Installation Guide) shall be performed before the back focus adjustment.
<Back focus adjustment>
The back focus adjustment is performed by changing the distance between the lens and focal point.
Follow the procedure below.
Important:
• The auto back focus function is used for back focus adjustment at installation and for focus correction at switching between the
color and black-and-white modes after installation. This function is not a function that is supposed to be operated continuously
such as the auto focus function.
• When focus missing occurs due to secular change in the lens and installation environment or peripheral temperature change, the
back focus adjustment is required again.
Note:
• The back focus adjustment can be also performed through the operation buttons. (

PRESET: Performs the preset movement to each specified back focus position when switching between color and black-and-white
images. The preset position is the back focus position specified last time, which was automatically memorized for each of color
images and black-and-white images.
FIX: Fixes the position after adjusting the back focus either automatically (ABF) or manually.
