2. Attach the video-type auto iris lens to the lens mount on the front of the
camera.
3. Plug the connector from the lens into the auto iris jack on the back of the
camera. The connector is polarized and can only be inserted into the jack
one way.
4. The E/I switch should be in the “OFF” position.
5. The A/I switch should be in the “VID” position.
6. Apply power to the camera.
7. Adjust the focus ring on the lens for an optimum picture. If a picture is not
visible, set the lens for proper exposure by adjusting the ALC (Automatic
Level Control) and the level on the lens. The ALC setting can range
between AVG (average) or PK (peak). A midrange setting is appropriate
for most applications.
