Adjusting field angle, focus and

brightness

Once you have decided the shooting direction,

you can adjust the field angle, focus and

brightness.

Note：

● Be sure to hold the dome cover over the lens

when adjusting the focus. The dome cover is

made thicker for performance purposes. If

focus is not adjusted with the dome cover

held over the lens, the camera may be out of

focus when the dome cover is actually

attached.

● When adjusting focus, hold the dome cover

over the lens such that the optical axis of the

lens and the center of the dome cover is

perpendicular to each other and the image is

not distorted. (Refer to the diagram below)

Field angle adjustment

Loosen the fastening screw of the zoom

adjustment ring, move the ring left and right and

adjust the image size.

Focus adjustment

Press the focus adjustment button. The Iris will

open for approximately 30 seconds. Loosen the

fastening screw of the focus adjustment ring,

move the ring left and right and adjust the focus.

Memo：

● Repeat “Field angle adjustment” and “Focus

adjustment” two to three times to adjust the

settings.

After adjustment is complete, tighten and

secure the respective fastening screws.

● Pressing the focus adjustment button

automatically activates the electronic shutter.

The screen may flicker but this is not a

malfunction.

Note：

● Do not adjust the iris level within 30 seconds

after pressing the focus adjustment button.

The electronic shutter will activate and you

will not be able to adjust correctly.

● When adjusting the iris level, set the [AGC]

function to AOffB. Otherwise, when the level is

turned too far toward L, the [AGC] function

activates, hence increasing sensitivity and

the picture may look grainy.
