[Elecraft] KX3 - EEINIT - Calibration Information

[David Patino]

Does performing an EEINIT on the KX3 erase calibration information, mainly the Receive Sideband calibration for use with the roofing filter?
 
In the documentation it recommends writing down the settings when you do it yourself for future reference, but by any chance does the factory keep records of these when they do the calibration on assembled units?
 
Thanks
