features available on the Accurate series. This circuitry interfaces with the keypad to
provide projector control by the user, such as:
* Turning the projector on or off
* Switching input sources
* Adjusting all display settings such as contrast, brightness, and size
* Correcting for display effects and input noise
*Displaying projector operating status screens and on-line help
*Controlling projector operating settings
Should projector servicing be required, service personnel can use the keypad to make
service adjustments and alignments. In some cases the projector may be

INSTALLATION & SETUP
2.2 Installation Considerations
Careful consideration should be given as to how and where the projection system is
installed. Although the projector offers high performance, the final display quality could
be compromised if the projector is not installed properly. This subsection discusses the
considerations you should make before proceeding with a final installation. These
considerations include the installation type (floor, ceiling, rear), screen size and type,
room lighting, and ventilation.

INSTALLATION & SETUP
Screen Type >
Screen type is a very important factor when designing a projection system.
Inexperienced users or installers should always consult their dealer when deciding on
screen type. The following guidelines may be helpful to understand the differences
between screen types.
Front Screen Installations
There are two basic screen types: flat and curved. The choice between a flat screen versus
a curved screen is dependant on audience viewing angle and screen gain. There is always
a trade-off between viewing angle and gain. Viewing angles for both screen types are
illustrated in Figures 2-1 and 2-2.
Flat screens offer a gain of about 1 with a viewing angle just less than 1800. Incident
light reflects equally in all directions so the audience can see the display from various
angles. Because of the lower gain, flat screens are more effective when ambient lighting
is reduced.
Curved screens have gains larger than 1 and viewing ogles much less than 1800. Most
curved screens have different horizontal and vertical viewing angles. Incident light does
not reflect equally in all directions. The reflected light concentrates in a conical volume
or ''viewing cone''. Audiences within the viewing cone see a brighter image than that
from an equal area on a flat screen. Audiences outside the viewing cone see a dimmer
image.
2-3

INSTALLATION & SETUP
To summarize, curved screens are better suited for brightly lit rooms where the audience
is situated within the viewing cone. Flat screens are best suited when a wide viewing
angle is required and ambient room lighting (near the screen) is low.
Note: Screen Gain is defined in Appendix A, Glossary.
Rear Screen Installations
There are two basic types of rear screens: diffused and optical. A diffused screen has a
surface, which spreads the light striking it. Purely diffused screens have a gain of less
than 1. The main advantage of the diffused screen is its wide viewing angle, similar to
that of a flat screen for front screen projection.
Optical screens take light from the projector and redirect it to increase the light intensity
at the front of the screen. This reduces it in other areas. A viewing cone, similar to that of
a curved front screen installation, is created.
To summarize, optical screens are better suited for brightly lit rooms where the audience
is situated within the viewing cone. Diffused screens are best suited when a wide viewing
angle is required but there is low ambient room lighting.
Screen Size and Throw Distance >
Screen size and throw distance are interrelated. See Appendices F and G. As screen size
increases, the distance between the projector and the screen also increases. During
projection room design, make sure that the room can accommodate the required position
of the projector for the screen size you need.
Screen Size
Screen sizes vary according to model and lens type. See Appendices F and G.
Choose a screen size, which is appropriate for your application. If the projector will be
used to display text information it is important that the image size allows the audience to
clearly resolve all text. The eye usually sees a letter clearly if eye-to-text distance is less
than 150 times the height of the letter. Small text, located too far from the eye, may not
be legible at a distance even though it is projected sharply and clearly on the screen.
To fill a screen with an image, the aspect ratio of the screen must be equal to the aspect
ratio of the image. The aspect ratio of an image is the ratio of its width to its height.
Standard video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a
VCR output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the
screen must be at least 13.3 feet (4m).
Note: Screen size is often specked as diagonal size. Screens specked by diagonal size
have aspect ratios of 4:3. Screens with other aspect ratios are not typically specked by
diagonal size.
2-4

