on the slide bar.

your screen. “>” means moving from wide to tele end; and “<” tele to wide.

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.
Focus window:
By default, the optimal focus is found on a full view window. You may designate a custom window
within your current eld 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 benet 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.
