I have exactly the same issue. I have unplugged it, hit the reset button for 3 seconds. Then powered it up. Made the adjustments to time, etc. There were three options flashing by the rainfall display. 24 hr, weekly and monthly, but there's no way to change that, only the measurement from inch to mm. When the display finishes with the settings, the rainfall readout goes back to week and year. I want 24 hour and weekly on the second line. Am I doing something wrong? Can't seem to make any sense out of the display instruction book. Thanks
