INSTALLATIONS
1.2.1 Installation method The D-ILA system (reflecting type active matrix liquid crystal system) does not require convergence adjustment. Note the following when placed on a floor (refer to OPERATING INSTRUCTIONS for actual operating method). (1) Place the projector at the position needed for the required image size observe the projector is not tilted horizontally. [The image size is 40 to 200(wide side) inches diagonal (16:9), requiring a projection distance of 1.58m to 8.03m (wide side).] (2) Adjust the placement site and screen tilt so that the projection angle is perpendicular to the screen. (3) Adjust the placement site and screen position (height) so that the projection lens center is at the lower edge of the screen. (4) Project an image on the screen. (Connect video equipment and power source, switch power on and select the input.) (5) Fine adjust the projected image position and angle. If adjusting the placement site and screen cannot correct the projected position (too low) or angle (lower part of image widened), adjust the front foot. (6) Turn the lens ZOOM ring by hand and adjust for suitable image size. (7) Turn the lens FOCUS ring by hand and adjust to correct image blur. 1.2.2 Installation site and status The projector contains a fan for cooling. Obstruction of the ventilation openings can lead to internal overheating, abnormal operation and failure. Also observe there is plenty of free space between the projector and adjacent walls, ceiling and other equipment. Note that excess heat can cause failure and damage to both the projector and nearby equipment. Required spacing : Front = 15cm / left and right sides = 30cm / rear = 50cm (When the unit is enclosed with block according to the required spacing on the left side, provide the unit with adequate ventilation so that the temperature inside of the enclosed area is kept at the same temperature in the open space in the room.) Avoid locations that are wobbly or inclined. If the setting site floor has protrusions or horizontal cannot be maintained, there is risk the projector may drop, fall over, etc. If located in a site where left to right tilt is greater than ±5p and front to rear tilt greater than ±20p, particularly the optical system components can be severely affected and there is risk basic performance and quality of the projector cannot be maintained. Observe the site can stably bear the weight (approx. 6.2kg) of the projector over a long period of time. If mounted on a stand with casters, observe the casters are securely braked to prevent movement. Avoid suspending in a location subject to vibration. Both the projector and mounting fixture can be damaged. Do not place in the following types of locations. Especially, Avoid locations subject to dust, grit, smoke or other airborne contaminants. Use adequate caution when providing external ventilation, filters and dust protection. Near water or in humid sites Near heaters or heat generating equipment Dust or grit Direct sunlight Oily or tobacco smokes Very high or very low temperature

(2) Set [EVR-DC] to "90" for R, G, and B, respectively. (3) Set [DDIC] [R,G,B FLAT FIELD] to "0" and record the illumination intensity. (Non-driven illumination intensity.) (4) Set [DDIC] [G FLAT FIELD] to 1023. (5) Set the illumination intensity maximum by adjusting the EVR-DC_G voltage. Record the illumination intensity level that has been set. (Saturated illumination intensity.) (6) Set [G FLAT] to "0." Adjust DC_G to allow the illumination intensity to become a target value (*) for "0 IRE" (0 IRE.). (*) The target value for [0 IRE] must be set 1.05 times the non-driven illumination intensity value. (7) Set the [GAMMA] Control Point to "32." (8) Set [G FLAT FIELD] to "1023" and adjust "G Control point 32" to allow the illumination intensity level to become 0.95 times the saturated illumination intensity. The adjustment must be made in the rage between a non-driven point and a saturated point. (9) In the same manner, adjust "0 IRE" and "100 IRE2 for R and B, respectively. (10) Set [R,G,B FLAT FIELD] to "1023". Lower "RGB Control point 32" with least or no G reduction being introduced in order to obtain the chromaticity to "X - 0.3127 +/- 0.001 Y = 0.329 +/- 0.001 (The illumination intensity is set to "100IRE" that must be measured using the CL-200 Light-meter) INTERIM G GAMMA ADJUSTMENT (1) Set the Control Point of [GAMMA] to "32."
