c. Use the UP/DOWN ARROWS to select which lamp is currently installed. Make sure the lamp type is also 
indicated on the lamp door label.
Once the Status Display shows the correct lamp type, the projector and lamp can be switched ON.
NOTE: Lamp size can also be changed in the Service menu (Service password required) if the projector is 
running, but it will not take effect until the next power-up. Whenever possible, define the lamp size before 
igniting the lamp
.
6.Switch the projector and lamp ON. Using either the built-in keypad or the standard IR remote, do one of 
the following to switch the projector ON, and ignite the lamp:
• press and hold 
POWER for at least two seconds
• press 
POWER and then press the UP or DOWN Arrow key (useful if you are unsure of the present state of 
the projector)
• press 
POWER twice quickly to toggle from the projector’s present ON/OFF state
The main PROJ. STATUS light at the rear of the projector should be green when the projector is up-and-
running. For best results, let the projector warm up for about 5 minutes.
7.Select the source. Using either the IR remote or built-in keypad, press the appropriate Input key (1-6) to 
display the image for the corresponding source connected as described in Step 3. The display will resize as 
needed, producing an image as large as possible for the type of source present.
8.Adjust the Image. Adjust the more common image settings, such as Brightness, Contract, Gamma, etc. 
using the keys directly on the standard IR remote.
You can also access the Menu system and adjust these and other image settings by pressing 
MENU on the 
standard IR remote.

9.Adjust the lens. Use the Focus button on the standard IR remote or the built-in keypad to focus the image. 
Use the Zoom buttons to increase or decrease image size (not available with fixed 0.8:1 and 1:1 lenses). 
Use the Lens Shift button, and the ARROW keys to shift the image location. Refer to Section 3.14 
Working with the Lenses on how to use the motorized lens mount and Section 2.4.1 Lens Installation for 
instructions.
10.Set Cable Length. In the 
Lamp menu, set the Cable Length (m) slidebar to match the length of the high-
voltage DC cables connected between your lamp ballast and projection head. This regulates the voltage 
drop that occurs over distance, and ensures that adequate voltage reaches the lamp. Particularly in 
projectors rented for temporary installations, this setting may have to be changed from its last use. 
Adjustment range is 2-30m (6½-100 ft.).
Setting the Cable Length also allows you to achieve the same lumens, regardless of cable length. 
However, to drive the lamp at maximum power, even with the shorter ballast cables, set Cable Length to 
maximum power. Due to the resistance losses that occur with longer ballast cables, the ballast does not 
achieve the same maximum power.
Press 
AUTO SETUP and/or MENU to refine other display parameters as necessary. Refer to Section 3.6.3 
Image Settings Menu.
2.2 Installation Considerations
Although the Roadie HD+35K is carefully engineered to deliver exceptional quality, high brightness, and high 
resolution output, your final display results could still be compromised if the projector is improperly installed. 
This subsection discusses issues to consider before proceeding with a final installation. Even for temporary 
installations, this information helps you to better understand what may be done to ensure optimized images.
2.2.1 Screen Type 
Front Screen Installations
This projector is intended for use with flat or slightly curved screens, front or rear, ranging from about 1.5 
meters (5 ft.) to 45 meters (150 ft.) wide. Although flat screens generally offer a low gain similar to a matte 
white wall paint-approximately 1 with a viewing angle just under 180°- and are considered most effective 
when ambient light is low, this difference in gain may be negligible given the very high light output from this 
projector. In addition, incident light reflects equally in all directions so the audience can see the display from 
more acute viewing angles. See Figure 2-6
.

