Camera Adjustments

To perform the following camera adjustments, make sure to connect the camera and service connectors. You may have to remove the camera module from the back box.

Connect a monitor. Then turn on power to the camera and monitor. To use the service connector, refer to Service Connector on page 27.

To set the DIP switches, or to adjust the auto iris level (DN or CH) or the vertical phase (DW or CW), you will need a miniature trimpot adjustment tool with a 0.05-inch (1.27 mm) blade. Suggested tools include a miniature flat-tip screwdriver, a Philmore trimpot tool (#63-8608), and the Philmore 10-piece tool set (#63-910). To adjust the lens, you may also need a miniature Phillips screwdriver.

After you have adjusted the unit, reinstall the camera module into the back box, and then install the trim ring, bubble, and liner (if necessary).
