Put new batterys back in. OR check to be sure you installed the batterys in the correct direction.

On most items the batteries are there to:
A: For the backlight
B: To Backup user settings.
Remove batteries, cut power to system for several minutes so any erroneous data is flushed. Install batteries, power back up.
After confirming item is operational, reprogram.
