As I haven't got the Nano (display too small for my old eyes), this is what Pietro to told me when he was describing it to me. I will also ask him today to provide a video of it in action. Plus Pietro when telling me about it a while ago that it worked like the Novag Citrine.

Nano commands.

To start a new game.
Place all the pieces in their initial position then place the spare queen on a3 then remove it and then make your first move.

To set up a position.
Set up the pieces and then finally the two kings then it will start automatically.

It also has a training mode. You lift a piece will run variational analysis giving you CP evaluation of position.
