Was pushing the blue ring buttons to find a combination that would turn off the LED's and found that if I hold down the left LED button then press the right one, the LED went off! Tried the same for up arrow and down arrow and they went out also! Just have to figure out how to get the left one off. So now all I have is a "new moon" showing. That helps quite a bit. I was in the main menu when I did this.. There is always a "back door" for hidden diagnostics and key strokes for "Tech Support" gurus left by programmer's. If I find the magic key stroke(S) needed to extinguish the last LED, will post it. If anyone discovers it, please post.
