Bottom
The standard hole for installation on the bottom surface is useful for
reference when measuring for installation. There are seven holes on the
bottom surface of the projector. For ceiling installation using the optional
PSS-90 Projector Suspension Support, use five holes to attach the PSS-90.
The other two holes are spare ones.
Notes
•Use only the M8 meter screws of 10 mm (13/32 inches) to 30 mm (13/16
inches) long for the attachment holes for the PSS-90.
•When attaching the PSS-90, use the M8 meter screws of 20 mm (25/32
inches) supplied with the PSS-90.

Notes on Screen
Screens with an aspect ratio other than
4:3
When the height is greater
Calculate the screen size with 4:3 aspect ratio from the
screen height as shown below. Install the projector and
screen in accordance with the screen size obtained.
--- : Screen whose aspect ratio is 4:3
Screen size (inch) = (height (mm) ×5/3) ×1/25.4
Example: When the screen height is 1500 mm
(1500 (mm) ×5/3) ×1/25.4 = Approx. 98 inches
When the width is greater
Calculate the screen size with 4:3 aspect ratio from the
screen width as shown below. Install the projector and
screen in accordance with the screen size obtained.
---: Screen whose aspect ratio is 4:3
Screen size (inch) = (width (mm) ×5/4) ×1/25.4
Example: When the screen width is 2000 mm
(2000 (mm) ×5/4) ×1/25.4 = Approx. 98 inches
Screen size
The screen size is the diagonal length of the screen in
inches, while the aspect ratio of the screen is 4:3. The
ratio of the screen height, width, and diagonal is 3:4:5.
4
35
If you use a screen with 4:3 aspect ratio whose size is
not given in the table below, you can calculate the
screen height and width from the screen size (inches)
as follows.
Calculate at the conversion rate of 25.4 mm to the
inch.
Height (mm) = Screen size ×25.4 ×3/5
Width (mm) = Screen size ×25.4 ×4/5

Types of screen
Rear projection screen
A screen manufactured using two sheets, the fresnel
and lenticular, is recommended for a bright and clear
full-screen picture projection.
White screen
When viewers watch the projected picture in a wide
area, you can obtain a picture that appears equally
bright from all parts of the room using the white screen
for both floor and ceiling installations. Note that you
will not be able to get a clear picture in this case unless
the room is dark.
Front projection screen for floor installation
The bead screen is recommended. A screen of this type
reflects the brightest light.
Front projection screen for ceiling installation
The silver screen is recommended. You can get a
picture that is two to four times brighter than that of
the white screens.

When the Screen Size is not Mentioned in the Tables
You can calculate the installation measurements described below when
you use the screen whose size is not mentioned in the tables on pages
12(GB) and 14 (GB).
Check your installation conditions:
•Screen size to be used (S)
•Installation measurements at the end of the manual, ES and BS for
smaller screen size and EL and BL for larger screen size
See the tables on pages 153(GB) to 158(GB).
Now you can calculate the installation measurements as follows:
E (mm) = ES + ((S – smaller screen size) ×(EL – ES) ×0.1)
B (mm) = BS + ((S – smaller screen size) ×(BL – BS) ×0.1) + 289
Example: when using 124-inch screen
According to the tables on page 154 (GB), the values E and B are as
follows:
ES = 3279, BS = 791 (As the smaller screen size is 120 inch.)
EL = 3570, BL = 861 (As the smaller screen size is 130 inch.)
Therefore,
E (mm) = 3279 + ((124 –120) ×(3570 – 3279) ×0.1) = 3395.4 (mm)
B (mm) = 791 + ((124 – 120) ×(861 – 791) ×0.1) + 289 = 1108 (mm)

Floor Installation Using Rear Projection Flat Screen
What is the optical axis angle?
The optical axis angle is the angle between the horizontal level line and the
straight line from the center of the projector’s green lens to the center of
the screen. When using a rear projection screen, you can get the brightest
picture when the center of the screen is aligned with a straight line
extension of the center of the green lens.
Therefore, the most suitable optical axis angle varies depending on the
height of the screen and your line of sight.
When the optical axis angle is 2°
