Maybe we need to get the geek squad (i.e., X) to get to the bottom of this.
If I hold the button for 10 seconds, is the setting I see the one that it was or the one it just became? If it is the one it just became, then when I did mine (it was reading NO 1), I was actually on NO 2 like I thought. I'm too lazy/busy to figure it out now.
If you hold the + button and it shows, for instance, NO 1, it means you were previously set at NO 2 and have now changed it to NO 1. The 10 second hold is a toggle, not a check.