Roadie HD+35K User Manual2-7020-100340-02 Rev. 1  (01-2010)
NOTE: Roadie HD+35K lenses are designed primarily for use with flat screens, but the projectors depth-of-field 
range allows the lens to be focused on mildly 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 rear screen has a surface that 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 rear 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, and creates a viewing cone similar to that of a curved front screen installation.
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.
2.2.2 Screen Size
Screen size (image size) may be up to 150 feet across, depending on your lens and ambient light level. Choose 
a screen size appropriate for your lens and application. Keep in mind that if the projector will be used to 
display much 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. In other words, 
small text that is simply located too far from the eye will be illegible no matter how sharply and clearly it is 
displayed.
NOTE: Screens with aspect ratios (proportion) of 4:3 are typically specified by diagonal size, but screens having 
other aspect ratios, such as the 2048 x 1080 of the Roadie HD+35K, are usually specified by their 
horizontal width. See 
Table 2.1 below:
2.2.3 Screen Aspect Ratio
Aspect ratio describes the proportion of the display and is expressed as the ratio of width to height, such as 
5:4 or 16:9. Typical aspect ratios range from 1.25 to 2.35, the higher the value, the wider or less square 
the image. 
Refer to Ta b l e  2 . 2 below.

Section 2: Installation and  Setup 
Although image size and aspect ratio can be adjusted using projector software, it is still ideal to use a screen 
with an aspect ratio that closely matches your likely source material. You can then more easily fill the screen 
with the image without restricting either image size or content. For example, standard video from a VCR has a 
4:3 ratio (approximately) and can fill a 4:3 screen without side-to-side stretching, whereas a high-definition 
signal with a 16:9 aspect is largest on a 16:9 screen.
 Figure 2-7  Aspect Ratios: Image vs. Screens
As shown in Figure 2-7, an obvious mismatch between source material and screen is characterized by black 
bars on both sides of the image (if the screen is wider than the source material) or above and below the image 
(if the source material is wider-typically called a letterbox display). 
Alternatively, if the area of unused pixels is considered minimal, you may prefer to use the projectors software 
control to slightly stretch the image either horizontally or vertically-enough to utilize the remaining pixels 
while not noticeably distorting the image.
Using a Cinema "Flat" Screen (1.85 aspect ratio)
By default, source signals closely matching the projectors 2048 x 1080 display area will fill this area 
accordingly. Signals with lower aspect ratios will automatically scale to be as large as possible while 
maintaining their original aspect ratio. For details on resizing behavior, refer to Section 3.6.3 Image Settings 
Menu.

Displaying both “Flat" and "Scope" 
As an example, two standard types of displays (flat and scope) differ in their width-to-height aspect ratio as 
shown below:
 
 Figure 2-8  Typical Wide Formats
Achieving either of these displays from a variety of incoming source material (that may or may not be in the 
same format) depends on proper settings in the projector as well as certain room conditions.
Projector Variables: Electronic and Anamorphic Resizing
The native resolution of the projector (1.89) closely matches the aspect ratio of flat source material (1.85). 
Wider scope material, however, may be squeezed electronically that is, it is distorted into a narrower area 
(characterized by unusually thin people) so that its pixels can then be stretched horizontally through the 
anamorphic lens to regain the full and properly proportioned 2.39 display. This optical widening can stretch the 
image by approximately 25%. See Figure 2-9
.
 
 Figure 2-9  Typical Method for Achieving “Scope”
Masking Options
In order to conveniently present different types of incoming data-for example, flat vs. scope-on a single screen, 
you can use physical masking to cover the unused edge(s) of the screen. These movable panels are most 
commonly installed along the top edge of the screen, changing the height of the screen, but not its width, and 
are most frequently used in permanent installations. 
The screen shown in Figure 2-10
 also has a bottom mask:
• Add masks for scope displays
• Remove masks for flat displays

Alternatively, masks may be installed at each side of the screen in order to change the width of the screen, but 
not its height.

• Remove masks for scope displays
In some cases, the room will have both side and top/bottom masking installed. This arrangement is the most 
flexible of all.

2.2.4 Ambient Lighting
The extraordinary brilliance of this projector is certainly 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.
2.2.5 Other Considerations
Other 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 that 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, 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 over-
all effect. A good rule of thumb is to be no closer than 1.5 times the width of the screen.

