by lumps in the lacrimal film or accept them to be corrected with the

Scout’s "points

editor".

Pressing  [Photo]  (2)  will  cause  the  rings  to  be  hidden.  Pressing  [Rings]  (4)  will
cause them to reappear.
The processed images can be shown with an absolute or axial color scale map   of
the curvatures by pressing [Curvature](4) or [Axial] (5) respectively.

on an acquired image

After acquiring the image, it is possible to send it to the external PC by pressing
[Accept] (6) even without having processed it. This same action can be taken by
pressing the button on the

joystick

.

If the PC is connected, begin the data transfer as shown in  Figure 7-25; if it is not
connected,  the  message  shown  in  Figure  7-26  signals  that  there is no connection
or,  more  simply,  that  the  acquisition  window

in the “Scout” software has not been

opened.
