As Retired suggested, I followed the "Factory Reset" instructions enumerated at https://www.totaline.com/dl/STAT_SETUP_CHEAT_SHEET.pdf

Factory Reset:
Move Program switch to Set
Hold Next to enter setup
Press Next to go to step 2 (“Cy”)
Press and hold Next until all icons appear
Press and hold Next until “Fd” appears.
Press Next three times
Move the Program switch

I first suggested a factory reset to defaults when I had asked about
power surges, or lightning strikes that cause a corrupt EPROM. NOW.
Did a reset work or not?
