Safety Warnings
All the safety warning in this manual are in bold italic type and can be identified by
the symbol shown on the left.
A list containing all the warnings is given below. It is recommended that time is
taken to study these before installing or operating the projector.
The customer should never attempt to disassemble the lamp from its housing or to
dispose of it other than by returning it to Digital Projection.
The condenser system is precisely aligned in the factory and no attempt should be
made by the customer to adjust it.
Only use lenses specified in this manual or recommended by Digital Projection.
High Voltage, Danger of Death - the arc lamp power supply has a 30kV strike
pulse mechanism, which is active during lamp switch-on.
Do not move or tamper with any seals or ducting panels on the projector or the
air flow could be disrupted and cause the projector to overheat. Always keep the
air inlets and outlets clear of any obstruction.
If the Air Filters are not regularly replaced the air flow inside the projector could
be disrupted and cause overheating. Overheating may lead to the projector shut-
ting down during operation
The projector should never, under any circumstances, be mounted or operated
upside down or at an angle greater than 90° from horizontal.
Never mount the projector near air conditioning or heating ducts, electrical
wiring or any materials which could be affected by the projector's operational
heat i.e. polystyrene ceiling tiles etc.

Overview
OVERVIEW
LBV00018; Revision E - 28/01/98

The projector is designed to be lifted using the finger grips on the base. Do not
attempt to lift the projector by holding the front or side covers.
Care should be taken when attaching the projector feet so that the projector does
not rest on its feet at an angle.
Never operate the projector with the cover removed, the arc lamp power supply
has a 30kV strike pulse mechanism, which is active during lamp switch-on.
NEVER look into the lamp housing, or attempt to remove the lamp from its
housing when the lamp is on.
Before attempting to remove any of the projector's covers, you must turn off the
projector and disconnect from the mains supply.
OTHER IMPORTANT SAFETY CONSIDERATIONS
In order to ensure that correct internal airflows are maintained, and that the
projector complies with Electro-Magnetic Compatibility requirements, it should
always be operated with all of it's covers in place.
Ensure that nothing can be spilled on, or dropped inside the projector. If this does
happen, switch off and unplug the mains supply immediately. Do not operate the
projector again until it has been checked by qualified service personnel.
The projector must always be mounted in a manner which ensures free flow of air
into its air inlets and unimpeded evacuation of the hot air exhausted from its
cooling system. The air exit duct at the top of the projector can become hot during
operation and should not be touched by the operator. Heat sensitive materials
should not be placed in the path of the exhausted air.
Do not move or tamper with any seals or ducting panels on the projector or the
air flow could be disrupted and cause the projector to overheat. Always keep the
air inlets and outlets clear of any obstruction.

projector.
6. With the screen or a wall illuminated, confirm the Menu System is operational
by pressing OSD ON then MENU on remote control (a main menu should be
clearly visible).
7. Turn the lamp off by depressing the LAMP OFF button on the remote control
for two seconds.
8. Power down the projector and disconnect from the mains supply.
9. Continue with the system installation.

Remote Receiver
The optional remote receiver acts as a relay between
the remote control and the projector and is useful for
installations where the Infra Red signal from the
remote cannot reach the sensors on the projector.
The Infra Red signals from the remote control are
picked up by the IR receiver on the front of the
remote receiver and are relayed to the projector via
the 15 way high density 'D' style connector on the
underside of the unit.
The remote receiver also allows direct cabling (hard
wiring) of the remote control unit via a 4 way
'LEMO' connector. When used in this way, the
remote control does not require batteries and the IR
receiver on the remote receiver is disabled.
Hard wiring has the advantage of allowing control
of the projector from a greater distance: The cable
from the remote control to the remote receiver can
be up to 10m (33ft) in length and the cable
connecting the remote receiver to the projector can
be up to 60m (200ft) long.
When hard wiring, the remote control unit must
be connected to the remote receiver before the
remote receiver is connected to the projector. If the
connections are not made in this order the remote
receiver fuse will trip and the remote receiver will
have to be disconnected for approximately one
minute before reconnecting in the correct manner.
For further information on remote receiver wiring,
see Cables and Connections, D—39.

LED Indicators
There are 3 Light Emitting Diodes (top - red, middle - green, bottom - red) at the
front of the case which indicate the status of the projector. The top red LED is used
to indicate that power is applied to the projector and that it is turned on. The middle
green LED indicates normal operation and flashes when the projector is receiving a
signal from the remote control unit. The bottom red LED indicates that the lamp has
failed. For further information see System Operation, C—6.
Arc Lamp
The projector uses a specialised, high pressure xenon arc lamp designed to operate
in conjunction with Digital Projection's optical condenser system and specialised
power supply unit. The lamp achieves maximum brightness immediately following
strike and is designed for an operating life of greater than 750 hours.
The operator is advised where possible to switch off the lamp using the 'LAMP
OFF' button on the remote control, and allow the cooling system to run on for two
minutes before switching off the mains supply.
The lamp is contained in a special safety housing to dissipate heat and to make
changing the lamp as easy as possible (see Fault Finding and Maintenance, E—6).
The customer should never attempt to disassemble the lamp from its housing or to
dispose of it other than by returning it to Digital Projection.
AÑ9
Overview
OVERVIEW
LBV00018; Revision E - 28/01/98
LEDs

Optics
The lamp faces downwards onto a 'cold mirror' which directs the light beam into a
condenser. A prism then splits the concentrated beam from the condenser into red,
green and blue light using dichroic filters and directs the light onto separate
DMDs™. The images produced by the three DMDs™ are then combined by the
prism to form a full colour image and directed into the lens for projection.
The condenser is precisely aligned in the factory. If it is moved there could be a
reduction in light output and image display quality.
Lenses
There are seven lenses available for the POWER display projectors which cater for
all foreseen user requirements. The lenses are identified by their ratio of 'Throw
Distance' to screen width, where 'Throw Distance' is the distance the projector must
be positioned from the screen to display an optimum image (see B—4, Positioning
the Projector).
At present, there are four fixed ratio lenses available for the projector (1.27:1, 3:1,
5:1 and 7:1), two zoom lenses; 1.5:1 to 3:1 and 3:1 to 7:1 respectively and an
SVGA Ultra Wide Angle lens.
1.27:1 is the accurate ratio for the lens marked as 1.2 and this ratio should be
used for any calculations.
The lens required will be dependant on the size of the screen, the 'Throw Distance'
available and the aspect ratios of the images to be displayed. If unsure which lens
would best suit your requirements, consult your dealer.
Only use lenses specified in this manual or recommended by Digital Projection.
