Broadcast Key 
Enter a checkmark if you want keypad commands sent to any one projector to be 
relayed to all projectors in a serial network. Note that the 
Pr o j key will temporarily 
“override” the effect of a broadcast setting and allow you to control a specific 
projector when necessary. Make sure to remove the Broadcast Key checkmark when 
operating redundant networks. 
Backlight 
Toggle the built-in keypad lighting on/off. 
Front IR / Back IR 
As needed for your application, set to “on” so that the front and/or rear IR sensor 
locations on the projector responds to the IR keypad. Set to “off” to disable. 
To disable both IR sensors, you cannot use the IR remote keypad to select the second 
OFF setting. This safeguard prevents accidentally disabling an IR keypad while you 
are using it. Instead, use either the built-in keypad or a wired remote (optional) to set 
the remaining active sensor to 
OFF. The projector will no longer respond to an IR 
remote keypad. 
Wired Keypad 
Select “On” to enable use of a wired remote keypad connected to the rear of the 
projector. The projector will then respond to incoming commands from either port. To 
disable the wired keypad, you must use a different keypad—the built-in or an IR 
remote keypad—to select “off”. This safeguard prevents you from accidentally 
disabling the wired keypad during use. 
 
In the Configuration menu, select 
the Geometry and Color submenu 
when you need to modify overall 
color performance and/or image 
geometry for all sources. 
 
Test Pattern 
Choose the desired internal test pattern or select OFF to turn off a test pattern. 
Alternatively, use the 
Te s t key for cycling through test patterns. 
Vertical Keystone 
Use to correct a keystoned image shape in which both sides of your image are inclined 
toward the top or bottom edge. Keystone is typically caused by tilting the projector in 
relation to the screen, so that the lens surface and screen are no longer parallel to each 
other. (Figure 3.16.)   System Configuration

Brightness Uniformity — SUBMENU 
Brightness Uniformity provides further refinement of displays already matched for 
their primary colors and overall light output. Use Brightness Uniformity to create an 
exceptionally smooth image in which no area appears brighter and/or more red, green 
or blue than another. In the Brightness Uniformity menu, enable the “Uniformity 
Enable” checkbox to access a multitude of adjustments for critical color light output 
control in specific areas throughout the image. Your settings apply as long as the 
“Uniformity Enable” checkbox is enabled and you are using a “User” color 
temperature defined by the Brightness Uniformity controls. Remove the checkmark 
from the “Uniformity Enable” checkbox to disable the Brightness Uniformity 
function. 
NOTE: See also 3.10, Using Multiple Projectors for the complete step-by-step 
procedure for achieving uniform brightness in adjacent displays.  
Edge Blending 
— SUBMENU 
The Edge Blending submenu provides a range of controls for smoothing together the 
overlapping bright edges of multiple adjacent projected images to create a single 
larger “seamless” image.  
NOTE: See also 3.10, Using Multiple Projectors for instructions on adjustment. 
Color Adjustments by X/Y, and Color Saturation — 
SUBMENUS 
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color performance or 
“gamut”. Sometimes known as Comprehensive Color Adjustment™.  2) Factory-
measured primary color levels, which ensure a specific color performance from 
projector-to-projector, can be altered in the Service menu only. If you suspect 
alteration of these defaults, the factory settings can be recovered with selection of 
“Factory Defaults” in the Color Primary Settings submenu accessed via the Service 
menu (password-protected). 
From the factory, the projector can utilize 
any of the 3 pre-defined color performance 
settings identified at right (default=Max 
Drives), or colors can be driven on the 
basis of color temperature. For most 
applications, one of these options will 
produce accurate and realistic colors from 
a variety of sources. They can be applied at 
any time in the Advanced Image Settings 
menu (“Select Color Adjustment”), and are 
not adjustable.

