Operation

VAC: Use the VAC control to increase or decrease the V² Aperture Control setting. VAC lets you control the aperture or iris size (the physical opening through the lens; similar to an “f-stop” on a camera). Doing so allows you to optimize brightness and contrast according to the amount of ambient light in the viewing area.

Use a higher setting for rooms with a lot of ambient light. Use a lower setting for more “theater-like” viewing conditions (little or no ambient light).

12-volt Trigger: Select 12-volt Trigger from the Setup menu to configure the 12-volt trigger output.

•Set the 12-volt Trigger to Normal if you want the trigger to activate when the projector is turned on (for instance, if the trigger is controlling a retractable screen).

•Set the 12-volt Trigger to Cinema if you want the trigger to activate when the Cinema or IntelliWide 2.35 aspect ratio is selected. Choose this setting if your Vision 65/75 is equipped with the Vidikron CineWide with AutoScope system.

V. Correction: To achieve the proper image geometry with the secondary anamorphic lens, select V. Correction from the Set Up menu. Then, use the or button to change the native aspect ratio of the display, in small increments.

Amplitude: The Amplitude menu allows you to fine-tune the aspect ratio by compressing it horizontally or vertically, in small increments. This can be useful if your projector is equipped with an anamorphic lens.

The Horizontal control adjusts the image width while keeping the height constant. Similarly, the Vertical control adjusts the image height while keeping the width constant.

Auto Off: When using the Vision 65/75 with a computer, use the Auto Off feature to have the Vision 65/75 go into standby mode when no source signal is present on the current input. (A warning message appears on-screen for approximately eight seconds before this occurs.) Select an Auto-Off interval of from five to 30 minutes, in five-minute increments. To return to normal operating mode from the Auto Off standby mode, select the input with the remote control or operate your computer.

When Auto Off is disabled, the Vision 65/75 remains in normal operating mode, regardless of the presence or absence of an input sync signal.

1. If the computer is turned off or not properly connected to the Vision

Note	65/75, the system is set to the off state.
