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.


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.

Precautions for servicing

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.
