MANUAL IRIS LENS ADJUSTMENT

When using a manual iris lens, turn the iris ring on the lens to the OPEN
position and adjust the manual iris for the appropriate range. Adjust during the
brightest conditions, opening the lens to the minimum f-stop yielding a good
picture under the brightest scene conditions. Do not saturate the picture.
The manual iris is used in indoor applications where lighting from windows can
considerably affect the light level of the room.
