Do that for each program and then power the controller down, pull the battery and let it sit for a good 15 minutes and then power it back up and re-program.
I thought it was the MC Plus-B that had the NVM.
I may be wrong. Found a 1997 MC Plus manual online that says it has a NVM and a 9 V alkaline for current time.
All I can figure is that the one on one of my jobs with the NiCad batteries must be an earlier version.
