To change the settings for auto iris:

1. Program preset 95 (28). The main menu appears.

2. Position the cursor (>) beside Camera.

3. Press the Iris Open button to enter the Camera menu.

4. Position the cursor (>) beside Auto Iris.

5. Press the Iris Open button. The Auto Iris menu appears.

6. Position the cursor (>) and select one of the following settings:

MODE – The cursor moves to one of two choices:

Auto – The iris is automatically adjusted to produce a constant video output as determined by the Level setting.

Off – Auto iris is disabled, and control is always manual.

Move the joystick up or down to toggle between Auto and Off. 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 system 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.

PEAK – The cursor moves to a numeric value. Increasing this value will cause the auto iris circuit to react more to highlights or

“peaks” in the picture. Decreasing this value will cause it to use the average video level to adjust the iris. 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.
