-3 in order to "pair" it with the new receiver?
Many thanks.
