CAUTION
• Install the projector in a suitable environment as indicated in this manual.
• If you use a metallic hardware support to mount this unit, be sure to ground it to avoid a risk of
fire or electrical 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 projector in a horizontal position. If you operate the 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 damage. Never block the ventilation holes.
• Do not install the projector in a smoky environment, since smoke residue may accumulate on
critical parts (i.e. LCD panel, lens, etc.).

Angle Adjustment

Use the foot adjusters located on the bottom of the projector to adjust the projection angle. This
angle can be adjusted within approximately 0° to 9°.
Foot Adjuster
• Lift up the front side of the projector, then press the button of the foot adjuster to adjust the angle
of projection.
• To lock the foot adjuster at the desired angle, release the button.
• Rotate the screw of the foot adjuster to precisely adjust it. Do not use force, since this could dam-
age the adjuster or result in a failure of the lock.
CAUTION
• Do not release the foot adjuster button unless you are holding the projector securely.
