it.

set:

distance 20cm).
ICON OFF: indicates that the external removable rectangular or round cone is attached to the x-ray device
(source-skin distance 30cm).
Refer to paragraph 5.3 to set the type of movable collimator used.
NOTE: After the rectangular collimator (12”) has been attached or detached, the icon and set exposure
times will automatically be modified within a few seconds.
