For the very first time ever on my Experia, I got several messages on the screen for "key out of range" when it was not keyed off at all.
It was raining very hard at the time, in case that had anything to do with it. Then I got caught up in a big hailstorm at Donner Summit today (CA I-80 7,200' 2,200m elevation). At least I was able to wait it out at the rest area, the road was full of ice!
In the past, I only got the message for one time each time the bike was turned on. Today, I got around a dozen. Enough to be a bit annoying, but I was more concerned with the hard rain at the time. Thunder/lightning/rain/hail for around a half hour. Most of the hail was when I was l already parked in the rest area, fortunately.
