• Avoid installing the unit in a location near
a heat or smoke sensor. Installing in such a
location may cause malfunction of the
sensor.
• Avoid installing the unit in a very dusty or
extremely smoky environment. Otherwise,
the air filter will become obstructed, and
this may cause a malfunction of the unit or
damage it.
• When using the unit at an altitude of 1,500
m or higher, set "High Altitude Mode" to
"On" in the Installation menu. Failing to
set this mode when using the unit at high
altitudes could have adverse effects, such
as reducing the reliability of certain
components.
• Set "Installation Attitude" on the
Installation menu correctly to suit to the
Installation angle. Continuing to use the
wrong setting may affect component
reliability.
On cleaning the lens and the
cabinet
• Be sure to disconnect the AC power cord
from the AC outlet before cleaning.
• If you rub on the unit with a stained cloth,
the cabinet may be scratched.
• If the unit is exposed to volatile materials
such as insecticide, or the unit is in contact
with a rubber or vinyl resin product for a
long period of time, the unit may
deteriorate or the coating may come off.
• Do not touch the lens with bare hands.
• On cleaning the lens surface:

solvent such as alcohol, benzene or

• On cleaning the cabinet:
Clean the cabinet gently with a soft cloth.
Stubborn stains may be removed with a
soft cloth lightly dampened with mild
detergent solution and wrung, followed by
wiping with a soft dry cloth. Never use

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.
