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.
Do not stack more than four projectors.
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 drop or jarr the projector.
The lens release lever should always be set to the locked position to

prevent the lens from falling out.
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.

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.

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).

W = width

H = height

D = diagonal (inches)

The example calculations below show how to convert diagonal sizes in inches into
width and height, at various aspect ratios.

2.35:1 (Scope)

W = D x 0.92in (D x .023m) H = D x 0.39in (D x .01m)

1.85:1

W = D x 0.88in (D x .022m) H = D x 0.47in (D x .012m)

16:9 = 1.78:1

W = D x 0.87in (D x .022m) H = D x 0.49in (D x .0125m)

Notes

1.66:1 (Vista)

W = D x 0.86in (D x .022m) H = D x 0.52in (D x .013m)

4:3 = 1.33:1 (native aspect ratio)

W = D x 0.8in (D x .02m) H = D x 0.6in (D x .015m)

5:4 = 1.25:1

W = D x 0.78in (D x .02m) H = D x 0.625in (D x .016m)

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 VIP 2000, 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.

any full width image, including:
4:3 1400 x 1050 pixels (native resolution)

1.66:1 (Vista) 1400 x 843 pixels
16:9 1400 x 788 pixels

1.85:1 1400 x 757 pixels

Notes

For more information about

Throw ratio factor (TRF), see
Useful lens calculations, later in
this section.

2.35:1 (Scope) 1400 x 596 pixels

A Throw ratio factor (TRF) of 1.07 has been applied to the following chart:

5:4 full height 1313 x 1050 pixels

Method two: by calculation

See the calculations, on the page immediately following the lens charts.
