When the edging cycle is finished, remove the edged lens without removing the block so as to be able to
retouch it if necessary.

screen. During the cycle, when the manual finishing screen is displayed, press the Manual Bevel button,
select the type of bevel you wish and visualise the position of the bevel apex directly on the screen.