Christie DS+60 User’s Manual     3-39  
DEFINING “USER” COLOR GAMUTS: In some cases, you may find that none of the pre-
defined “Select Color Adjustment” options exactly suit your needs. For example, you 
may require a unique color gamut (range) for a single projector or application, or you 
may need to precisely match colors across multiple adjacent displays. In such cases, 
use either the Color Adjustments by X,Y or Color Saturation submenu to define the 
precise hue of each primary color component (red, green, blue, and white) used to 
generate the millions of colors produced in displays. You can create up to four custom 
color gamuts (User 1, 2, 3, or 4) defined by these adjustments. 
Note that the two menus differ only in their user interface, so use whichever menu 
best suits your needs and application. 
• Color Adjustments by X,Y
 — Enter known x/y coordinates from the 
chromaticity graph. For best results, use with a color meter. 
• Color Saturation
 — Adjust color slidebars and judge image color by eye. A 
color meter can also be used. 
A user-defined color “adjustment” can be applied by selecting it in the Advanced 
Image Settings menu (“Select Color Adjustment”). 
NOTE: Defining a “User” color gamut when a test pattern is displayed does not get 
saved in the current channel. Display the source first then select a color gamut (User) 
from Select Color Adjustment. Changes here are then saved for that source in channel 
memory.  
COLOR ADJUSTMENT BY X,Y: Use 
this submenu if you want to alter, 
add or copy a color gamut (i.e., 
“color adjustment”). Controls in this 
menu define the precise hue of each 
primary color component (red, 
green, blue, and white) used to 
generate the millions of colors 
produced in displays. The x/y 
coordinates for each color define its 
location on the standard CIE 
chromaticity graph (see Figure 
3.19)—changing either or both of 
these numbers will change the hue of 
the color, and relocate the “triangle” 
for possible colors. For example, 
changing the x/y coordinates for red 
will either move the color closer to 
orange or closer to violet, which will in turn affect all displayed colors having a red 
component. Adjust the slidebars or enter new specific coordinates as desired to define 
or change up to four “User” color gamuts needed for your environment and 
applications. Apply the new User gamut at any time in the Advanced Image Settings 
menu.

here. 
PROCEDURE FOR X,Y ADJUSTMENTS:  See 3.10, Using Multiple Projectors. 
COLOR SATURATION: Use this 
submenu if you do not have 
specific color coordinates in mind 
and will simply judge color 
performance by eye. 
Adjust the hue of each primary 
color (red, green, blue, and white) 
by using more or less of it in 
relation to the other colors.

Test Pattern 
Choose the desired internal test 
pattern to display or select OFF to 
turn off a test pattern. 
Alternatively, use the 
Te s t key for 
cycling through test patterns. 
Test Pattern Gray Level 
Set the desired level of gray for 
displaying in the full gray field test 
pattern. 
Freeze Image 
Enter a check mark to freeze (stop) an image on a single frame. This diagnostic tool is 
useful if you need to examine in detail a still version of an incoming image that cannot 
be “frozen” at the source. For example, in moving images it is sometimes difficult to 
observe artifacts such as external deinterlacing/resizing and signal noise. Remove the 
checkmark to return back to normal. 
Color Enable 
Select which color or colors you want to see. This is useful while working with color 
temperature, input levels or other special setup parameters. Colors can also be 
enabled/disabled by entering the corresponding function code listed on the back of the 
standard remote keypad. 
Odd Pixel Adjustment 
NOTES: 1) Factory-set and rarely required by user. 2) Source must be >110 MHz. 
When using certain RGB sources, you may need to adjust the normal gain or offset of 
odd pixels in relation to even pixels. This will smooth out very narrow (1-pixel wide) 
“checks” or vertical stripes that indicate adjacent “on” and “off” pixels. Although 
offset and gain slidebars can be adjusted individually and manually, using the Level 
Detector simplifies this process (see Figure 3.21): 
1.  Use an external analog native-sized continuous grayscale test pattern with at 
least 256-levels. 
2.  Turn “Level Detector” on. 
3.  Set “Level Value” to ~200. The image should now be black-and-white (or 
black-and-one color, if you use “Color Enable” function). 
4. Adjust offset. Half of the pixels will move, the other half will not. 
5.  Adjust until the two transition regions overlap. The stripe of noise will be 
minimized, defined by the value in the slidebar. 
6.  Set “Level Value” to ~800. The image should now be black-and-white. 
7.  Repeat Steps 4 and 5, but adjusting gain. 
8.  Repeat Steps 3-7 for all remaining colors. Your RGB source should now be 
OK.   System Configuration

