NOTE:
Following any calibration procedure that has calibration values stored in the
Cal/Config Data, storage of the new values must be verified by cycling the power off-on
before you perform final system checkout
. If values obtained by the HFA II - i during
calibration are not within an expected range, those values are held only in temporary
storage and not written to the Cal/Config Data. When power is turned off, these values
are erased and calibration reverts to its old status.
