I would say try to program another PIC and change it.

I keep mine turned off for days and it does not loss the calibration.

Hi Harvey, Mine has held for almost a year now. It lost data after a power failure one time in the middle of tracking, but it seems to hold most of the time.

LVB Tracker with KR-5400A Controller.

EEPROM does not hold calibration after Controller is turned off for a while.

Do I have to go thru the calibration procedure every time it is turned on?

Am I missing something here?
