(trapezoidal distortion correction) is overly adjusted.
• Keystone correction (trapezoidal distortion correction) may be
limited with some lenses.
Important Operation Instructions
Warning
■ 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.
■ 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.
■ 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 down.
■ When attaching, take care so that dust does
not enter inside or stick to the connector.
Continued use with dust inside may result in fire or
electric shock.
■ If the projector is mounted on a ceiling, ask the
dealer to replace the lens.
This can cause injury.
Caution
■ When replacing the lens, do not touch the LCD
panels or polarizing 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.
