I have an RD-1200 Rain Dial that has a frozen display and controls. The display shows a time of 2 AM but it can't be changed and none of the other controls or programs respond. The Rain Dial is getting AC power and I put in a new 9 V battery but that hasn't done anything. Obviously my sprinklers aren't working. We did have a power outage last Monday but it didn't occur at 2 AM. How do I fix the problem?
