							This guide assumes the projector has been previously installed and configured in
accordance with the System Installation guidelines in this Manual. 
Setting Up the Projector
Check that the input source you wish to display is connected to the back of the 
projector. If it is not, and you are unsure how to connect the source, refer to System
Installation, B—13.
Connect the projector and the input device to the mains supply and switch on (the
projectors power button is located at the back, on the left hand side). After turning
the projector on, check that air is flowing out of the vent on the top of the projector
case, if it isnt, turn the projector off immediately and contact your dealer.
If after 25 seconds the projector lamp has not lit (and the red LED is illuminated on
the front of the projector), switch off the projector and turn it back on again.
When the projector starts up, it will display images using the settings defined by the
At Power Up section of the User Preferences - you may need to select new settings.
On Screen Display
The On Screen Display (OSD) displays the menu system and messages and unless
pre-set to OFF in the User Preferences, will appear when the projector starts up. 
The OSD must be turned ON if you wish to make changes to the projector set-up. If
it is OFF, it can be activated using the OSD ON button on the remote control.
When OSD is ON, the menu system can be temporarily removed by pressing
MENU on the remote control. To re-activate the menu system, press MENU again
and you will be returned to the last menu screen used.

							If there is no Image
Ensure the input source is sending a signal.
Check the input source is correctly connected, an LED will flash on the input board
at the rear of the projector if you have incorrectly connected the input device. Check
that a signal is being sent (e.g. if it is a video recorder, it is set to play).
Ensure the correct input and channel numbers have been selected.
Check the type of input source and the input number you have connected the device
to, then, select the appropriate settings in the Channel Set-up Function.
Ensure Pic Mute has not been inadvertently selected.
If Pic Mute is ON, press the Pic Mute button on the remote control to toggle it OFF.
Correcting Distorted Images
The image is out of focus.
Activate the On Screen Display then press the LENS button on the remote control
until the Focus dialogue box appears. Next, use the ñand òkeys to focus the
image (the ñkey will focus closer and the òkey will focus further away).
The image does not fit the screen.
Ensure the projector is placed in the correct position, then select the channel with
the required aspect ratio for the image you want to display. The aspect ratio can be
changed using the Modify option in the Channel Set-up function.
The image is stretched horizontally or vertically.
The image is being displayed with the wrong aspect ratio. Before changing the
aspect ratio, ensure you have selected the correct channel for your input device and
the horizontal and vertical sizes are correct.

							The On Screen Display (OSD)
A menu system is provided to access the projectors system and image input 
settings. In order to access the menu system OSD must be turned ON. If OSD is
ON but no menus are displayed press the MENU button on the remote control. The
MENU button temporarily removes or replaces the menu display allowing you to
exit the menu system and re-enter at the same point. To leave the menu system
completely, either press EXIT at the main menu or OSD OFF at any time. When the
menu system is re-entered, you will be at the Main Menu. Movement through the
menu system is controlled by the cursor and enter buttons on the remote control.
The Menu System
The MAIN MENUprovides access to the sub-menus which allow you to control
the projector and to view any system settings. A brief description of each sub-menu
is given below.
CHANNEL SET UP- allows you to create NEW channel configurations, SELECT
a channel and VIEW, COPY, MODIFY or DELETE that channel.
NEW
The NEW command allows you to set up a channel for a new input device.
Highlight a channel and select NEW, a new channel with the default parameters as
specified in the USER PREFERENCES menu will be automatically created. These
parameters can then be modified to meet your requirements.
SELECT
Channel selection can be made in two ways, by simply keying in the channel 
number on the remote control or by selection in the Channel Set Up screen. To
select a channel using the On Screen Display, highlight both the desired channel
and SELECT using the cursors then press ENTER.

