Installation menu correctly to suit to the
Installation angle. Continuing to use the
wrong setting may affect component
reliability.

On Illumination
To obtain the best picture, the front of the
screen should not be exposed to direct
lighting or sunlight.
On Heat Dissipation
The temperature of the projector cabinet
may increase during or immediately after
use; however, this is not a malfunction.
On Screen
When using a screen with an uneven surface,
stripes pattern may rarely appear on the
screen depending on the distance between
the screen and the unit or the zooming
magnifications. This is not a malfunction of
the unit.
On Fan
Since the projector is equipped with a fan
inside to prevent internal temperature from
rising, there may be some noise. This is a
normal result of the manufacturing process
and does not indicate a malfunction. If,
however, in a case of abnormal noise,
consult with qualified Sony personnel.
About Lens Replacement
When the power is connected, do not attach
or remove the projection lens.
Do not attach any lens other than the
specified accessory lens sold separately.
