8LED: DESCRIPTION AND
SWITCHING ON
Fig. 28
Some manufacturers offer screen-masking systems to
help frame the projected image and improve picture
contrast. This can be controlled by the second 12V output
on the projector
The screen-masking interface can be connected to output
, at the rear of the projector, or on the optional Remo-
te Input Interface.
- Rear projection: the screen must be translucent.
- Front projection: preferably, use a screen with black,
non-reflecting borders, which will perfectly frame the
projected image.
Avoid light shining directly on the screen during projection
as this will reduce contrast and black level detail on the
projected image. For the true cinema experience best
results are achieved with little or no ambient light.
Furniture and other objects with reflecting surfaces, as
well as light coloured walls should be avoided, as they
are likely to interfere with the screen’s characteristics.

Upon switch on (in position I) the projector will initialise,
indicated by the flashing red LED. Followed by stand-by
mode (red LED static) (
Fig. 31
).
We recommend the use of screens with low gain
specifications (i.e. 1.3 to 2). The use of high gain screens
should be avoided due to their limited viewing angle, which
is undesirable for a large audience.

Do not install - or operate - the projector on its
side: this position will dramatically shortens
the life of the lamp (Fig. 29).

8.1 SWITCH ON FROM STAND-BY
By remote control: press one of 1...9
By keyboard: press Arrow Up or Arrow Down.
Fig. 32
When switching on from stand-by, the projector will turn
on the lamp (flashing green LED); after a brief warm up
period the image will be displayed (green LED on). The
input automatically selected will be the last one memorised
prior to switch off
(Fig. 32)
.
9. DESCRIPTION OF CONNECTIONS
To obtain the best performance from your projector, we
recommend the use of good quality “video cables” to the
various signal sources (75 ohm Impedance).
Poor quality cables will cause inferior picture performance.
For optimum connectivity we recommend you follow these
simple steps:
- With exception of coaxial RCA/Phono type connectors,
always double-check that the plug is inserted the correct
way round to avoid damaging the plugs or the sockets
on the projector
(Fig. 33)
.

ENGLISH
8.2 SWITCHING OFF AND RETURNING TO STAND-BY
By remote control: press
By keyboard: press key
When switching off, the projector goes in to stand-by (red
and green LED flashing) memorising the input selection
at the time of switch-off.
The fans will continue to work until the lamp has cooled
down. They will stop automatically after this period.
8.3 FAILURE OF THE LAMP TO LIGHT
Switching on from stand-by. If the lamp fails to come on
(the projector will automatically make five attempts), an
error will be registered by a flashing red LED. This can be
reset by switching the power switch to position O.
You may experience difficulties switching on
the projector shortly after turning off into standby mode. This is not a fault. The lamp is still
too hot for the switch-on procedure to take
place.
Wait a few minutes before turning on again (position I),
this will allow the lamp to cool down to the correct temperature.
Fig. 33
- Remove cables by the plug and do not pull on the
cable itself.
- Avoid tangled cables.
- Position the cables carefully to avoid a trip hazard -
especially in low light areas
(Fig. 34)
.

The life of the lamp is dependant on the number
of times the projector is switched ON and OFF .

If the projector is at an angle in relation to the screen,
keystone distortion will occur. Use the keystone
adjustment to restore the projected image to the correct
shape. The angle of projection is limited to + or - 10
degrees. If the projector is level then use the lens shift feature
to correctly position the image on screen
(Fig. 47)

To obtain maximum quality of the projected image, we
recommend the installation of the projector on a level
platform parallel and central to the screen. In the event
that the picture is not correctly positioned use the lens
shift feature.
Should it not be possible to centralize the image by
adjusting the lens height, tilt the projector, but this will
create keystone error (please refer to 13.3.2).
