Reference for Installation

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  accumulat on crit-

ical parts (i.e. LCD panel, lens, etc.).

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°.

• 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.