INSTALLATION & SETUP
Throw Distance
The throw distance (projector-to-screen distance) must be determined for every new
installation. Throw distance, the distance between the projector's center lens and the
center of the screen, is based on screen size. As screen size increases, the distance
between the projector and the screen increases. Make sure that the room can
accommodate the required position of the projector for the chosen screen size.
Once your screen size is known you can determine the required throw distance for your
projector model and lens by using the formulas in Appendix G and tables in Appendix F.
Notes: 1) Calculated values are for reference only. It is good practice to simulate the
setup to determine the necessary throw distance. 2) Display size isaffected by input
signal characteristics. Once the projector is set, use the Size function to finetune display
size.
Throw distance and projection angle: Keep in mind that the ability to properly focus all
areas of the image is limited if a significantly tilted projector is too close to the screen.
Lighting >
Proper lighting is another important factor when designing a projection room.
Visiting a movie theatre can give you an idea of what makes a good projection
environment. A1l walls, floors and furnishings are dull colored and non-reflectively
finished. Every effort should be made to create the best environment for your system.
When designing a projection room, try to avoid white, reflective ceilings and non-
directional lighting such as fluorescent lights. The white ceiling spreads the light, which
makes the room appear brighter. You want to keep the lighting and reflections to a
minimum. If it is not possible to keep fluorescent lights off, consider using parabolic
reflectors (''egg crates'') to direct light down to the floor and away from the ceiling. Spot
lighting (incandescent) is a better way to obtain illumination. Installing light dimmers or
rheostats allows you to control your lighting environment.
Outside windows are undesirable in any projection environment. A small crack between
curtains on a sunny day can severely wash-out an image. Make sure that curtains are
opaque and fit snugly. Some curtains can provide up to 100 percent blockage of outside
light. Pay close attention to the curtain material facing inside the room. It should have a
matte finish.
Even with no external light at all, reflections from room surfaces can degrade the image.
Light from the screen should be absorbed by surfaces so that it will not be reflected back
to the screen. Keep reflective surfaces to a minimum.
2-5

INSTALLATION & SETUP
To minimize the effects caused by unwanted light from door and aisle ways, carefully
choose the position of your projector and screen. Figure 2-3 shows an installation where
poor screen placement has allowed too much unwanted light to enter the screen. In figure
2-4 the screen and the projector are positioned so that unwanted light is minimized.
Other Considerations >
Here are some other considerations and tips, which can help you improve the design of
your projection system.
*Proper ventilation is important. The ambient temperature should be kept constant and
below 35 degrees C. (95 degrees F.). Keep the projector away from heating and/or air
conditioning vents. Changes in temperature can cause drifts in the projector circuitry,
which may affect performance.
*Keep the projector away from devices, which radiate electromagnetic energy such as
motors and transformers. Common sources of these are slide projectors, speakers, power
amplifiers, elevators, etc. Keep 35 mm slide projectors at least 2 feet away from the
projector. Even if both are not used at the same time, the magnetic fiends created by the
slide projector can cause permanent magnetization of the projector.
2-6

INSTALLATION & SETUP
* For rear screen applications, less space is required if a mirror is used to fold the optical
path.
*Choose the right screen size for your application:
-As screen size increases, magnification increases which reduces brightness. This
reduces the contrast ratio, which affects legibility. Sharp defined edges become
soft and fuzzy. Consider whether screen size is more important.
-Installing a large screen in a small room is similar to watching television close
up; too large a screen can overpower a room. A good rule of thumb is to be no
closer than 1.5 times the width of the screen.
-Larger screens require greater attention to lighting conditions.
* When laying out your projection room, consider positioning the projector and screen in
a manner, which will achieve maximum audience coverage and space efficiency. For
example, placing the screen along the larger wall in a rectangular room will reduce
audience coverage.
2.3 Hardware Setup
This section explains: how to convert the keypad from a built-in keypad to a remote
keypad, how to change keypad protocol and backlit settings, and how to determine if
reverse scan setup is required.
Keypad Conversion >
The projector includes a multi-use full-function keypad, which may be configured for use
as a built-in IR remote, or wired remote keypad. The keypad is configured at the factory
for built-in use. It is located below the front top cover. You can use the keypad as it is or
re-configure it for remote operation. You can also ''hard wire'' the keypad to be a protocol
A or protocol B keypad (see section 3.7, Utility Features for information about keypad
protocols).
2-7

