I originally posted this for a few friends inquiring about the RTC Clock on the controller losing its time. Well, the solution is to replace the battery. Here is a snippet of my post
“2504 does contain a battery CR2032. Here is a fresh shot of a controller naked. Good thing I opened up mine as the RAM was partially ejected on one side.
Use a proper CR2032 Energizer / Duracell. Not your dollar store variety. ”
