HIGH (corresponding to approx. 9300 degrees Kelvin), MEDIUM
(approx. 6500 degrees Kelvin), LOW (approx. 5000 degrees
Kelvin) and one PERSONAL setting controlled by the user with
separate adjustments for RED, GREEN and BLUE.
Generally, the HIGH value is more suitable for displaying graphic
images, MEDIUM and LOW for video images.
These adjustments are reserved for expert users since there is
a risk of obtaining results that impair projected image quality.
GAMMA CORRECTION
Determines the system’s response to the grey scale,
emphasising or attenuating the different grades of brightness
(blacks, dark, medium, light grey, whites) in the projected image.
The GRAPHICS setting is more suitable for computer images,
while the FILM and VIDEO settings are more suitable for video
images.
Y / C DELAY
In the case of Video and S-Video signals, it may be necessary
to correct horizontal colour misalignment within the projected
image. For a given video standard (e.g. PAL or NTSC) the stored
value does not normally require further fine-tuning, unless the
source or connection cable has changed.
MAGNIFICATION
Allows you to select the area to be viewed and then magnify the
projected image.
The degree of enlargement is selected in Zoom mode (identified
by a magnifying glass in the centre of the image) using the
and
keys. The area of the picture to be enlarged is selected
in Pan mode (symbol in the centre of the picture) using the
and
arrow keys.
You can toggle between Zoom and Pan mode by pressing the
key on the remote control.
SETUP
The setup menu contains less frequently used adjustments that
may be required during installation (e.g. On Screen Display
language selection or the display of Test Patterns).
LANGUAGE
Lists the languages available for the On Screen Display menus.
OSD POSITION
Allows the On Screen Display to be positioned in a particular
area of the projected image. The OSD can be positioned using
the arrow keys for fine adjustments or keys 1...9 on the remote
control to select one of 9 preset positions.

OSD BACKGROUND
Determines the type of background for the On Screen Display.
OSD TIMEOUT
Use this adjustment to set the display time after which the On
Screen Display will disappear.
TEST PATTERNS
Displays a series of test patterns that are useful when
installing the system and checking basic functions. Use the
and
keys to browse through the test patterns.
FACTORY DEFAULTS
Restores original factory settings except for POSITION and
Y/C Delay.
INFO
Displays the current status of the projector and information
concerning the projected video/graphic signal.
This function is displayed on pressing on the remote control
(or, in the absence of the On Screen Display, the
key on the
remote control).
QUICK MENUS
The quick menus provide access to the main adjustments that
affect image quality, without calling the main On Screen menus.
BRIGHTNESS, CONTRAST, COLOUR, TINT, SHARPNESS
and FILTER adjustments appear at the bottom of the screen
one after the other when the
and keys are pressed
.
MESSAGES
The following messages may appear during operation of the
system:
No Signal
The system does not recognise any signal applied to the selected
input. In this case:
•
Make sure the selected input is connected to a video or
graphic signal and that that source is functioning correctly.
•
Check the condition of the cables used to connect the system
to the various sources.
•
Make sure the video or graphic signals supplied by the source
are compatible with the system’s technical specifications and,
in particular, with those of the selected input.
Out of Range
This message appears when either the resolution or the vertical/
horizontal frequency of the input signal exceeds system
specifications (e.g. a QXGA graphic signal) or when an input is
supplied with an incompatible signal (after setting the
components input to YCrCb 15kHz a progressive signal is
connected).
