Recovery
This option allows you to return the controller to
its factory calibration settings in the event that it
is severely out of calibration due to poor tech-
nique or unauthorized calibration. Although the
factory calibration settings are recovered, this
does not guarantee original calibration accuracy.
The Factory Calibration Recovery should be used
as a “starting point” for recalibration, should the
unit become severely out of calibration.
Factory Calibration Recovery is performed on
the INPT PAGE, menu RECC.
