4. COMMENTARY4.1 Optical System
High brightness and high contrast are implemented at a low cost
by a newly designed1.4 wide zoom lens and an improved LCD panel,
combined with the Canon's unique 3Pprisms.
l 1.4 wide zoom lensA wide zoom lens with a short focal length
of 20.3 mm and high magnification of 1.4is designed as a bright
large-aperture projection lens (F1.6).The optical system has 10
groups of 10 lenses, including 5 groups of zoom lenses.The number
of lenses has been reduced and the zoom lenses have been
designedoptimally using a replica aspherical lens for G1 and
double-sided aspherical lens forG9 to suppress distortion
aberrations due to widened angles.All lenses are made from
lead-free glass.
l LCD panelThe new type of LCD panel has a higher open area
ratio than conventional ones byimproving production technologies to
increase efficiency of using light.
* Since the wide projection lenses are used, the F value
increases, but the lightintensity is the level of the previous
model.
l 3P prismLike the clear prisms for X1/S1, the 3P prism produces
images with uniform color onthe screen.The cost has been cut down
by reducing the number of parts.
l Projection screen sizeA29 to 200" screen display at the proper
projection distance of 1.1 to 8.0 m(See 6.1 Relationship between
screen distance and screen size.)
4.2 Functions
l Zoom/focusThe Wide/Tele zoom ratio is 1.4, and the projection
size can be changed by manualzooming within the range.The focus can
be adjusted to the correct point manually.
l Monochrome expansionIt is effective when projecting dark
images at night scenes or blurred images with alow contrast.When
this function is turned on, the video signal output is controlled
automatically tomaximize the black and white levels of output
images.
-
Part 1: General Information
1-8
l Flesh color correctionThe image is processed so that the color
of the skin of persons on the screen is real.When this function is
turned on, gradations are changed to the flesh color is set to
thepreset value.Since gradations are changed, the background color
may become different.
4.3 DesignThe high-quality and all-round "Stylish Form" fits
various office environments and
presentation scenes.The wide zoom lens with a short focal length
makes it possible to install the projector
in various places, from bright offices and home theaters for
watching movies.
l StylingThe comfortable and elastic three-dimensional form is
combined with a design like avideo equipment to produce a shape
that makes the user proud of owning it and givean impression of
precision and high quality.The impressive and stylish design,
measures to assure high intensity and high imagequality, and the
compact layout are balanced at a high level.
l DetailsThe operation panel is designed to be round with a
curved relief and have Caribbeanwater blue color. The "circle"
symbolizes "harmony, link, bond and communication",and "water"
symbolizes "light, life, purity and transparency". It evokes a
sophisticatedimage, high quality and is user-friendly so that it
can be used in various places.The operation panel on top of the
projector is inclined backward to improveoperability. Operation
keys are laid out around the cursor keys so that they can
beoperated by touching without looking at them.The exhaust port
that exhausts heat and causes noise has been laid out at the
frontpanel far away from audience, and is covered with a punching
metal to improve theappearance of the front panel and give an
impression of sophisticated image.
l Long life designA material with a color that is not faded
easily by stain or discoloration has beenselected. It is designed
to be in harmony with the atmosphere of many installationlocations,
and gives a feeling of high quality so that it can be used for a
long period oftime.
l Remote controlA thin card type of remote control is used like
the one used with the LV-X1/S1. Theremote control is designed not
only to look good, but also be user friendly, and can beused
easily.

1. SAFETY INSTRUCTIONSThe following precautions must be observed
during servicing and inspection.
Observe all safety precautions.Comply with all caution and
safety-related notes provided on the cabinet back, cabinet
bottom, inside the cabinet, on the chassis or components, as
well as the precautionsshown in the instruction manual during
servicing.
Avoid electric shock.Since an AC voltage is applied to the
chassis for the set, touching the chassis during
power-on may cause electric shock. When service is performed
during power on, use aninsulation transformer, wear protective
gloves, and remove the plug during partsreplacement. As there are
high-voltage areas inside the projector, handle it with carewhen
the power is on.
Use specified parts.The parts of the set have safety properties,
such as inflammability and voltage
withstand. Therefore, use replacement parts with the same
characteristics as theoriginal ones. The critical components for
safety are indicated by mark in theschematic diagram and parts list
must be replaced by the recommended parts.
Reinstall parts and wires in their original positions.Insulating
materials, such as tubes and tape, are used and some components
are
installed over a PC board for safety. Reinstall internal wires
with clamps so that they donot touch any heat-generating or
high-voltage parts.
Safety check after serviceVerify that service locations are not
deteriorated and all removed screws, parts and
wires are installed in their original positions. In addition,
perform the following test toensure safety.Insulation resistance
test method
Remove the plug from the electric outlet and press the power
switch. Using a 500Vinsulation resistance tester (or a multimeter
if any insulation resistance tester is notavailable), check that
the insulation resistance between each terminal of the plug
andexternal exposed connector (external speaker connector, remote
control connector, AVinput/output connector, etc.) is 1M ohm or
higher. If not, the set must be inspectedand repaired.
Components indicated by mark designate components in which
safety can be of special significance.It is, therefore,
particularly recommended that the replacement of these parts be
made by exactly thesame parts. Using unspecified parts may worsen
failure or cause fire or electric shock.
Eye damage may result from directly viewing the light produced
by the lamp used in this equipment.Always turn off the lamp before
opening the cover. Never turn the power on without the lamp to
avoid electric shock or damage of the devices since thestabilizer
generates high voltages (15kV - 25kV) at its starts.Since the lamp
is very high temperature during units operation replacement of the
lamp should be doneat least 45 minutes after the power has been
turned off, to allow the lamp cool-off.

CAUTIONFuse of the specified parts number must be
used.Unauthorized substitutions may result in fire or accident.
Components indicated by a mark in this schematic diagram
designatecomponents in which safety can be of special significance.
It is, therefore, particularly recommended that the replacement of
these parts must be made by exactly the same parts.
This projector is isolated from AC line by using the internal
converter transformer.Please pay attention to the following notes
in servicing.1 Do not touch the part on hot side (primary circuit)
or both parts on hot and cold sides (secondary circuit) at the same
time.2 Do not shorten the circuit between hot and cold sides.3 The
grounding lead must be connected to the ground of the same circuit
when measuring of voltages and waveforms.
