INSTALLATION OVERVIEW
Installer’s Experience Level
The PRO895X is a sophisticated Entertainment
MachineTM. In addition to making the necessary
connections, installation will most likely require
a series of adjustments to ensure the projected
image is not distorted. If these adjustments are not accu-
rate, the operation of the PRO895X could be adversely
affected. For this reason, installation and setup should be
performed by a qualified service person and should con-
form to all local codes. The installer must also adhere to
the pertinent Articles of the National Electrical Code (NEC),
pertinent Regulations of the Federal Communications
Commission (FCC), and all relevant codes of local regulat-
ing agencies.
National Power Cord Requirements U.S. / Canada
• The power cord must be UL listed and CSA certified.
• The minimum specifications for the power cord are as
follows: No. 18 AWG, Type SV or SJ, 3 conductor.
• The power cord must have a rated cur-
rent capacity of at least 10 amperes.
Installation Considerations
Before you install the PRO895X...
Standard North
America (120 VAC)
• The attachment plug must be an
earth-grounding type with a NEMA 5-15P
(15A, 125V) or NEMA 6-15P (15A, 250V)
configuration.
Ventilation -- Proper ventilation keeps the
PRO895X running cool. Air circulates through
perforations on the sides of the cabinet. Do not
block these vents or you will shorten the life of
the PRO895X.
Power Cord -- The PRO895X has a three-wire
grounding-type plug having a third (grounding)
pin. This plug will only fit into a grounding-type
power outlet.
North America
(240 VAC)
Other Countries
• The cord set fittings must bear the
certification mark of the agency responsible for evaluation
in a specific country. Acceptable agencies include the fol-
lowing:
BSI (United Kingdom)
CEBEC (Belgium)
DEMKO (Denmark)
EANSW (Australia)
SETI (Finland)
Nemko (Norway)
OVE (Austria)
SEMKO (Sweden)
SEV (Switzerland)
UTE (France)
This is a safety feature. If you are unable to insert the
plug into the outlet, contact an electrician to replace the
obsolete outlet. Do not defeat the safety purpose of the
grounding-type plug.
Power Source -- The PRO895X is designed to
operate on standard current, 120 volt 60 Hertz
AC or 230 volt 50/60 Hertz AC. Do not attempt
to operate it on DC current.

PRODUCT OVERVIEW
The PRO895X HD Projection Display system is a high reso-
lution multiple signal format display monitor. It uses 7”
high performance liquid cooled CRTs. Each CRT has a 5”
cannot be altered in the field. Each preset format has a
custom memory location to store customized setup data.
Each customized setup has a separated memory location
active phosphor area and a 90 degree deflection angle. The for each aspect ratio (4 X 3, letter box, compressed, and
CRTs use high-resolution color corrected multi-layered
hybrid lens assemblies.
16 X 9). You must set up and converge the system for each
aspect ratio that will be used. The five customer memory
locations are for signal formats that do not match the ten
factory preset signal formats. There is also the option to
copy the stored format data from one memory location to
another. This allows faster setup when several similar for-
mats are used. Internally generated signal patterns also
aid with setup of convergence. The internal pattern gener-
ator may sync from the internally preset signal formats or
it will sync from an external signal source. This is helpful
for on-site full convergence or just a touch up. You must
use the customer’s signal source to perform blanking and
phase adjustments.
Horizontal scan frequency is from 15 to 40 KHz. Vertical
scan frequency is from 40 to 100 Hz. Video system signal
bandwidth is 35 MHz. The projected display diagonal size
(4:3 aspect ratio) is adjustable from 60” to 240”.
Supported signal formats include NTSC (3.58 and 4.43),
PAL (M,N,B, and G), VGA, Mac II, and Grand Alliance HDTV.
Signal input options include 5 BNC connectors (R,G,B,V,H),
composite video, S-Video (Y-C), and an RS232 serial data
port. The IR control format is addressable (0 - 99) for use
with multiple unit installations. Each PRO895X comes with
a Universal customer remote control and a service/align-
ment 5-function MBR3470 remote control.
The PRO895X cabinet is comprised of three pieces.
Removal of the case allows full maintenance access to the
systems electronic and mechanical assemblies. Front and
rear mounted IR detector assemblies allow almost no inter-
ference to IR control. There are adjustable (and removable)
feet on the bottom of the case.
From the factory, the PRO895X comes aligned for a 80”
wide display. The preset projection distance is 96 3/8” and
configured for a ceiling mount. You may customize the
setup to be floor or ceiling mounted and rear or front pro-
jected. Refer to the setup section before attempting an
installation.
CABINET REMOVAL
Note the location of the screws which need to be removed
to allow access to the components.
Caution:
The convergence system is a digital controlled analog sys-
tem with 10 signal format preset and 5 customer option
memory locations. The preset format memory locations

