Richdel 512 PR controller

My Richdel controller - model 512 PR - will not let me set clock or set program. I press the "clock" and then "set time" key. time on the display does not start flashing as indicated in the operating manual. Any idea what is going on? I think there is a program that is running and sprinklers do come on. But we just moved in and would like to change the settings. When I try to change the program by pressing the "start A" and "set time" nothing changes again. Any idea what is going on? Thanks in advance.

Take the back up battery out and unplug the controller for 5 minutes.
When you plug it back in the controller should say SUN at 4:00 PM. If so you've reset the controller.
Now try to program again.
If it's not working I'd venture to say the buttons are worn out. That's a very old controller. Richdel's long gone.

Thank you.

Thank you mrfixit. I was thinking of doing the same but didn't want to lose the programming that is in place now. But I guess I should line up a sprinkler controller in case this stops working. It is old indeed 25 years :)
