Installation 20 Vidikron Vision 150 Owner’s Operating Manual PREL IMINARY 3.3 Installation Considerations Proper installation of your projector will ensure the quality of your display. Whether you are installing a projector temporarily or permanently, you should take the following into account to ensure your projector performs optimally. Installation TypeChoose the installation type that best suits your needs: front or rear screen, floor mount or inverted mount. Table 3-2 compares these various installation methods. Ambient LightIn general, minimize or eliminate light sources directed at the screen. Contrast ratio in your images will be noticeably reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant. ➤ Table 3-2.

Installation Vidikron Vision 150 Owner’s Operating Manual 21 PREL IMINARY Throw DistanceThrow distance is the distance measured from the front of the projector to the screen. This is an important calculation in any projector installation as it determines whether or not you have enough room to install your projector with a desired screen size and if your image will be the right size for your screen. You can quickly estimate the throw distance by taking the width of the screen and multiplying it by the lens throw ratio; see Figure 3-2. The result of this calculation tells you roughly how far back the projector should be positioned from the screen in order to project a focused image large enough to fill the screen. Figure 3-2. Estimating Throw Distance Table 3-3 lists the available lens options for the Vision 150 and their associated throw ratios. Table 3-3.

Throw distance does not affect image quality, provided these ranges are taken into account. 2. Only lens options D and E can be used with the optional CineWide (secondary anamorphic) lens. Doing so affects the throw distances as shown here. Estimating Throw Distance Throw Distance (TD) = Screen Width (w) x Lens Throw Ratio Screen width (w) TD
Installation 22 Vidikron Vision 150 Owner’s Operating Manual PREL IMINARY Vertical and Horizontal Position Proper placement of the projector relative to the screen will yield a rectangular, perfectly-centered image that completely fills the screen. Ideally, the projector should be positioned perpendicular to the screen and in such a way that the lens center and screen center are aligned with each other, as shown in Figure 3-3. Figure 3-3. Projector Placement Vertical and Horizontal Lens Shift If it is not possible to align the projector and screen as shown in Figure 3-3, you can use the lens shift controls to center the image on the screen. Lens shift is generally expressed as a percentage of the screen height or width, as shown in Figure 3-4 and Figure 3-5. Figure 3-4.

With no vertical or horizontal lens shift, the lens center and screen center are aligned with each other. 2. Vertical shift limits are percentages of the screen height. Horizontal shift limits are percentages of the screen width. 3. Vertical lens shift figures are for ceiling mount configurations. For floor installations (where the projector is upright), reverse the up/down vertical lens shift percentages.
Installation Vidikron Vision 150 Owner’s Operating Manual 25 PREL IMINARY Folded OpticsIn rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical path, as shown in Figure 3-6. The position of the projector and mirror must be accurately set. If you are considering this type of installation, contact your dealer for assistance. Figure 3-6. Folded Optics Other ConsiderationsOther considerations and tips that can help improve your installation: Keep the ambient temperature constant and below 35°C (95°F). Keep the projector away from heating and/or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry, which may affect performance. Keep the projector away from devices that radiate electromagnetic energy such as motors and transformers. Common sources of these include slide projectors, speakers, power amplifiers and elevators.

Installation 26 Vidikron Vision 150 Owner’s Operating Manual PREL IMINARY 3.4 Installing the Projection Lens The projection lens is shipped separately from the projector. Proceed as follows to install the projection lens: 1. Remove the lens plug from the lens opening in the projector. 2. Place the lens cap on the projection lens to protect it from being damaged during the installation process. 3. Remove the rear cap from the lens. This protective cap is only used during shipping to protect the lens from damage. 4. Slide the new lens into the lens opening of the projector. Make sure to align the connector on the side of the lens with the connector assembly on the lens retaining ring; see Figure 3-7. As you connect the lens, you may have to re-align it slightly until the tabs on the lens fit into the slots in the lens retaining ring. Figure 3-7. Lens Assembly (Front View) 5. With the lens fully inserted (and connected), turn it clockwise until the lens release button “pops” indicating the lens is fully inserted.
Installation Vidikron Vision 150 Owner’s Operating Manual 27 PREL IMINARY 3.5 Installing the Optional CineWide Lens Mount If you are installing a Vision 150 with the optional CineWide or CineWide with AutoScope system, proceed as follows to install the anamorphic lens mounting assembly (stationary base plate or AutoScope lens motor). Remove Projector Front Feet (CineWide with AutoScope) (Skip this step if you are installing a fixed CineWide anamorphic lens.) Place the projector upside down on a blanket or other soft surface. Loosen and remove the two front feet on the projector. Install Anamorphic Lens Motor (CineWide with AutoScope) or Base Plate (fixed CineWide) CineWide with AutoScope: Line up the eight mounting holes on the lens motor housing with those on the bottom of the projector. Secure the motor to the projector with the eight screws provided for this purpose. Fixed CineWide: Line up the seven mounting holes on the lens mount base plate with those on the bottom of the projector, directly below the primary lens. Secure the base plate to the projector with the screws provided for this purpose. 1. Do not install the CineWide lens yet, only the mounting plate or lens motor. You will install the CineWide lens after you install the projector and adjust the primary lens. 2. Some of the following steps are necessary only for CineWide with AutoScope installations. Note The anamorphic lens mounting kit is partially pre-assembled at the factory – the AutoScope lens motor and lens mounting assemblies are both fully assembled. Note
Installation 28 Vidikron Vision 150 Owner’s Operating Manual PREL IMINARY Install Projector Stand (CineWide with AutoScope, Floor-Mount) (Skip this step if you are installing a fixed CineWide anamorphic lens, or ceiling-mounting an AutoScope-equipped projector.) If you are installing the Vision 150 in an upright position (not ceiling-mounted), use the supplied hardware to attach the projector stand to the bottom of the projector as shown below. This stand allows the projector to lie flat on the mounting surface with the AutoScope lens motor installed. DO NOT OVER-TIGHTEN THE SCREWS. Caution ➤ AutoScope stand used for floor-mounted projector
