rProjection Lens
Be sure to use the standard zoom lens (for high brightness) supplied with the projector or the specified Projection Lens
(optional). The standard zoom lens supplied with PT-EZ570 series, PT-EW630 series, PT-EW530 series, PT-EX600 series,
PT-EX500 series is different from the lens of this projector. Using it may result in malfunction or damage. Do not use it.
The standard zoom lens supplied with the projector is for high brightness, and "Standard Lens for HighBrightness" is indicated
on the lens.
rFocus 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.
rDo 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.
rDo 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.
rCautions when setting up the projector
f When installing and using the projector with a method other than the floor standing installation using the adjustable feet, fix
the projector using the four holes (the upper left, the upper right, the lower left and one of two lower right 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.
f Use the adjustable feet only for the floor standing installation and for adjusting the angle. Using them for other purposes may
damage the projector.
f Do not stack projectors on top of each other.
f Do not use the projector supporting it by the top.
f Do not use the projector tilted at an angle that exceeds ±15° from the horizontal plane.
f Do not block the ventilation ports (intake and exhaust) of the projector.
