Appendix A: Projector 
Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a theater or conference room.
Placement and Mounting Guidelines
The projector can be installed for four different viewing setups: front 
projection, ceiling mounting, rear projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll need the optional ceiling mounting 
hardware; see...

112Appendix A: Projector Installation
Lens Shift is better than angling the projector up or down to position 
the image, since it won’t produce keystone distortion, which must be 
eliminated electronically. 
If you mount the projector on the ceiling above screen level, you’ll 
have to tilt it down to center the image on the screen. This causes the 
image to lose its square shape, but you can correct the distortion by 
using the 
Keystone function in the projector’s menu system (see 
page 67) or by...

Image Size Calculations (For All Lenses)
Use the formulas in this section to estimate the required screen size 
and placement of the projector, depending on the type of lens with 
which your projector is equipped. For all lenses except Rear Projection 
Wide, the image size can be adjusted with the Zoom function, as 
indicated by the minimum and maximum calculations.
Standard Lens (V12H004S02)
Image size: 22 to 600 inches (0.56 to 15.24 m)
Projection distance (focal...

114Appendix A: Projector Installation
Middle Throw Zoom Lens (V12H004M01)
Image size: 60 to 600 inches (1.52 to 15.24 m)
Projection distance (focal range): 114 to 1791 in. (2.90 to 45.49 m)
■To find the image size when you know the projection distance:
Maximum diagonal size = (0.5055 × projection distance) + 2.7
Minimum diagonal size = (0.3340 × projection distance) + 1.8
■To find the projection distance when you know the image size:
Maximum projection distance = (2.9941 × diagonal size) – 5.3
Minimum...

Appendix A: Projector Installation115
Converting Between Diagonal Size and Width 
or Height
The calculations on the previous pages use the diagonal length of an 
image to indicate its size. 
■Use these formulas if you want to find out the diagonal size of a 
4:3 image from its width or height:
Diagonal size = 5/4 × width
Diagonal size = 5/3 × height
■Use these formulas if you want to find out the width or height of 
a 4:3 image from its diagonal size:
Width = 4/5 × diagonal size
Height = 3/5 × diagonal...

Installing the Rear Cable Cover
If you’re mounting the projector 
on the ceiling, install the rear 
cable cover to enhance the 
appearance of the system. To 
install the cover, insert its tabs 
into the slots as shown, then 
push the cover against the 
projector until it locks into place.
To remove the cover (when 
replacing the lamp and 
connecting or disconnecting 
cables), release the locking tab on 
the bottom of the cover as shown:
