Chapter 1 Preparation — Precautions for use
rFocus adjustment
The high clarity projection lens is thermally affected by the light from the light source, making the focus unstable in
the period just after switching on the power.
This projector is equipped with the active focus optimizer function that reduces shift in focus caused by the
temperature change of the projection lens or the change in brightness of the image. It is recommended to set the
[PROJECTOR SETUP] menu → [LENS] → [ACTIVE FOCUS OPTIMIZER] → [ACTIVE FOCUS] to [ON] when
using the projector.
When using the projector with the [ACTIVE FOCUS] set to [OFF], it is recommended to perform the focus
adjustment after 30 minutes or more have elapsed with the focus test pattern displayed.
For details of [ACTIVE FOCUS OPTIMIZER], refer to the [PROJECTOR SETUP] menu → [LENS] → [ACTIVE
FOCUS OPTIMIZER] (x page 128).
For details of the test pattern, refer to "[TEST PATTERN] menu" (x page 150).
rDo not install the projector at an altitude of 2 700 m (8 858') or higher above sea level.

(113 °F).
Using the projector in a location where the altitude is too high or the ambient temperature is too high may reduce
the life of the components or result in malfunctions.