SETUP MODE NOTES AND CAUTIONS
1. When you enter the setup mode, the system is in the
changes, press the “Quit” key twice.
“Geometry Mode” (the shape controls adjust all three
colors at the same time). To adjust an individual color
(i.e. Red to adjust SKEW), you must press the “Red”
key. This will put the system into the “Convergence
Mode” (the shape controls adjust one color at a time).
To return to the Geometry Mode, you must press the
“Red” key a second time.
8. Caution - shut all the PRO895X timers and signal source
power conserve features off before starting
convergence. If the video signal is lost, you will quit
convergence mode with no chance to save your work.
9. To display the Forced Mode Menu press “SETUP” and
“GREEN SELECT”.
10. To display the current sync and video format being used
press, “GREEN MUTE”.
2. When you are adjusting all colors (“geometry mode”),
the little arrow keys at the bottom are for video phase
adjust only. When they are pressed, the remote will
switch the geometry control to phase. If the arrow keys
have not been touched for a few seconds, the remote
will automatically switch back to the geometry control
you were last using before using the small arrows.
11.To see the elapsed time display, press and hold “LIN
C/LI-LIN”, until the regular menu disappears, and then
press the “TIMER” or “H-Pulse” key.
12.To set the unit IR Code (for use when multiple units are
in the area), press and hold “LIN C/LI-LIN”, until the
regular menu disappears, and then press “T/LS”, “T/LS”,
“T/LS”, “T/LS”, and “ADJ TOGGLE”.
3. When you are adjusting an individual color (“conver-
gence mode”), the little arrow keys at the bottom are
for DC Centering only. When they are pressed, the
remote will switch the convergence control to DC
Centering. If the arrow keys have not been touched for
a few seconds, the remote will automatically switch
back to the convergence control you were last using
before using the small arrows.
13.Copying Formats Procedure
Copy the setup information (Convergence, blanking,
phase, chromatics, and aspect ratio) from one defined
format to another defined format. The procedure quickly
copies unrecognized new formats or existing formats to
one of the five available “Customer” defined format
spaces. The ten factory format presets cannot be over-
written. To display the Copy Format Menu, press
“R-MUTE”. Use the Left/Right arrows to select the for-
mat you want to copy. Use the Up/Down arrows to
change the menu option from “Copy From” to “Copy To”.
Use ENTER to initiate copying the format to the newly
specified customer format (Customer 1, Customer 2,
etc.) If a format already exists in the selected Customer
format space, it will be overwritten by the new format
when ENTER is pressed. QUIT exits the menu without
making any changes.
4. The setup controls, in the on screen display, are usually
labeled with Horz/Vert, T/L (top/left), or B/R
(bottom/right) and a number value indicating the
current setting.
5. If you want to see what effect the “new setting”
compared to the “stored setting” has on the display,
press the “ADJ TOGGLE” key on the remote. Adjust tog-
gle will allow you to switch between the two settings
before committing to a change.
6. After making your changes and adjustments, be sure
you SAVE THE NEW SETTINGS. If a major change has
been made, new module, new CRT, or a change in the
physical setup, you must re-adjust and store the
geometry/setup for each of the formats and aspect
ratios being used.
14. To aid with the alignment procedure, it is recommended
that you mark the center of the screen and the center
of all four sides with masking tape. Use “drafting” type
tape that will not leave any marks. This will give you
calibration points for convergence and CRT alignments.
7. To escape from the setup mode without saving any

SCREEN SIZE SELECTION
Courtesy of Draper Shade & Screen
Note - Vertical presentation of a slide reverses its aspect ratio. To
allow this, use a 1.00: 1.00 aspect ratio for any type slide.
One of the most important decisions in screen selection is to
determine the correct size of screen based upon-
Projection Formats
1. The dimensions of the audience area.
2. The projection format, or formats, to be used.
Most models of DRAPER screens are offered in both audio visual
and 3:4 video formats. Certain models are also offered in HDTV
and WideScreen formats. The differences between these formats
are stated below.
In some situations, these two questions yield the same answer; in
others they do not and compromises must be made. Here are the
key considerations:
We are glad to provide any DRAPER screen in the size and projec-
tion format of your choice. We can provide any size up to and
including the largest published size. If you do not find the size
and format you need listed, please call or fax your requirement to
us, and we will be delighted to quote.
Audience Area-In determining the correct size of screen in rela-
tion to the audience area, the goal is to make the size large
enough so those in the rear of the audience area can see the sub-
ject matter easily, but not so large that those in the front of the
audience area have difficulty seeing the full width of the project-
ed image.
Audiovisual (or AV) format screens are intended for general use.
They accommodate a variety of projector types and range from
square to wide horizontal in aspect ratio.
Width-The generally accepted guideline in determining the screen
width is the Two and Six Rule:
A. Screen width should equal the distance from the screen to the
first row of seats, divided by two.
AV format screens are described in terms of height x width, and
are standardly furnished without black borders, although borders
are optionally available.
B. Screen width should equal the distance from the screen to the
last row of seats, divided by six.
Video format screens, on the other hand, are specifically
designed for use with video projectors. Their format is strictly
defined as a 3:4 rectangle, and the size is usually described in
terms of a nominal diagonal. Conventional models of video format
screens are standardly furnished with black borders to frame the
image on all four sides, allowing for video projector overscan. Tab
Tensioned electric screens are routinely furnished with black bor-
ders at the sides and bottom, although black masking at the top
is optionally available.
In case of a difference between these two guidelines, the one
yielding the larger size should prevail.
Height-As a rule of thumb, the screen height should equal or
exceeding the distance from the screen to the last row of seats,
divided by eight. Ceiling height and projection format considera-
tions may modify this standard.
Ceiling Height-The bottom of the screen should be approximately
48” above the floor to allow all members of the audience to see
the bottom of the projected image.
HDTV format (9 high by 16 wide) is also available for high-defi-
nition television projection, Anamorphic Video and Wide Screen
format (1: 1.85).
Projection Format-Once you have determined the correct size of
the screen based upon the audience area, that size may be based
upon the type, or types, of projection equipment to be used. If
the screen will only be used with one type of projector of (over-
head projector, CRT video projector, etc.), it is easy to determine
the exact screen dimensions based upon the projection format of
How to Calculate a Custom Size
Draper also manufactures custom size screens to meet your speci-
fication. Virtually any size within the maximum shown for a given
model is available. Please call for pricing on special sizes. If you
need to calculate a custom size, these formulas may be useful (D

ratio, which is the relationship of the height of the projected
image to its width. Aspect ratios of common projection formats
are listed below.
3:4 Video:
H = D x.6
If it is necessary to modify the screen dimensions based upon the
formats of projectors to be used, it is preferable to hold the
screen height constant and increase the screen width as neces-
sary, rather than to hold the width constant and decrease the
height.

SETUP AND ALIGNMENT PROCEDURE
c. Set Blue CRT point angle according to the display width.
PROCEDURE OVERVIEW
Refer to the figures on page 20.
There are several situations to consider when performing the setup
procedure for the PRO895X System. The setup procedure will vary
depending on the required physical and signal configuration.
Note: The PRO895X unit is shipped with spacer shims between
the CRT and lens assemblies, these must be removed to set up the
“Scheimpflug (spring/edge)” focus. Refer to the figure on page 23
for the edge focus procedure.
The simplest setup is that of a “factory configured” projector
which will use the preset conditions. Factory configured means it
has been aligned for ceiling/front projection and a 80” wide dis-
play at a projected distance of 96 3/8”. (See pages 20 and 21.) In
this case, using the customer’s signal source, only minor blanking,
phase, and convergence touch up is required.
4. Mount the projector system.
Mount the PRO895X system according to the prearranged plans
agreed upon between the installer and end user. Verify the mount-
ing point, hardware, signal connections, and power connections.
If the display size is changed, to other than 80” width or the unit
is to be floor-mounted, completion of the full setup procedure is
required.
Note: It is recommended that preliminary setup be done on the
floor before hanging a ceiling-configured system.
5. Projector/Display Surface Physical Setup
a. Set the projector to screen distance according to display
width. Refer to the figures on pages 20 and 21.
b. Set projector height according to display size. Refer to the
figures on pages 20 and 21.
Setup, after a hardware repair, is the other condition.
Replacement of a CRT usually requires minor alignment steps
(yoke, astigmatator, focus, and re-convergence only for that
color). Replacement of modules, in the vertical, horizontal deflec-
tion, or convergence systems, usually requires that most all align-
ment steps are to be performed.
c. Adjust the projector’s position for no horizontal skew to
the display screen.
d. Verify that the Green CRT center is centered to the screen
horizontal center.
e. Stabilize the projector and screen mounting hardware.
f. Verify that the setup of steps “a” through “d” has not
changed.

III. PRELIMINARY ALIGNMENT SETUP
Floor: Red = -30; Green = -20; Blue = -30.
Ceiling : Red = 30; Green = 20; Blue = 30.
The following procedures are intended for complete
“Geometry/Convergence” setup. Use the customer’s signal for
doing phase, and size adjustments. You can use the internal
patterns for shape and convergence if the customer signal
sources do not have a cross-hatch pattern.
c. In geometry mode and convergence mode (green, red, and
blue) set “SKEW” H = 0 and “SKEW” V = 0.
d. Adjust the Red, Green, and Blue yokes for no horizontal
tilt or twist.
If you are realigning a single CRT, due to replacement, or doing
alignment touch up, perform the following steps as needed.
2. Yoke Ring Magnet and Astigmatator Alignment
Verify Only - This is not a normal field adjustment.
1. Yoke Tilt Alignment
The astigmatator assembly should be mounted 62.5 mm from
the video output module (from the front edge of the video out-
put module to the six pole rings). Refer to figure on page 24.
Use a cross-hair or cross-hatch pattern. Monitor only the cen-
ter- most horizontal line of the pattern to check yoke tilt.
Do not use SW9501, on the 9-1510 module, to disable conver-
gence. The vertical circuit is not disabled, only the horizontal is
disabled.
Astigmatator Alignment Verification Test
Adjust for the best electrical and mechanical focus.

h. Verify spot alignment by rotating Green electrical focus slightly
CW to CCW. The Dot shape should not tail or flair. The bright
area should remain in the center of the haloed area.
i. Repeat steps “c” thru “h” as needed to obtain the smallest and
best round Green center dot with no shape flaring.
j. Adjust for the best electrical and mechanical focus.
k. Repeat steps “c” - “j” for the Red and Blue displays.
l. Exit forced mode 6 and return to normal video. Set
Brightness and Contrast to 50.
Verify spot alignment by rotating Green electrical focus slightly
clock-wise to counter clock-wise. The Dot shape should not tail or
flair. The bright area should remain in the center of the haloed
area. Refer to the figure below.
Note: The yoke adjustments should not be touched during the
remaining setup steps.
FOCUS PROCEDURE USING SPRING SYSTEM
Changing Preset 80 inch Width Image Screen Size
Note: The PRO895X is shipped preadjusted for an 80 inch project-
ed screen size image.
To set up a screen size other than 80 inch width, you must
remove the shims from each of the 3 lens assemblies.
Note: Remove AC Power. Be careful not to damage
the lens assembly or scratch the lens surface. The
lenses can be easily damaged during removal and
reinstallation.
1. Each 80 inch width image focus shim (shown below) can be
removed from each lens by first loosening and removing the 4-
lens mounting screws, in the order shown below.
2. Carefully remove the lens assembly, remove, and discard shim.
If this test shows a need for astimatator alignment perform steps
“a” - “l” below.
Astigmatator Alignment Procedure
a. Set the display/sync mode to Forced Mode 6 (HDTV33) and
select a cross-hatch or dot pattern.
b. Cut off Red and Blue video or cover the CRT lens
assemblies.
c. Set Green electrical focus slightly CCW. This is to make a dot
near the display center dimly haloed with a bright center. The
haloed effect will also be visible with the cross-hatch lines.