Figure 3.21. Using “Odd Pixel Adjustment” 
NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 
represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment 
eliminates “1 pixel on, 1 pixel off” patterns only, not any type of larger patterns. 
Color Wheel Calibration 
— SUBMENU 
The Color Wheel Calibration submenu allows you to set the timing of the two color 
wheels in the projector. It is important the color wheels are correctly calibrated for the 
colors and shades in the displayed image 
to appear the same. Incorrectly calibrated, 
the colors will appear in various 
unmatched shades throughout the image. 
This adjustment is typically only required 
when a color wheel is replaced. 
1.  Select the single lamp operation mode that corresponds to the color wheel you 
want to calibrate. For example, select “Single Lamp 1” when calibrating color 
wheel 1 and “Single Lamp 2” when calibrating color wheel 2.   
2. Enter the Color Wheel Calibration submenu – the Color Ramp test pattern will 
automatically display and the “Color Enable” option will automatically switch to 
White. 
3.  Adjust  “Color Wheel 1 (or 2) Delay” so the transitions across each color bar 
appears smooth. 
4.  Repeat Step 1 – Step 3 for the other color wheel. NOTE: Wait for 35 seconds 
when requesting a change in single lamp operation modes to allow for one lamp 
to warm up and the other to turn off. 
5.  Verify adjustments by choosing different colors in “Color Enable”.  
 
NOTES: 1) Upon entering the Color Wheel Calibration submenu, the “Color Enable” 
option automatically switches to white and the color ramp test pattern displays.

Peak Detector 
The “Peak Detector” is fast method of defining individual input levels, and can 
improve the accuracy of input levels set by the Auto Input Level function. Enabling 
the “Peak Detector” activates a special operating mode for detecting only pixels that 
are considered black or white—all other levels are displayed as a mid-level gray. 
When used with a 16-step grayscale pattern in which the two black and white bands 
are known to be at opposite edges of the image, you can watch these isolated areas 
while adjusting individual blacklevels and input drives until both bands are just 
visible. Images from this source will then display correct blacks and whites without 
crushing or washing out. 
Level Detector 
The “Level Detector” checkbox enables a specific thresholds for blacks and whites—
input levels that fall below a specified Level Value (see below) are displayed as black, 
and all others are displayed as white. It aids in Odd Pixel Adjustment. To use: 
1. Enable “Level Detector” and display a continuous grayscale. 
2. Set “Level Value” to near black (such as 200). 
3.  Adjust Offsets to minimize area of black stripe. 
4. Set “Level Value” to near white (such as 800). 
5.  Adjust Gains to minimize area of white stripe. 
Level Value 
The “Level Value” defines the value to be used by the Level Detector in recognizing 
blacks and whites. See Level Detector, above. 
 
The dual lamp illumination system used in this projector gives you the flexibility to 
choose an operation mode (single lamp or dual lamp) to suit the specific needs of your 
installation. The unique lamp auto-switching feature also provides the potential to 
operate the projector for extended periods without interruptions related to lamps or 
lamp replacement.  
A complete understanding of how the projector works is critical in effectively 
maintaining its continuous operation. The Lamp Menu and the options provided, such 
as selecting a lamp operation or power mode and monitoring lamp status can help in 
achieving bright, uninterrupted projection.  
About lamp operation, modes and auto-switching 
The projector by default is set to power on in Dual lamp mode. No light appears on 
the wall during the first 25 seconds of power up, as this is the time it takes to ignite 
the lamps. Brightness gradually increases as the lamps warm up to their full potential. 
Before sending a keypad command, wait for the projector to complete its initialization 
(“ON” appears in the status LED display), otherwise the request will be ignored. After 
this time, you can switch to a single lamp operation mode or make any other requests 
through software.  
On rare occasions, a lamp may not ignite on the first attempt.  
• In dual lamp mode, only the light from the lamp that ignited successfully is 
seen on the wall. The projector will then continue to strike the second lamp 
(waiting 90 seconds in between each attempt) indefinitely – the lamp operation 
3.7   The Lamp Menu  
						