INSTALLATION & SETUP
Follow the steps below to convert the keypad to a remote keypad and change its protocol
setting.
Step 1
Unplug the projector then remove the front top cover to access the built-in keypad. To
remove the cover, remove the four screws holding it to the projector, two on the right and
two on the left. Grasp it above firmly then pull straight out from the center of the
projector. The keypad is mounted to a securing bracket located above the lens
assemblies. Loosen the two bracket wing nuts then move the keypad away from the
bracket.
Step 2
Locate the battery compartment at the backside of the keypad. Squeeze the latch to open
the door.
See Figure 2-7.
If converting the keypad to an IR remote, unplug the cable connector. Locate the jumper
wires next to the cable connector location. See Figure 2-8. The jumper wires control the
keypad's operating settings.
2-8

INSTALLATION & SETUP
JPI
This jumper setting is important if the keypad is configured for remote operation. There
are two keypad protocols: A and B. These protocols are available to allow two projectors
in the same room to be independently controlled by separate remote keypads. The
protocol setting of the keypad must match that set in the projector's Keypad Options
menu ( UTIL 6 then 1 ). For more information about keypad protocols, refer to the
Remote Control Options entry in section 3.7, Utility Features.
JP2
This jumper must always be set between pins 1 and 2 as shown; otherwise, the projector
will not respond correctly to keypad commands.
JP3
This jumper must always be set between pins 1 and 2 as shown; otherwise, the backlit
feature will be disabled and the projector will not respond correctly to keypad commands.
JP4
The JP4 jumper setting sets the keypad type. If you are converting the keypad to an IR
remote, move the JP4 jumper from between pins 2 and 3 to between pins 1 and 2.
Step 3
For an IR remote keypad, place four AA size,1.5V alkaline batteries in the compartment
ensuring that the +/-orientation of each battery is correct. Position the compartment door
into place.
For a wired remote keypad, an optional accessory cable (#03-001106-02P) is required.
Plug the cable into the cable connector then position the door into place. Plug the cable
jack into the remote jack input on the projector.
WARNING: DO NOT INSTALL BATTERIES IN THE KEYPAD IF A BUILT-IN
OR WIRED REMOTE CABLE IS ATTACHED TO IT. THIS MAY CAUSE THE
BATTERIES TO EXPLODE.
Keypad Operating Settings >
The keypad includes its own memory to store keypad-operating settings. With a few
simple keystrokes you can over-ride the ''hard wire'' protocol setting (explained earlier)
and enable or disable the backlit feature. Keypad battery life is increased if the backlit
feature is disabled. The new operating settings are stored in the keypad until the batteries
are replaced (IR remote keypad) or the keypad connection cable is unplugged (wired or
built-in keypad).
2-9

INSTALLATION & SETUP
If the keypad is configured for IR remote operation, make sure the batteries are installed.
If it is configured for built-in or wired remote operation, make sure its extension cable is
properly connected to the projector. Perform the following keystroke sequences to change
its operating settings:
To toggle the keypad's protocol setting (A or B), press
* BRITE TINT DETAIL then 1.
To toggle the backlit feature (enable or disable), press
* BRITE TINT DETAIL then 3.
To return all configuration settings to the jumper settings, press
* BRITE TINT DETAIL then 0.
Note: The projector will not respond to keypad commands (you press * BRITE TINT
DETAIL then 2.If pressed accidentally, press * BRITE TINT DETAIL
then 0 to clear all keystroke settings.
Reverse Scan >
If the projector is not installed in a front screen, floor mount configuration, reverse scan
setup may be required. Reverse scan setup must be performed by a qualified Accurate
Imaging service technician. Refer to Table 2-2 to determine if reverse scan setup is
required. Contact your dealer for assistance.
2-10

