 Use Handles for Hoisting or as Safety Points 
This procedure applies to one or more projectors. To hoist a stack, first stack 2 or 3 
projectors according to the stacking procedure included in this manual. Never stack 
or hoist more than 3 projectors together. 
Remove lens (recommended) 
To prevent possible lens damage during hoisting, remove the lens. See 4.4, Replacing 
the Lamp and Filter. 
Retract feet 
Retract the adjustable feet if the projector is inverted to prevent the hoisting hardware 
from becoming snagged. 
Attach safety cables 
Attach a safety cable to each of the (2) eyebolts 
mounted on the bottom of the projector (Figure 
2.8). 
 WARNING  
Always use at least 2 safety cables for any 
hoisting. 
 WARNING  
Attach safety cables 
to the 2 eyebolts. 
NOTE: When hoisting a non-inverted projector 
or stack, add 2 safety eyebolts in the front and 
rear threaded holes provided on the top of the 
projector. Make sure the eyebolts are rated 
adequately for the load. Secure safety cabling 
to both eyebolts.

 Stacking Procedure  
						

							INSTALLATION & SETUP 
  Roadster / Mirage S+ User’s Manual 2-7 
Position the projectors 
Place the projectors to be 
stacked on a secure table or 
cart. 
• Place one projector on its 
side to access its 
adjustable feet and 
stacking legs (Figure 
2.10). 
• Orient the other projector 
in either upright or 
inverted position as 
required (remember, 
each projector in a stack 
must be in the same 
orientation). 
 
Fully retract the (4) adjustable feet  
Retract each foot as far as possible by turning it clockwise. 
• If upright – retract the feet on top projector. 
• If inverted – retract the feet on bottom projector. 
Extend the (3) stacking legs 
Extend the stacking legs by turning 
them so that at least 1 inch of thread is 
visible on each. This clearance 
accommodates the up-or-down 
movement for aligning the images from 
stacked projectors. Extend all 3 legs 
equally (Figure 2.11). 
• If upright – extend legs on top 
projector (shown).  
• If inverted – extend legs on bottom 
projector. 
 IMPORTANT  
Extend the stacking legs 
equally by at least 1 inch. 
 
 
 
 
 
Loosen the rear stacking leg nuts 
On the rear stacking legs, loosen the nuts so the legs have some lateral movement for 
easier alignment with the stacking mounts on the other projector.   STEP 1

• If upright – release on top projector. 
• If inverted – release on bottom projector. 
Release and remove (3) safety pins 
The safety pins must be removed from the 
stacking mounts so that the stacking legs can fit 
into the mounts (Figure 2.13).  
• If upright – remove the pins from the mounts 
on the bottom projector. 
• If inverted – remove the pins from the 
mounts on the top projector. 
 
 
 
 
 
Place top projector on bottom projector 
 WARNING  
Minimum of 2 people required. 
With one person on each side, lift the top projector on to bottom projector, aligning 
all three stacking points between projectors. Legs should fit inside stacking mounts. 
Align holes in (3) stacking mounts and (3) stacking legs. 
On each stacking mount, turn the adjusting wheel slightly until the hole in the top 
portion of the mount lines up with the hole in the stacking leg (Figure 2.14). 
NOTE: You can increase leverage by using a screwdriver in the holes.   STEP 5

 WARNING  
Critical Safety Procedure. 
At each of the (3) stacking points, insert the safety pin fully through the holes in the 
stacking mounts and stacking legs (Figure 2.14). Ensure that each pin is fully inserted to 
engage the safety lock and secure the projectors together. Failure to engage the safety 
lock could cause the projectors to separate and result in injury or death. 
 WARNING  
Failure to engage the safety lock could cause the 
projectors to separate and result in injury or death. 
Leg Nuts 
Before hoisting, firmly tighten the nuts on the (2) rear stacking legs (Figure 2.14). Or, 
if you are ready to align the projectors to one another, leave these nuts slightly loose 
until after the alignment. 
Repeat STEPS 1–9 for a third projector. 
 WARNING  
Never stack more than 3 projectors. 
Stacked projectors must be correctly aligned to one another so that the resulting 
display is optimized and as sharp as possible. If you are also hoisting the stack, hoist 
the stack into place first, then align. Lock all stacking hardware into place to maintain 
your alignment. 
 IMPORTANT  
Make sure the stacking legs have been extended 
by at least 1 inch, and are slightly loosened.

Front Screen Installations 
While there are two basic screen types, flat and curved, generally flat screens are 
recommended for this projector (Figure 2.17)X. Flat screens offer a gain of about 1 
with a viewing angle just less than 180°. Incident light reflects equally in all 
directions so the audience can see the display from various angles. Because of the 
low gain, flat screens are most effective when ambient lighting is reduced, although 
this difference may be negligible given the high brightness output from this projector. 
  
