The Casio FX-850P calculator may not work after replacing all batteries at once because it enters an error state when all three batteries are removed or replaced simultaneously. To avoid this, the batteries must be replaced in two steps: first replace the two CR-2032 batteries, then the one CR-1220 battery. Replacing all at once can cause memory loss or system errors, such as failure to perform basic calculations or run programs.
