•
The screen position may shift after installation if the projector is mounted on locations such
as the wall or ceiling, due to the flexibility of the plastic projector body. If readjustment is
necessary, consult with your dealer or service personnel.
•
The projected image position and/or focus may change during warm-up (approx. 30
minutes after the lamp is turned on) or when the ambient conditions change. Readjust
the image position and/or focus as necessary.
• Since the projector features an ultra short throw, be aware that it is required to select a
screen carefully to have better performance.
- A soft screen such as a pull-down screen may cause serious distortion of a projected image.
A hard screen such as a board screen is recommended for use with this projector.
- A high-gain screen such as a bead screen that has narrow viewing angle is not suitable
for this projector. A low-gain screen (around 1.0) such as a matte screen that has wide
viewing angle is recommended for use with this projector.
- A screen with a weave pattern may cause moiré on the projected image, which is not a failure
of the projector. A screen that has less moiré effects is recommended for use with this projector.
