I've bought a Chinese knockoff Servonaut sound board from wbtcar (Lesu, I think). No instructions came with it, just a wiring diagram. I've got it wired in to the truck as shown, the green light on the board lights up, but no sound.

While installing it, I noticed a programming plug labeled "remove for set up", so I tried that way, but still no sound.

Does anyone know the setup procedure for these boards? HELP!
