3.3.3 CHECKING A FINISHING BEFORE THE LENS IS EDGED
3.3.3.1 PRINCIPLE
 You may wish to check the position of the desired finishing - bevel and groove - before beginning the lens
edging cycle.
 You may also wish to position the finishing yourself when running a job.
 You may be automatically redirected to this screen.
Example : The desired finishing position cannot be applied to the lens being edged.
A special screen allows you to visualise the finishing and modify its position, if desired.
IMPORTANT NOTE
The indices of zones A and B indicate the same finishing angular position. When you move one, the other moves
as well.