							Section 3: Operation 
3-44   Christie DS+60 User’s Manual  
mode will not automatically switch to the single lamp mode. It is strongly 
recommended if after 5 minutes the second lamp does not ignite, you manually 
switch to a single lamp operation mode and replace the lamp that won’t strike.  
• In single lamp mode, the projector will try to strike the lamp again in 90 
seconds (considered re-strike #1).  Only after the third attempt (re-strike #2) 
will the projector declare the lamp as “Failed to Strike” (in Lamp submenu) 
and automatically switch to the single lamp operation mode for the lamp that 
was not ignited. All lamp specific menu options will then change to reflect the 
true lamp operation mode of the projector. 
NOTE: P-VIP lamps, by nature, do not successfully ignite when “hot” and 
therefore the 90 second wait period is taken by the projector before each strike 
attempt and between powering the projector down and up again.  
Lamp operation modes will also automatically change if there is a failure of one of the 
lamp related components, such as the lamp driver, color wheel or fan. An error code 
or failure message will be displayed in the status LED or through the RS-232 serial 
communications log that indicates which component has failed. The lamp status will 
also show one of several messages that points to the failed component. The lamp in 
this instance is typically still okay and does not require replacement.  
MANUALLY SWITCHING FROM DUAL TO SINGLE LAMP MODE – Switching from dual 
to single lamp operation mode occurs immediately. The result is an instant dimming 
of the displayed image. At this time, you can modify the lamp power or adjust other 
settings to increase desired brightness.  
MANUALLY SWITCHING FROM SINGLE TO DUAL LAMP MODE – When you manually 
switch from a single lamp mode to the dual lamp mode, the projector immediately 
tries to ignite the second lamp. If the first attempt to ignite the lamp fails it will wait 
90 seconds and try again.  This process will continue indefinitely. It is recommended 
you switch the lamp operation mode back to single lamp mode if the second lamp 
does not ignite after 5 minutes. 
MANUALLY SWITCHING BETWEEN SINGLE LAMP MODES – When manually switching 
between single lamp modes, there is a 35 second overlap when both lamps are on. 
This overlap allows the “new” lamp to warm up before the other lamp is turned off. 
The new lamp operation mode displays immediately in the menus. Only after the third 
attempt (re-strike #2), will an error message display to indicate the type of error that 
was detected. If no specific error is detected, then the error will be “Failed to Strike”. 
If this occurs, the first lamp will not turn off and the projector will continue to operate 
in the original lamp operation mode. In summary, it could potentially take the 
projector up to 4.5 minutes to successfully switch lamp modes. The projector will 
attempt to maintain light on the wall during this time. NOTE: If a problem is fixed 
before the last strike attempt the lamp could turn on. 
If a lamp fails during operation, the projector will immediately attempt igniting the 
other lamp if it’s not already on. Only in this case, will there be a brief interruption in 
the display. 
NOTE: A lamp will naturally decrease in brightness as it ages. Lamp life can also be 
decreased further by a frequent change in lamp operation modes (number of times its 
ignited).

