In order to install auto iris lens one should:

Carefully remove the plug protected the CCD pick-up element

Carefully screw the lens till slight resistance can be felt

Plug the connector into the auto iris jack of the camera
Note:
If lens cable does not end with a connector use the connector supplied with the camera.
According to the lens manual and advices below, one should solder the
cables to the connector and protect them against short circuit by the heat shrink
sleeves.

In the camera menu set lens control as DC

Supply power to the camera, adjust focal length and focus
Note: For best results, perform focus adjustments at night (with iris fully opened) or while
using a #6 or #8 welder's glass in front of the lens to avoid overexposure.
Note: The cameras are equipped with the circuit for iris control with the voltage level ad-
justment in the menu. Default settings are selected for the optimum quality of video
signal. It is not recommended to make any changes if it is not necessary. In case of
changes it is recommended to use #6 or #8 welder's glass in front of the lens and see
the signal on the oscilloscope. During adjustment AGC feature should be switched
