I have a HD Display 06058M that worked fine for over a year, but recently stopped logging Rain Records for the Week, Month and Year. It will show the 48 hour rainfall total fine, and the same total in Week, Month and Year display. As soon as 48 hours passes, the Week, Month and Year displays go back to 0.00. I have unplugged the display several times, will not fix the problem. How do I fix this?
