Press the Iris Open button to select the choice, or press the Iris Close button if you do not want to change the setting.

LEVEL - The cursor moves to a numeric value, which the Spectra II™ dome uses to try to maintain a certain light level. Changing the value of the Level setting will change the video level to which the auto iris adjusts. This setting should be adjusted if the video level in the auto iris mode is too bright or too dark. Move the joystick up or down to a value. Press the Iris Open button to select the value, or press the Iris Close button if you do not want to change the setting.
