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.
