5.9 Using the camera install menu
Five keys, located behind the side door panel, are used for
accessing the camera menu.
To open the install menu press and hold the center key for
approximately two seconds. The BNC video output is activated
and the Install menu appears on the monitor.
5.10 Back focus adjustment
To optimize picture sharpness in both bright and low-level
lighting, adjust the back focus. Use the camera's unique Lens
Wizard. This ensures that the object of interest always remains
in focus, even when focusing at the maximum lens iris opening
(for example, at night).
– When back focusing varifocal lenses, adjust to obtain a
sharp picture in both wide-angle and tele positions for
both far and near focus.
– When back focusing zoom lenses, ensure the object of
interest remains in focus throughout the entire zoom range
of the lens.
To adjust back focus:
1. Slide open the door panel at the side of the camera.
2. Unlock the back focus locking button.