Figure 2.17. Audience Coverage with Flat Screen Figure 2.17 
NOTE: Lenses for this projector are designed primarily for use with flat screens, but 
the projector depth-of-field range allows the lens to be focused on curved screens as 
well. While focus remains sharp in the corners, there may be significant pincushion 
distortion, primarily at the top of the screen. 
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 increase at the front reduces the intensity in other areas. A viewing cone, 
similar to that of a curved front screen installation, is created.   Screen T

							INSTALLATION & SETUP 
  Roadster / Mirage S+ User’s Manual 2-13 
To summarize, optical screens are better suited for brightly lit rooms where the 
audience is situated within the viewing cone. Diffused screens may be better suited 
when a wide viewing angle is required but there is low ambient room lighting. 
Screen size may vary from 4 feet (122 cm) to 45 feet (1372cm) diagonal, depending 
on the lens you are using. For instance, a 0.73:1 lens can produce a 5 foot (150 cm) to 
a 14 foot (548 cm) image size depending on the location of the projector, whereas a 
4.5-7.3:1 zoom lens produces an 8 foot(160 cm) to 40 foot (438 cm) image size. 
Choose a screen size appropriate for your lens and application. Keep in mind that if 
the projector will be used to display text information, the image size must allow the 
audience to recognize all text clearly. 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 be illegible at a distance no matter how sharply and clearly it is 
displayed. 
Ideally, to fill a screen with an image, the aspect ratio of the screen should be equal to 
the aspect ratio of the image. The aspect ratio of an image is expressed as the ratio of 
its width to its height such as a 4:3 aspect. Standard video from a VCR has a 4:3 
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). 
Aspect ratio (Figure 2.18) describes the proportion of the screen and is expressed as 
the ratio of width to height, such as “4:3” or “5:4”. Although image size and image 
aspect ratio can both be adjusted quickly through projector software, it is still a good 
idea to choose a screen aspect ratio which is most appropriate for your intended 
applications. 
Ideally, to exactly fill a screen with an image, the aspect 
ratio of the screen should correspond to the aspect ratio of 
the image, which depends on the source in use. For 
example, standard video from a VCR has a 4:3 ratio 
(approximately), whereas a high resolution graphics signal 
typically has a 5:4 aspect ratio. By default, images from 
your projector will be as large as possible and will maintain 
their aspect ratio. 
The SXGA+ (1400 x 1050) aspect ratio for the Roadster 
and Mirage models is 4:3. 
The high brightness of this projector is well suited for locations where ambient 
lighting might be considered less than ideal for projection. Even a typical room or 
large auditorium fully lit with ceiling lights and windows rarely requires special 
attention. Contrast ratio in your images will be noticeably reduced only 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. 
In general, avoid or eliminate light sources directed at the screen. 
Other considerations and tips which 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.   Screen Size

• Keep the projector away from devices which radiate electromagnetic energy such 
as motors and transformers. Common sources of these include slide projectors, 
speakers, power amplifiers, elevators, etc. 
• Choose the best screen size for the application. Since more magnification reduces 
brightness, use a screen size appropriate for the venue but not larger than 
required. Installing a large screen in a small room is similar to watching 
television at a close range; too large a screen can overpower a room and interfere 
with the overall effect. A good rule of thumb is to be no closer than 1.5 times the 
width of the screen. 
 
Installation type, screen type, and lighting all affect where the projector is positioned. 
In addition, both throw distance (the distance between the projector and screen) and 
vertical position (the height of the projector in relation to the screen) must be 
determined for every new installation. Both depend on the screen size and lens type 
you are using. Make sure that the room can accommodate the required position of the 
projector for the chosen screen size. 
 
Figure 2.19. Estimating Throw Distance 
(SEE APPENDIX D)  
For any installation, an accurate throw distance (TD) must be determined in order for 
the image to be of the right size for your screen–the farther the projector is from the 
screen, the larger the image. Throw distance is the distance between the projector’s 
front feet axes and the screen (Figure 2.19), and is roughly equal to the horizontal 
width of the screen multiplied by the throw ratio of the installed lens. Once you know 
your screen size and lens, you can estimate throw distance needed. For example: 
• Screen Width = 10 feet 
• Lens Type is 0.7:1 
• Throw Distance (TD) = 10 feet x 0.7 = 7 feet 
NOTES: 1) If your projector is slightly tilted in relation to the screen, typical for 
large venues or flown installations, throw distance still represents the smallest 
measurement between the screen and front feet. 2) For proper placement in an 
installation, always refer to the throw distance formula and/or chart for your lens as 
listed in Appendix D. Keep in mind that due to lens manufacturing tolerances for
