INSTALLATION
Installation of the Projector and Screen
To set the screen size and projection distance, see the illustration and table below.
The projection distance shown in the table below
indicates the full size (1024 × 768 dots).
a:Distance from the projector to the screen (± 10%).
b:Distance from the lens center to the bottom of the
• Install the projector in a suitable environment as indicated in this manual.
• If you use a metal tool or the like to mount this unit, be sure to connect it via earth connection so
as to avoid a risk of fire or electric shock.
Connect the ground terminal of the AC inlet of this unit to the ground terminal provided in the
building using an optional three-core power supply cord.
• Always use the liquid crystal projector in a horizontal position, if possible. If you operate the
liquid crystal projector with its lens upwards, its lens downwards or to the side, the heat generated
inside the projector may build up and cause malfunctions or damages. Be especially careful to
never block the ventilation holes.
• Do not install the LCD projector in a smoky surrounding, since smoke residue may be
accumulating on critical parts (i.e. LCD panel, lens, etc.).
Side View
Angle Adjustment
Use the foot adjusters located on the bottom of the projector to adjust the angle of projection. This
angle can be adjusted within approximately 0° to 9°.
Foot Adjusters
Press the foot adjuster button
Rear Foot Adjuster
Lift up the front side of the projector and press the button of the foot adjuster to adjust the angle
1
of projection.
To lock the foot adjuster at the desired angle, release the button.
2
Turn the screw of the foot adjuster to precisely adjust it. Do not use force, since this could damage

Contact your dealer before replacing the lamp.
See the item “Optional Parts” in Table 12.
Before replacing the lamp, switch power OFF, remove the power cord from the power outlet, and
wait approximately 45 minutes until the lamp has cooled. The lamp may explode if handled at high
temperatures.
WARNING:
• For disposal of used lamp, treat according to the instruction of community authorities.
• Since the lamp is made of glass, do not apply shock to it and do not scratch it.
• Also, do not use old lamp. This could also cause explosion of the lamp.
• Premature lamp failure MAY be caused by an electronic component in the projector and not
necessarily the lamp. If unsure contact your local service center.
• If it is probable that the lamp has exploded (explosive sound is heard), disconnect the power plug
from the power outlet and ask your dealer to replace lamp.
• The lamp is covered by front glass, but, in rare cases, the reflector and the inside of the projector
may be damaged by scattered broken pieces of glass. Broken pieces could cause injury when
being handled.
• Do not use the projector with the lamp cover removed.