2.3 Projector Position and Mounting
Installation type, the available screen, and ambient lighting all affect where the projector should be 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 location of 
the projector for the chosen screen size.
2.3.1 Throw Distance
Throw distance is the distance between the projector and the screen (see Figure 2-13). For any installation, 
placing the projector at an accurate throw distance is necessary in order for the image size to closely match 
your screen. The farther the projector is from the screen, the larger the image. With zoom lenses, youll want to 
know the approximate minimum and maximum image sizes possible from a given throw distance so that the 
most appropriate lens is installed at the site (throw distance/screen width = throw ratio).
 Figure 2-13  Estimating Throw Distance: Example
NOTE:
 If your projector is slightly tilted in relation to the screen, typical for large venues and/or elevated 
installations, throw distance still represents the smallest measurement between the screen and projector.
As shown in Figure 2-13, the throw distance is approximately equal to the horizontal width of the screen 
multiplied by the type of lens you are using. For example, if you are using a 1:1 lens, proper throw distance 
will be approximately the same as screen width. Once you know your screen width and type of lens, you can 
estimate throw distance needed. Or, if you know throw distance, you can determine what images sizes are 
possible with a given zoom lens.

In this example, a throw distance of
18.75 feet will project an image
approx. 13-15 ft wide, depending
on the zoom setting.

Roadie HD+35K User Manual2-13020-100340-02 Rev. 1  (01-2010)
IMPORTANT! For proper placement in any installation, use the lens and screen size to calculate the precise
throw distance using the tables provided in the Dealer Section of the Christie Website, PN 020-
100395-xx. In addition, please keep in mind that due to lens manufacturing tolerances for lens
focal length, actual throw distance can vary ±5% or more between lenses described as having the
same throw ratio.
2.3.2 Vertical & Horizontal Position
Refer to the offsets shown in this section to help determine how high or low to install the projector in relation 
to the center of the screen, and/or how far off to one side. 
Vertical Position 
Describes the elevation of the projector in relation to the screen. For many typical rental/staging installations, 
the projector is mounted above screen center. An ideal vertical position helps to ensure that images are 
accurately rectangular in shape rather than distorted into a keystoned shape with non-parallel sides, that both 
image focus, and brightness remains optimized.
NOTE: Proper vertical position is recommended, although vertically keystoned images (i.e., those with sloping 
sides) can be corrected in software. Refer to 
Section 3 Operation.
The image can be offset vertically (shifted above or below lens center) by using the built-in keypad or the 
standard IR remote. Starting with no offset, the 2048 x 1080 image from this projector can be moved by a 
distance of up to ±100% of the image height (depending on the lens), resulting in the entire image being 
displayed above or below lens center. Refer to Figure 2-12
.
 Figure 2-14  Vertical Offset Range 
						

							2-14Roadie HD+35K User Manual020-100340-02 Rev. 1   (01-2010)
Section 2: Installation and  Setup 
NOTES: 1) Assumes full 2048 x 1080 display. 2) Recommended offset range can sometimes be exceeded, however 
this may affect image quality. 
3) Due to manufacturing tolerances, an offset range can vary ±5% or more 
between lenses described as having the same throw ratio, between projectors, and with any lens/projector 
combination. 4) Simultaneous horizontal and vertical offset can limit the adjustment range of each, as can 
long throw distances. 
ALTERNATIVE METHOD OF DESCRIBING VERTICAL OFFSET
Offset can also be specified as the distance traveled from lens center (such as 270 pixels) and expressed as 
a percentage (270 pixels=50%) of half of the image height. This concept of image movement is illustrated 
in the example below: 
 Figure 2-15  Example of Alternative Offset Specification
For any projector, if you find that you cannot raise or lower the image enough using mechanical vertical 
offset, try adjusting V-Position in the 
Size and Position menu when displaying at less than the minimum 
size (see Section 3.6.3 Image Settings Menu
). If images remain keystoned or exhibit uneven brightness, the 
projector may simply be too high or low in relation to the screen. Relocate for optimized performance.
Horizontal Position 
The image can be offset horizontally (shifted left or right of lens center) by using the built-in keypad or the 
standard IR remote. Starting with no offset, the 2048 x 1080 image from this projector can be moved by a 
distance of up to ±35% of the image width (depending on the lens).
