0 Projector Inputs
This menu lists the available inputs on the Remote Input
Interface (RI2). The interface is automatically recognisedby the projector during the power on sequence (red
flashing LED).
The Remote Control and the keyboard pad on the
projector can select the inputs available on the Remote
Input Interface. The 0 key allows switching between the
list of projector’s inputs and the list of Remote Input
Interface.
If a single signal is applied to the projector and
that source was selected, the image coming
from that input will be projected.
If signals are applied to several inputs, you can
select the desired input by one of the following
methods:
- browsing the Source Selection menu, by re-
mote control or rear key pad
- pressing the remote controls digit key
corresponding to the desired input
16 CLEANING AND MAINTENANCE
The projector does not require internal cleaning. There
are no user serviceable parts inside the projector.  Please
refer all service requirements to qualified personnel.
Cleaning the projector’s cover:
Use a soft slightly damp cloth. Do not use abrasive
cleaners, solvents or other harsh chemicals, as this will
damage the finish of the cover. Avoid direct cleaning of
the rear panel’s screen-printing 
(Fig. 48).
Fig. 48
Cleaning the lens:
The lens may be cleaned with a very soft, non-abrasive
small brush, in order to remove dust particles.
Alternatively, use a soft dry cleaning cloth (of the type
used for camera lens cleaning) to remove fingerprints and
grease marks.
The projector’s lens system is completely sealed; internal
cleaning is not needed.

 17 TROUBLESHOOTING GUIDE
Problems Solutions
No power:- Check the power switch at the rear: it must be in position I.
Green and red LED are OFF
- Check if the power cable has been connected correctly
to a working socket.
- Check the power socket fuse, at the rear of the projector.
- Replace the fuse on the mains socket with an identical
type  (T 3.15A H) 
(Fig. 8).
- Should the problem persist, seek authorised technical
assistance.
The lamp is not coming on:- Allow a few minutes pause between switching off and
turning on again (from stand-by). This will allow the lamp
to cool down sufficiently.
- If the lamp doesn’t come on – even though the projector
has had sufficient time to cool down – seek technical
assistance from your nearest Dealer.
No image:- Check that the selected input is actually connected to a
active video or graphic signal.
- Check that the above source actually works.
- Verify compatibility of video/graphic signals with the
technical specifications of the projector.
- Check the integrity of cables used to connect various
sources.
- If you are using the Remote Input Interface, do not to
confuse the menu for selection of projector’s inputs
(Source Selection), with the menu for selection of re-
mote inputs (Source Selection / RI2).
Image is disturbed, unstable or noisy:- Verify compatibility of video/graphic signals with the
technical specifications of the  projector.
- Check the integrity of cables connecting projector to
various sources.
- If the signal source is a terrestrial broadcast (via a VCR)
check that the receiving channel has been correctly tuned
in and that the aerial system is in good working order.
- Should the problem be present with a signal coming from
a video-recorder, ensure that the videotape is an Original
“first generation” copy and in good condition.
- Adjust the VCR’s tracking control for optimum picture
performance. Ensure the VCR mode is active in the
Picture  menu.

Incomplete image along borders (vertical and horizontal):- Compare compatibility of video/graphic signals and tech-
nical specifications of your projector.
- Press Auto (on your remote or key-pad) to execute
automatic adjustments.
- Adjust the horizontal and vertical position of projected
image by selecting  Position on the Image
Adjustments menu.
- Adjust the width and height of image, selecting Aspect
in the Image Adjustments menu.
Image too dark, too pale or unnaturally coloured:- Verify compatibility of video/graphic signals with technical
specifications of your projector.
- Go to Picture menu, select and regulate any of the following,
accordingly: Contrast, Brightness, Color, and Tint.
- If necessary, reset the Color Temperature and Gamma
Correction (found on the Image Adjustments menu /
Advanced Settings menu).
Graphic image with poor quality vertical detail:- Verify compatibility of video/graphic signals with technical
specifications of your projector.
- Press Auto (on your remote or key-pad) to execute au-
tomatic adjustments.
- Adjust Frequency and Phase  parameters, found in the
Image Adjustments menu, to optimise vertical detail
of the projected image.
Video Image showing colour misalignment on- Verify compatibility of video/graphic signals with technical
vertical details:specifications of your projector.
- Adjust Y/C Delay settings in the Image Adjustments /
Advanced Settings to reduce colour misalignment. For
best results use an external colour bar test pattern
source.
Remote control does not work:- Check the batteries and for correct polarity.
- Ensure that the area between the infrared sensor (front
of projector) and the remote control is free of obstruction.
- Ensure that infrared sensors (front and rear of projector)
are not exposed to intense light levels.

through the selected input
- Verify compatibility of video/graphic signals with
technical specifications of your projector.
- Check the integrity of cables used to connect various
sources.
- If you are using the Remote Input Interface, do not to
confuse the menu for selection of projector’s inputs
(Source Selection), with the menu for selection of re-
mote inputs (Source Selection / RI2).
High temperature:- Check temperature of the room: it must be below 35°C
(95°F)
The projector detects temperature internally; if it is
 too high it will switch itself off.
- Check projector air vents on top and underneath the
projector: they must be free of obstruction.
-  If the problem persists, consult your Dealer.
