FOCUSING PROCEDURE FOR AUTO-IRIS LENSES
1. Set the dip-switch ELC/ALC selector to ELC position (using Dc driver lenses).
2. Point the camera at the field to be shot and make sure light is sufficient for shooting; rotate the
trimmer LEVEL until the image is totally white. This procedure causes the maximum f-stop aperture,
with the minimum focus field, in order to optimize the focusing of the desired point.
3. Set the dip-switch to ELC position to make the image visible again and with a right contrast.
4. Perform focus adjustment if a fixed lens is used. If the lens is varifocal, adjust zoom and focus.
5. If images focus is not perfect, adjust Easy Back Focus; after adjustment, screw the adjustment pin in
order not to lose the adjustment just performed.
6. Set again the dip-switch to ALC position to obtain again white or white saturated images; adjust the
trimmer LEVEL until image brightness is correct.
