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 is aligned with either the top or bottom edge of the screen area, and 
centered horizontally. See 
Figure 3-2.
Figure 3-2. Projector Placement
Vertical and Horizontal 
Lens Shift
You can use the lens shift (LENS) controls on the projector remote 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 3-3 and Figure 3-4.

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. 
4. With these lenses, horizontal lens shift is not possible when the maximum amount of vertical lens 
shift is used.

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 3-5. The position of the projector and 
mirror must be accurately set. If you are considering this type of installation, contact your 
dealer for assistance.

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 Primary 
Projection Lens 
(VX-3000 Ultra only)
The VX-3000 Ultra primary projection lens is shipped separately from the projector. 
Proceed as follows to install it:
1. Carefully remove the projector from the 
shipping container and place it on a flat 
surface. 
 
 
 
 
 
 
 
 
2. Loosen the Phillips screw at the bottom of 
the decorative bezel on the front of the 
projector.
 
 
 
 
 
 
 
 
3. Grasp the bezel by the front, then rotate and lift it upward to remove it. (Don’t pull it 
straight out.) 
 
 
4. Carefully remove the lens from the shipping container.

5. Remove the rear cap from the lens. 
This protective cap is only used during 
shipping to protect the lens from 
damage. 
 
 
 
 
 
 
 
 
 
 
 
6.Carefully cut and remove the plastic band 
around the lens motor connector wires. 
Take great care not to cut the wires! 
 
 
 
 
 
 
 
 
 
7. Detach the lens motor connector from the 
motor by removing the two screws holding it 
in place. 
 
 
 
 
 
 
 
 
 
8. Note that the lens mount flange has a female 
socket connector for the lens motor on the 
right side of the flange.

12. Gently push the lens assembly in until it is seated flush against the flange and the 
guide pin on the lens assembly is fully seated in the hole on the flange.
 
  
13. Secure the lens assembly to the projector 
flange with the three Allen screws on the 
outer ring of the assembly, using a 3-mm 
hex driver. 
 
 
 
 
 
 
 
 
14. Install the foam shield around the front of the lens. 
  
15. Replace the front lens bezel.
16. Tighten the Phillips screw on the bottom of the bezel to secure it. 
Tighten only these three screws. Do not attempt to adjust any of the 
screws behind the lens flange. Doing so may cause the lens to 
malfunction.

Installing the Optional 
CineWide/AutoScope 
Lens Mount
If you are installing a standard (non-CineWide) VX-3000i, VX-3000d or VX-3000 Ultra, skip 
this step and proceed with 
Mounting the VX-3000 (page 36). 
If you are installing a CineWide projector equipped with a prismatic 
(Whitney) anamorphic lens, proceed with 
Installing the Fixed CineWide 
Base Plate (Prismatic Lens) (page 31). 
 
If you are installing a CineWide projector equipped with a 
cylindrical (Rainier
 II or McKinley) anamorphic lens, proceed 
with 
Installing the Fixed CineWide Base Plate (Cylindrical 
Lens) (page 33).  
If you are installing a VX-3000i/CineWide with AutoScope, VX-3000d/CineWide with 
AutoScope or VX-3000
 Ultra/CineWide with AutoScope, proceed as follows to install the 
AutoScope lens motor.
 
1. Do not install the CineWide lens yet, only the fixed CineWide 
base plate or AutoScope lens motor. You will install the CineWide 
lens after you install the projector and adjust the primary lens.
2. Some components shipped with your projector may differ slightly 
from what is shown in these instructions.
