Important Operation Instructions

Warning

■ Before replacing the projector lens, be sure to read this

manual and the operation manual of the LCD projector for use with this lens.

To ensure safe operations and the continued safety of this product, be sure to follow all of the safety instructions written in this manual and the operation manual of the LCD projector.

■ Do not place the lens in a location subject to direct sunlight or other strong lighting or near heat-radiating equipment.

This can cause a fire due to the properties of the lens. It can also cause injury or damage to the lens.

■ Do not subject the lens to shocks.

This can cause injury or damage to the lens.

■ Be sure to unplug the LCD projector before replacing the lens.

The inside of the LCD projector has areas of high voltage which can cause electrical shock.

■ Do not touch the fan of the LCD projector during operation.

This can cause injury.

■ Before replacing the lens, be sure to turn off and

unplug the LCD projector, and allow at least 45 minutes for the projector to fully cool.

Before replacing the lens, be sure to turn off and unplug the LCD projector, and allow at least 45 minutes for the projector to fully cool.

■ When removing the louver, first shut off the projector and wait approximately ten minutes.

Removing while the cooling plate is still hot may result in burns.

■ When attaching, take care so that dust not enter inside.

Continued use with dust inside may result in fire or electric shock.

Caution

■ When replacing the lens, do not touch the LCD panels or polariz- ing plates of the LCD projector or subject them to shocks.

This can cause damage to the equipment. It can also cause a misalignment of the optical adjustment and, therefore, require readjustments.

■ When replacing the lens, be careful not to damage the connectors or wires inside the LCD projector.

This can cause damage to the equipment. Be careful not to pull on the connectors or wires or get them caught in the circuit board or case.

■ After replacing the lens, part of the lens and louver

(Only for models LENS-037 and LENS-038) may stick out from the LCD projector.

Transporting the LCD projector in the original projector shipping box can cause damage to the equipment.

Follow these Instructions

■Do not touch the lens directly with your hands or fingers. This can dirty the lens and cause deterioration in image quality.

■The lens is a precision optical device. Carefully handle the lens without subjecting it to shocks or vibrations.

■When resting the lens on a surface, place the lens face down on a soft cloth.
