Avoid installing the unit in a location subject to 
direct cool or warm air from an air-conditioner. 
Installing in such a location may cause 
malfunction of the unit due to moisture 
condensation or rise in temperature.
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 in a location at an altitude 
of 1,000 m (approx. 3,280 feet) or higher, 
appropriately set “High Altitude Mode” in the 
“Installation” menu. Failing to do so could have 
adverse effects, such as reducing the reliability 
of certain components.
Avoid installing the product in a space where 
space disinfectant components containing 
hypochlorous acid and chlorine dioxide are 
dispersed. Also, avoid spraying sanitizers or 
disinfectants near the product. This may cause 
discoloration of the product, deterioration of the 
material, failure due to corrosion, and easy 
clogging of the air filter.
Be sure to disconnect the AC power cord from 
the wall 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:
Wipe the lens 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. Do not use alcohol, benzine, 
thinner, sanitizers, or disinfectants.
To obtain the best picture, the front of the screen 
should not be exposed to direct lighting or 
sunlight.
The temperature of the projector cabinet may 
increase during or immediately after use; 
however, this is not a malfunction.
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.
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.
