need to be wary of "bumping" any of the buttons...
If you go back up to reply #4 with my photo of the control panel, you can see a rigid brown "ledge" below the cycle buttons. When I saw that last night I thought "Hmm, that's odd", but now it makes perfect sense. That ledge below the buttons is there to help prevent the buttons getting pressed if you bump it.
I wonder if this"stacks the cycles", like programming a juke box. If you press more then one button, will it "play" each cycle you press, one after the other?
