Connect the lens cable plug to the auto iris lens socket provided on the left-side face of the camera.
It is recommended that you use a CS-mount DC auto iris megapixel lens (optional).
Keep the lens clean at all times.
The conversion ring (optional) is required to use a C-mount lens.
The lens cable plug must be changed if it does not fit into the auto iris lens socket. If so, contact the
distributor from which you purchased the product (or the agent that provides the installation service).
