■ 

Full-range scan: If selected, the auto focus scan will be performed throughout the complete 

range of focus� The full-range scan takes a longer time to complete� A full-range scan usually 

takes approximately 3 minutes or longer�

■ 

Fully-open Iris: By default, this checkbox is selected for performing an auto scan and should 

provide an optimal scan result�  

By default, the optimal focus is found on a full view window� You may designate a custom window 

within your current field of view to acquire the best focus out of it. However, you can not place a 

focus window on a distant background, e�g�, a hall way that stretches away for 3 meters or farther� 

Doing so you will not benefit from the Focus window function. 

■ 

Full view: The focus tuning takes place by referring to the full view. 

■ 

Custom: You can create a focus window and drag it to a place of interest in your view window. 

Note that it is recommended to use this function only when you have a solid object in your view 

window that is showing a consistent color or texture� This function will not take effect if you set 

the focus window on a distant background�
