General precautions
Do not open the cabinet. There are no user serviceable parts inside.
Use only the power cable provided.
Ensure that the power outlet includes a Ground connection, as this
equipment MUST be earthed.
Take care to prevent small objects such as paper or wire from falling
into the projector. If this does happen, switch off immediately, and have
the objects removed by authorised service personnel.
Do not expose the projector to rain or moisture, and do not place any
liquids on top of the projector.
Unplug before cleaning, and use a damp, not wet, cloth.
Do not touch the power plug with wet hands.
Do not touch the power plug during a thunder storm.
Handle the power cable carefully and avoid sharp bends. Do not use a
damaged power cable.
There are no user-serviceable parts inside the lamp module. The whole
module should be replaced and returned to Digital Projection for re-
furbishment.
Notes
Take care when removing the lamp module, as it is heavy (>10kg).
Take care not to touch the glass surface of the lamp module. If you do
accidentally touch the glass, it should be cleaned before use.
Do not use the lamp for more than 750 hours, as this may cause
serious lamp failure, damage the lamp module and cause extra cost on
replacement.
Xenon lamps produce high intensity light. Do not look directly at the
light coming from the lamp housing, or the lens, or allow items such
as magnifying lenses to be placed in the light path. This could result in
serious eye damage.
Do not touch the ventilation outlets, as they will become hot in use.
Do not cover the ventilation outlets or inlets.
Do not cover the lens whilst the projector is switched on. This could
cause a fi re
Always allow the projector to cool for 5 minutes before switching off
the power, moving the projector or changing the lamp.
Never use strong detergents or solvents such as alcohol or thinners to
clean the projector and lens.

Installation precautions
Connect the LAN cable only to a computer LAN connection. Other
similar connectors may have a dangerously high voltage source.
The projector must be installed only by suitably qualifi ed personnel, in
accordance with local building codes.
The projector should be installed as close to the power outlet as
possible.
The power connection should be easily accessible, so that it can be
disconnected in an emergency.
Ensure that there is at least 30cm (12in) of space between the
ventilation outlets and any wall, and 10cm (4in) on all other sides.
Do not install the projector close to anything that might be affected by
its operational heat, for instance, polystyrene ceiling tiles, curtains etc.
The projector weighs over 100kg (200lbs). Use safe handling
techniques when lifting the projector.
When stacking projectors, the stack MUST be vertical, to ensure that
the stresses are distributed to all for frame couplings.
Before installation, make sure that the surface, ceiling or rigging that is
to support the projector is capable of supporting the combined weight
of the projector and lens (see specifi cation for exact weights).
Notes
±12°
Separate backup safety chains or wires should always be used for each
projector.
Do not place heavy objects on top of the projector chassis. Only
the rigging frame is capable of withstanding the weight of another
projector.
Do not stack more than four projectors.
Do not drop or jarr the projector.
Place the projector in a dry area away from sources of dust, moisture,
steam, smoke, sunlight or heat.
Do not tilt the projector more than ±12° from side to side when in use,
as this may cause serious lamp failure, damage the lamp module and
cause extra cost on replacement. The projector my be tilted forwards
and backwards as necessary.
Each time a new lens is fi tted to the projector, the calibration procedure
must be carried out. See Lens menu, in Section 4. Using the menus.
The zoom drive mechanism should always be set to the engaged
position, even when using the non-zoom lens, as it provides an extra
level of protection, should the lens release lever fail.

Screen requirements
Aspect ratio
Fitting the image to the DMD
If the source image supplied to the projector is smaller than 1400 x 1050 pixels,
then the image will not fi ll the DMD. The following example shows how a number of
common formats may be displayed without the use of an external scaling processor.
1400 pixels
1400 x 788 (16:9)
1400 x 757 (1.85:1)
1400 x 596 (2.35:1)
1313 x 1050 (5:4)
1050 pixels
Notes
The resolution of the DMD fi tted
to the projector is 1400 x 1050
pixels.
This projector does not perform
any image processing - the
MMS 1000 is recommended for
this purpose.
Diagonal screen sizes
Screen sizes are sometimes specifi ed by their diagonal size (D) in inches. When
dealing with large screens and projection distances at different aspect ratios, it is
more convenient to measure screen width (W) and height (H).
The example calculations below show how to convert diagonal sizes in inches into
width and height, at various aspect ratios.
W = width
H = height
D = diagonal (inches)
2.35:1 aspect ratio
W = D x 0.92in (D x .023m) H = D x 0.39in (D x .01m)
2048x1080

Fitting the image to the screen
It is important that your screen is of suffi cient height and width to display images at
all the aspect ratios you are planning to use.
Use the conversion chart, or the sample calculations below to check that you are
able to display the full image on your screen. If you have insuffi cient height or width,
you will have to reduce the overall image size in order to display the full image on
your screen.

