 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 projection window 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 projection window with bare
hands.
 On cleaning the projection window surface:
Wipe the projection window gently-with a soft
cloth, such as a glass cleaning cloth. Stubborn
stains may be removed with a soft cloth lightly
dampened with water. Never use solvent such as
alcohol, benzene or thinner, or acid, alkaline or
abrasive detergent, or a chemical cleaning cloth.
 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 solvent such as alcohol,
benzene or thinner, or acid, alkaline or abrasive
detergent, or a chemical cleaning cloth.
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.
On inspection of light source related parts
Since the unit uses a laser, when performing
maintenance or inspection of light source related
parts, particular attention and a safe environment
are necessary. Be sure to consult with qualified
Sony personnel.
On disposing used products
Do not dispose the used products and general
garbage together.
Correctly dispose of used products to avoid
harming the environment or the health of yourself
and others. Follow the disposal regulations of your
area.
On LCD Projector
The LCD projector is manufactured using high-
precision technology. You may, however, see tiny
black points and/or bright points (red, blue, or
green) that continuously appear on the LCD
projector. This is a normal result of the
manufacturing process and does not indicate a
malfunction.
