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.

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 140/150 and their associated throw 
ratios.

Notes:
1. 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.

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.

Notes: 
1. 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.

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.

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.

Installing the Optional 
CineWide Lens Mount
If you are installing a Vision 140/150 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

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 140/150 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