Positioning the screen and projector
For optimum viewing, the screen should be a fl at surface perpendicular to the fl oor.
The bottom of the screen should be 1.2m (4 feet) above the fl oor and the front row
of the audience should not have to look up more than 30° to see the top of the
screen.
The distance between the front row of the audience and the screen should be at
least twice the screen height and the distance between the back row and the screen
should be a maximum of 8 times the screen height. The screen viewing area should
be within a 60° range from the face of the screen.
Notes
The projector should be
installed as close to the
power outlet as possible.
The power connection should
be easily accessible, so that
it can be disconnected in an
emergency.
Ensure that there is at least
30cm (12in) of space between
the ventilation outlets and
any wall, and 10cm (4in) on
all other sides.
Do not install the projector
close to anything that
might be affected by its
operational heat, for instance,
polystyrene ceiling tiles,
curtains etc.
The image can be fl ipped for
rear projection (see section
4. Using the menus, Image
menu) and displayed without
the need for extra mirrors or
equipment.
However, you must ensure
that there is suffi cient distance
behind the screen for the
projector to be correctly located.
Rear installation is generally
more complicated and advice
should be sought from your
local dealer before attempting it.

Choosing a lens
A number of lenses are available for use with the projector. Which lens you choose
will depend on the screen size, image aspect ratio and projection distance.
If you are simply connecting the output of a camera or computer directly to the
projector, then the image size (in pixels) may well be fi xed. If, however, you are
using commercially available image processing equipment, such as the Digital
Projection MMS 1000, you may be able to resize the image to fi t the DMD.
If the image does not fi ll the full width of the DMD, this effectively increases the
throw ratio of the lens. This can be corrected for by applying a Throw ratio factor.
Method one: using the lens charts
For the screen sizes listed below, use one of the charts on the following pages, to
choose a lens.

4:3 1400 x 1050 pixels (native resolution)

Choosing a lens by calculation
For any screen size not listed above, or if you need to be more precise, then use the
calculations below.
Identify actual width of the image in pixels.
•
Calculate the Throw Ratio Factor: TRF = DMD width (1400)
•
Image width in pixels
Identify the screen width required.
•
Identify the throw distance required.
•
Throw distance calculations are based on the distance from the outer end of the
lens, which will vary from lens to lens. Once a lens has been chosen, the fi gures
can be checked using the lens extension values given on the next page.
Calculate the throw ratio required. Throw ratio = Throw distance
•
Screen width x TRF
Choose a lens with the required throw ratio.
•
Check from the lens charts or the specifi cation (see section 6. Appendix), that
the lens chosen has a suffi cient throw range.
example
An unresized image, 1280 x 1024 pixels, screen width 8m, throw distance 25m
•
from the outer end of the lens.
Notes
The Throw ratio for a particular
lens is fi xed, but assumes that
the image fi lls the width of the
DMD.
For images that do not fi ll the
width of the DMD, the Throw
ratio is effectively increased.
To correct for this in these
calculations, a Throw Ratio
Factor (TRF) is used.
The lenses available and their
part numbers are listed below:

Useful lens calculations
The following lens calculations may be useful:
Throw ratio = Throw distance
Screen width
Throw ratio factor (TRF) = DMD width in pixels = 1400
image width in pixels image width in pixels
Therefore:
Screen width = Throw distance (from outer end of lens)
Throw ratio x TRF
Throw distance = Screen width x Throw ratio x TRF
The throw distance calculated above is to the outer end of the lens. For each lens,
the nominal distance between the front of the projector and the outer end of the lens
(lens extension) will be as listed below:
Notes
The Throw ratio for a particular
lens is fi xed, but assumes that
the image fi lls the width of the
DMD.
For images that do not fi ll the
width of the DMD, the Throw
ratio is effectively increased.

calculations, a Throw Ratio
Factor (TRF) is used.

Notes
Each time a new lens is
fi tted to the projector, the
calibration procedure must
be carried out. See Lens
menu, in Section 4. Using the
menus.
Be careful not to scratch
the lens surfaces. If you do
accidentally touch a lens, then
clean the surface using a lens
paper.
The zoom drive mechanism
should always be set to the
engaged position, even when
using the non-zoom lens, as
it provides an extra level of
protection, should the lens
release lever fail.
