INSTALLATIONS
1.4.1 INSTALLATION METHOD
This projector comes with the D-ILA system (reflecting type ac-
tive matrix liquid crystal system) that does not require conver-
gence 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, and observe that the projector is not tilted hor-
izontally. [Depending on the image size (60 to 200 inches
diagonal: wide side), the projection distance is approx. 1.8
to 12 m by warranty.]
(2) Adjust the placement site and screen tilt so that the projec-
tion angle is perpendicular to the screen. Adjust the place-
ment site and screen position (height) so that the projection
lens center is at the lower edge of the screen.
(3) Project an image on the screen. (Connect video equipment
and power source, switch power on and select the input.)
(4) Fine adjust the projected image position and angle. If ad-
justing the placement site and screen cannot correct the
projected position (too low) or angle (lower part of image
widened), adjust front feet.
(5) By using "ZOOM" in LENS CONTROL, adjust for suitable
image size.
(6) By using "FOCUS" in LENS CONTROL, adjust to correct
image blur.

1.4.2 INSTALLATION SITE AND STATUS
The projector contains some fans for cooling. If the air inlets or
the vent holes of cooling fans are blocked, cooling efficiency may
deteriorate and temperature inside this unit will rise, and then it
can lead to 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.
Therefore, please make sure pay attention not to block the air in-
lets or the vent holes of cooling fans and allow sufficient space
around this unit.
REQUIRED SPACING:
Top = 15 cm / left and right sides = 30 cm / rear = 20 cm (When
this unit is enclosed in a space with dimensions as indicated
above, ventilate accordingly so that the internal and external
temperatures are the same.)
• Avoid locations that are wobbly or tilted. 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 tilt is greater than ±30°, 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 of the projector
over a long period of time.
• If mounted on a stand with casters, observe the casters are se-
curely broken 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. For dust protection, use adequate cau-
tion when providing external ventilation, filters.
Near water or in humid sites
Dust or grit
Oily or tobacco smokes
Near heaters or heat generating equipment
Direct sunlight
Very high or very low temperature
• To attach the unit to the ceiling mount bracket, set the torque
between the range of 1.5N m to 2.0N m.