INSTALLATION & SETUP
2.4 Mounting
The projector should be mounted after the system design has been established and reverse
scan setup (if required) is complete.
Front Screen Installations >
Floor Mount
Mount the projector on a secured table or cart. Position the projector at the chosen room
location with the projector pointing towards the center of the projection screen. The angle
of projection, combined with the tilt angle of the screen should direct the reflected image
towards the center of the audience. It is recommended that the difference between the
projection angle and the screen tilt angle (within a common reference) be less than 15
degree. Refer to Figure 2-9.
You can adjust projection angle and level by adjusting the height of the projector legs.
See Figure 2-10.
2-11

INSTALLATION & SETUP
Ceiling Mount
Mounting the projector to the ceiling requires the use of a projector ceiling mount fixture.
The fixture is shipped from the factory in kit form (with assembly instructions) for
assembly and installation by the dealer/installer. For more information, contact your
dealer or Accurate Imaging.
Position the projector so that it is pointing toward the center of the projection screen. The
angle of projection combined with the tilt angle of the screen should direct the reflected
image towards the center of the audience. It is recommended that the difference between
the projection angle and the screen tilt angle (within a common reference) be less than 15
degrees. See to Figure 2-11.
Instructions for adjusting projection angle are provided with the fixture kit. For more
information, contact your dealer or Accurate Imaging.
Rear Screen Installations >
When installing a rear screen system, the vertical positioning of the projector is
dependant on the type of rear screen being used. There are two basic types of rear
screens: optical and diffused.
Optical Rear Screen Systems
If the system includes an optical rear screen, mount the projector along the center axis of
the screen as shown in Figure 2-12.
2-12

INSTALLATION & SETUP
Diffused Rear Screen Systems
If the system includes a diffused rear screen, floor mount or ceiling mount the projector
so that the image is directed to the center of the audience. Projection tilt should be less
than 15 degrees. See Figure 2-13.
In situations where the space behind the projector is limited, a mirror may be used to fold
the optical path as illustrated in Figure 2-14. If a diffused screen is used, the projection
angle 0 should be less than 15 degrees. If an optical screen is used, the optical path
between the mirror and the screen should be perpendicular to the screen. Much attention
must be given to the positioning of the projector and the mirror. This can be quite
difficult for installers unfamiliar with this type of installation. It is recommended that
your dealer or an experienced installer perform the installation.
Note: When using a mirror as shown in Figure 2-14, the calculated throw distance (D) is
the summation of D1 and D2.
2-13

INSTALLATION & SETUP
2.5 Power Connection
To apply power to the projector, plug the AC line cord into the line input socket located
at the front panel of the projector. Plug the three-prong end of the line cord in a grounded
AC outlet. Input voltage to the projector must be between 90 and 264 VAC, 50 or 60 Hz.
The power source must supply 650 watts of power to the projector.
2.6 Source Connections
The projector includes a built-in RGB input interface for connection of external RGB
sources and audio equipment. This input interface is shown in Figure 2-16. The built-in
interface is not removable.
Optional interface modules are available to accommodate other signal types. These
include a Composite/a-video Module, an HDTV Input Module, and a PC Analog Input
Module. Any one of these can be installed in slot 2. A Multi-standard Decoder may be
installed to add four additional inputs to the system (''slots'' 3 to 6). To further increase
the number of inputs, a signal switcher may be connected to the RGB interface in slot 1
to add 8 more sources to the system (9 switcher inputs replace one RGB input). Other
switchers may be connected to the first switcher for more inputs. Brief descriptions of the
above mentioned optional modules are given in Appendix H, Interfaces. For additional
details, contact your dealer and Accurate Imaging.
