Thanks for the suggestions guys. I now think the 3200s were not converted correctly. As soon as I plug them in to the mains they should show an amber standby light. There is nothing.
Also, the AC11 should "see" them and show a blue light as it does for the 3300 but it doesn't.

I'm hoping the guy who did the conversion only forgot something simple that I can deal with under supervision of my dealer. Am waiting for the dealer to respond now. Otherwise I will be stuck sending them off to M or something awful like dealing with the local M dealer, the thought of which is unpleasant.