Figure 3.22. The Lamp Menu 
LAMP MESSAGE  - Enter a checkmark to enable a warning message that will appear 
upon power-up when the lamp has reached the specified lamp limit and should be 
replaced. Delete the checkmark to prevent display of this message—instead, when 
your lamp expires, only the status display messages on the back of the projector will 
provide the visual warning to replace the lamp. 
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) If 
a lamp warning message appears during power-up, press 
Ex i t to temporarily cancel 
the message. The message will continue to appear upon power-up until you install a 
new lamp. 
LAMP LIMIT  - Set the lamp limit to the number of hours you expect to log on the 
current lamp before replacing it. The limit by default is 1500 hours. 
LAMP MODE - Select a lamp mode to control the light output of your projector — 
select “Max Brightness” to run the lamp as brightly as possible or “Power
”  (default) 
to continually run the lamp at the specific wattage set by adjusting the 
POWER 
slidebar.  
POWER – Adjust the slidebar when LAMP MODE is set to “Power”, to indicate the 
number of watts (250-300) applied to the lamp.
 In general, a lower power level 
generates a dimmer image. Specifying a maximum power level is the same as 
operating in “Max Brightness” mode. 
LAMP OPERATION – One of the key features of the projector is that it can be operated 
with one or two lamps on. From the pull down list, select the lamp operation mode 
you want to operate the projector in. “Dual Lamp” is the default. 
• 
DUAL LAMP – Select “Dual Lamp” to operate the projector with both lamps 
on. In this mode, you can achieve maximum brightness output by the 
projector. If one lamp fails in this mode, an immediate dimming of the display 
occurs and the projector will continuously attempt to turn the second lamp 
back on – it will not switch to a single lamp operation mode. If the projector 
fails to turn the lamp back on after 5 minutes it is recommended you manually 
switch lamp operation to single lamp for the lamp that is working. If both 
lamps fail at the same time, an error is reported and the projector 
automatically powers down.   
						

							Section 3: Operation 
3-46   Christie DS+60 User’s Manual  
• SINGLE, LAMP #1 OR SINGLE, LAMP #2 – Select “Single, Lamp 1” or “Single, 
Lamp 2” to specify which lamp to operate the projector with. The other lamp 
remains in “reserve” and will only turn on if the current lamp “fails” for some 
reason or if the mode is manually selected.   
NOTES: 1) The projector will automatically shutdown if it detects both lamps 
have “failed” (this includes lamps not installed). 2) The lamp operation mode 
will not automatically switch to a previous mode once a “failed” lamp is 
replaced. It must manually be selected. 3) It takes approximately 25 seconds 
for a cold lamp to reach full brightness when it is first turned on. 4) Power is 
cut to a lamp only when the lamp operation mode is switched to the other 
lamp. IMPORTANT  - the original lamp stays on for 35 seconds to allow the 
new lamp to warm up before power is cut and lamp operation modes change.  
MORE LAMP 1 (MORE LAMP 2) - There are two separate lamp submenus that can be 
accessed from the Lamp menu. Each submenu is dedicated to one lamp – you can 
view specific lamp information, such as lamp hours, lamp history and the current 
status of the lamp. You can also change lamp operation modes.
 
LAMP HOURS  
 - This read-only information shows the current number of hours 
logged on the current lamp. Whenever a new lamp serial number is detected it begins 
to log time for the new lamp. This information also appears in the Status menu. 
LAMP S/N  - This read-only information displays the serial number for the current 
lamp. NOTE:When a lamp is installed, the projector automatically detects the serial 
number and displays it here. The serial number is not manually entered. 
LAMP 1 (OR 2) STATUS – This read-only information displays the current status of a 
lamp and can be viewed any time during operation. Refer to the list below for the 
possible lamp status messages and their meaning: 
•  
“Good” – displays continually during operation until there is a failure with the 
lamp. 
• 
“Failed to Strike” – displays when the projector cannot turn a lamp on. This may 
or may not be lamp related.  
• 
“Lamp Not Installed” – displays when a lamp isn’t installed. If a lamp is present 
check that the lamp is fully connected to the terminal block. 
• 
“Turned Off Unexpectedly” – displays when a lamp or lamp related component 
fails –  may be caused by a hot lamp, failed lamp or a lamp driver problem. 
Check for error code on LED status display. 
• 
“Interlock Tripped”- displays when the lamp door is opened for a lamp that is 
still on. The lamp is automatically turned off. 
• 
“Cooling Fan #8 (or #10) Failed” – displays when a lamp fan fails  (Cooling fan 
#8 associated with Lamp #1 and Cooling fan #10 with Lamp #2). 
• 
“Color Wheel Stopped” – displays when a color wheel stops operating. 
• 
“Driver Vcc too Low” – displays when a lamp driver fails.