							VIEW
The VIEW command will display information about the selected channel, the 
information cannot be modified in this function. To select a channel, highlight it
using the cursors and select VIEW.
COPY
The COPY command allows all or just selected parameters from a channel to be
copied to another channel. To copy a channel highlight both the desired channel and
COPY using the cursors then press ENTER. Next, enter the destination channel and
the parameters to be copied.
MODIFY
The MODIFY option allows you to change individual channel configurations. As
the Size & Position and Computer Mode parameters are defaults when you create a
new channel you can re-define them using this option.
DELETE
The DELETE command allows to to delete any unwanted channels (except the 
factory defaults). To delete a channel highlight it in the Channel Set Up screen and
select DELETE. For safety, you will be asked to confirm the deletion.
ADD COMPUTER - allows you to configure the projector to display different
computer card outputs. It also allows groups of computer modes to be created and
saved under a collective name. Other options include the modification, deletion and
copying of computer cards.
DELETE
It is possible to delete a single mode contained within a computer card or all modes
contained within a card (effectively deleting the complete card). Select the card
from the fly-out list in the Add Computer Screen, only computer cards you have
created are valid for deletion - factory supplied cards cannot be deleted. Assuming
you have selected a valid computer card, selecting DELETE will open the Delete
Computer window allowing you to select the appropriate modes.

							MODIFY/CREATE
If you selected an existing computer card it is possible to modify a specific mode
for that card. After selecting the mode to be modified from the resolution mode 
fly-out list you will enter the Mode Parameters window. The computer and mode
names will be displayed along with the previously defined parameters.
If you selected NEW, the Computer Name window will open asking you to enter
the name of the new computer. After entering the name and selecting OK, the mode
parameters window will appear to allow you to define its configuration.
COPY

with all its associated modes and give it a different name. It is not possible to copy
an individual mode, either within a computer card or between cards. To copy a
computer card, select it from the fly-out list and press COPY. After naming the new
version select OK to execute the copy.
IMAGE MODE- allows you to configure the projector for front or rear projection
and to define gamma correction for TV or Film inputs.
USER PREFERENCES- enable you to define the general defaults to be applied
when the projector is turned on.
TEST PATTERNS- are used to check the projectors alignment and performance.
SET ADDRESS- defines an individual projectors address when using multiple
projectors.

							Arc Lamp
The xenon arc lamp has a sapphire lens and a ceramic cover over the anode and
cathode. It operates at high temperatures and the beam contains high levels of ultra-
violet and infrared radiation. It is contained in a housing which acts as a heat sink.
Aspect Ratio
This is the ratio of picture width to picture height (the standard television aspect
ratio is 4x3).
Black body
An ideal body or surface that completely absorbs all light falling upon it with no
reflection.
Brightness
The light intensity of the displayed image.
Cold Mirror
This type of mirror filters infrared light, so that only cold light is reflected. In the
projector it is used to reflect the beam from the lamp into the condenser. 
Colour Temperature
The Colour Temperature is the position along the black body curve of the
chromaticity diagram - but takes into account the preset values for colour balance in
the service set-up to take up the variations in the prism.. The projector allows you to
adjust this temperature (i.e. adjust the picture colour) in steps of 100°K from 3000°
to 9900°.
Composite Signal
A signal line that carries information relating to the entire signal, also incorporating
sync pulses.
Contrast
The difference between the dark and light areas of the screen.

							DMD™
A Digital Micromirror Device™ is a true digital light modulator. See D—2,
DMD™ Usage and Operation for further explanation.
Field
A space on a menu screen for data to be entered.
Horizontal Scan Rate
This is the rate at which the horizontal lines of the incoming signal are refreshed.
The rate is set by the horizontal sync from the source and measured in Hertz.
Hs + Vs
This stands for Horizontal and Vertical sync.
Hue
The graduation (red/green balance) of colour (applicable to NTSC).
Hz - Hertz
Hertz is a measurement of frequency, where one hertz is one cycle per second.
Interlacing
An interlaced image is displayed by alternatively updating two fields of horizontal
display lines to produce a constant image. One field is updated, then the next field is
updated continuously.
LED
A Light Emitting Diode is an electronic component that emits light.
Lumen
The measurement of luminous flux.
Luminance
Also known as Y this is the part of an S-Video or component YUV signal which
affects the brightness, i.e. the black and white part.
