•Go to the air conditionning console (upper left corner above the TO console, next to the met station) and set Fan speed to 20%
•From TopGui Engineering Menu launch FISBA
•Click on One Shot , if nothing happens the FISBA PC needs rebooting
•If all DM elements are not visible (i.e. Fringes not present on some segments) tweak by hand (if loading the latest flat was not enough) 
•Click on Iterate
•Save this flat from the Light Path page DM controls
•All DM elements should show one fringe only. Now they are all parallel but maybe not in the same plane
