on the display on the right upper corner, it shows the messages, which cycle through the different things like highest temp, highest wind, etc. If it rains, the message center changes to todays rainfall and will not revert back to the cycling messages. My fix for this is to unplug the display and plug it back in, this resets the message portion and it goes back to cycling thru the different recordings.....until it rains again and then you have to unplug again. Something is wrong in the programming for sure. Another thing is in the cycling messages, one says "warmest day this weeK", however, it does not show the day or date, just warmest day this week. Another error in the programming of these units is the "24 hour temperature change" it always shows "0", not the actual temp change. By the way, unplugging the display and then plugging it back in does not lose any of the recorded data. I suppose if you fiddled around for 5 minutes, it probably would??? but, I just do it within about 5 seconds.
