Got a nice endless loop going. 1040 can't find my Bontrager headlight, and gives a perpetual sensor disconnected alert (both visual and highly-annoying beep). And screen input is USELESS because nothing can get past the sensor disconnect prompt. You click it and there's another one with no chance to hit anything else on the screen. You can't even turn it off. Hit the power button and you'll change to the relevant screen, but you still can't get past the sensor disconnect alert, which requires you to click it to make it go away, after which another one appears... over and over and over.
Finally got past it by holding down all three buttons. It rebooted and came back up without the sensor warning. In fact, it even appears to have deleted offending sensor. h
