Chapter 1 Preparation — Precautions for use

rrFocus adjustment

The 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. Before adjusting the lens focus, wait at least 30 minutes with the image projected.

rrDo not install the projector at elevations of 2 700 m (8 858') or higher above sea level.

Doing so may shorten the life of the components and result in malfunctions.

rrDo not use the projector tilted to the right or left.

Using the projector at a vertical angle that exceeds 15° may reduce product life or result in malfunction.

rrCautions when setting up the projector

ffWhen installing and using the projector with a method other than the floor standing installation using the adjustable feet, fix the projector using the four screw holes for ceiling mount (as shown in the figure).

(Screw diameter: M6, tapping depth inside the set: 12 mm (15/32"), torque: 4 ± 0.5 N·m)

Prevent a gap forming between the setting surface and the screw holes for ceiling mount on the projector bottom, for example, by inserting spacers (metallic) between them.

Adjustable feet

The positions of screw holes for ceiling mount and adjustable feet

ffUse the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other purposes may damage the projector.

ffDo not stack projectors on top of each other.

ffDo not use the projector supporting it by the top.

ffDo not use the projector tilted at an angle that exceeds ±15° from the horizontal plane. ffDo not block the ventilation ports (intake and exhaust) of the projector.
