The foot switchs appear to do nothing, tried clossing them at the connector, but will have to look at the continuity to the block terminals.

The hand sensor space is tight. Being IR has anyone tested them with the camera on their phone? I tried this trick (ala pinball and remote controls) but see nothing, making me wonder if they are dead. Also, with the hands free switch down will it still complain if the sensors don't work?
I did find the manual thing in the tube, but it is all block drawings and no real schematic related stuff.

Thanks!
