How do I clear a BAD FC fault?

If you are seeing the display "BAD FC" when you boot up your HI 2110WI or your HI 2151/30WC, that means the Factory Calibration has been changed and is no longer valid.

BAD FC is an error indication that something has happened to the internal calibration of the unit. If you get this error indication, the unit must be returned to the factory for evaluation/repair.
