69 69  Since there may be a somewhat different setting needed for the ROIs for BL and PG there is the option (in the expert settings) to set the ROIs different fror PG and BL. The move buttons also set the according ROIs ( moving to BL sets the BL ROIs...). It is also checked that the correct ROI is set when moving the screen . A warning is displayed if the ROI is not the same as in the reference values.
