idroba thanks for your explanation. it was extremely helpful. As was at Blue yesterday and had a change to play with the S/U switch and see the effect on the " press for 2 seconds for all dark" display. I suspect that when camping w/ SP, that as long is stay on the Use, that function and the demo will still be as I programmed them. I think it's going to store while on SP that may be triggering the reset.
Peter, thanks too for your confirmation and feedback on you unit. I'm sure there is symmetry to a great extent here.
Thanks again for all you help, info and insight.