d. Use the astigmatator 4-pole magnet to shape the halo and
bright spot as round as possible.
e. Use the astigmatator 6-pole magnet, if needed, to help shape
the halo and spot round.
2
f. Use the astigmatator 2-pole magnet (refer to the figure at
bottom left of this page) to center the bright spot within the
halo. You may also use an intersection, of the cross-hatch, to
center the bright area within the haloed area.
g. Use the main yoke magnets to position the signal raster center
to the CRT face center. Refer to figure below.
3. Reinstall lens using the screw installation sequence shown
above; hand-tighten the screws.
4. Follow the same procedure to remove the two remaining lens
shims.
5. Tighten and adjust the lens mounting screws following
the instructions described in the following section.

m. Turn off the sync forced mode 9 and return to normal video
viewing or sync forced mode 11.
4. Rough Geometry/Convergence Setup of Green
When aligning Green, some controls are enabled in Geometry only.
This is why the alignment starts by using Green in the geometry
mode of setup.
a. Using the setup remote control, press “SETUP” and “RED”.
This will put the system into the “GEOMETRY MODE”.
b. Using the setup remote control press “RED MUTE” and
“BLUE MUTE”. You should see only the Green video.
c. Roughly set up the shape of the Green display using the
appropriate Skew, Bow, Key, etc. controls. Adjust size, or
phase using the customer’s video signal. Refer to pages 25,
26, and 27 for the convergence remote control and
procedure notes.

procedure must be completed as part of the system mechanical
focus procedure. See the figure above.
a. Turn on the projector, project a cross-hatch pattern on the
screen. Cover up both the Blue and Red lenses. Work only on
the Green lens.
b. Tighten all 4 lens mounting screws.
c. Loosen all 4 lens mounting screws 3 full turns.
d. Adjust the mechanical and electrical focus to get the best
image possible in the center of the picture.
5. Rough Geometry/Convergence of Red and Blue
e. Loosen the lens focus adjustment knob. Fully extend the lens
barrel. Adjust mechanical focus while observing the center
horizontal line. Adjust until one side (left or right) comes
sharply into focus. Adjust the two screws opposite the side
that is in focus (i.e., if the left side of the center horizontal
line is in focus, adjust the two screws on the right side of the
lens). Turn each screw 1/4 - 1/2 turn at-a-time in the same
direction (in or out) while observing the focus of the center
horizontal line. If the sharp focus begins to move towards the
center of the image, you are going in the wrong direction (in or
out). Adjust in the correct direction until the entire line
achieves a uniform soft focus from left to right. You should
then be able to adjust the barrel focus to get the center
horizontal line sharp all the way across. If not, you can fine
adjust with this same procedure.
f. Loosen the lens focus adjustment knob. Fully extend the lens
barrel. Adjust mechanical focus while observing the center
vertical line. Adjust until one side (top or bottom) comes
sharply into focus. Adjust the two screws opposite the side
that is in focus (i.e., if the bottom of the center vertical
line is in focus, adjust the two screws on the top of the
lens). Turn each screw 1/4 - 1/2 turn at a time in the same
direction (in or out) while observing the focus of the center
vertical line. If the sharp focus begins to move towards the
center of the image, you are going in the wrong direction (in or
out). Adjust in the correct direction until the entire line
achieves a uniform soft focus from top to bottom. You should
then be able to adjust the barrel focus to get the entire image
a. Using the remote control, return to the SETUP Mode and
select the internal cross-hatch pattern.
