Precautions

 

14

• Check that the operating voltage of your unit is 

identical with the voltage of your local power supply. 
If voltage adaptation is required, consult with 
qualified Sony personnel.

• Should any liquid or solid object fall into the cabinet, 

unplug the unit and have it checked by qualified Sony 
personnel before operating it further.

• Unplug the unit from the wall outlet if it is not to be 

used for several days.

• To disconnect the cord, pull it out by the plug. Never 

pull the cord itself.

• The wall outlet should be near the unit and easily 

accessible.

• The unit is not disconnected from the AC power 

source (mains) as long as it is connected to the wall 
outlet, even if the unit itself has been turned off.

• Do not look into the lens while the lamp is on.
• Do not place your hand or objects near the ventilation 

holes – the air coming out is hot.

• Avoid using an extension cord with a low voltage 

limited since it may cause the short-circuit and 
physical incidents.

• Do not catch your finger between the unit and surface 

of the floor when moving the projector installed on the 
floor.

• Be careful not to catch your finger in the cooling fan.
• Do not carry the projector with the cabinet on and with 

its cover open.

• Be sure to use two peoples to grasp both sides of the 

unit when carrying the unit.

• When the projector is mounted on the ceiling, the 

Sony PSS-630 Projector Suspension Support must be 
used for installation.

• Be sure to install the supplied dust cover when 

mounting the projector on the ceiling.

• Allow adequate air circulation to prevent internal heat 

build-up. Do not place the unit on surfaces (rugs, 
blankets, etc.) or near materials (curtains, draperies) 
that may block the ventilation holes.
Leave space of more than 30 cm (11 

7

/

8

 inches) 

between the wall and the projector. Be aware that 
room heat rises to the ceiling; check that the 
temperature near the installation location is not 
excessive.

• Install the projector on the floor or ceiling. Any other 

installation causes a malfunction such as color 
irregularity or shortening lamp life.

• Do not install the unit in a location near heat sources 

such as radiators or air ducts, or in a place subject to 

direct sunlight, excessive dust or humidity, 
mechanical vibration or shock.

• To avoid moisture condensation, do not install the unit 

in a location where the temperature may rise rapidly.

• Be sure to secure the cabinet cover firmly when 

installing to the ceiling firmly.

Warning
For customers who purchase this unit
If customers perform the installation described in this 
manual, an accident may occur, causing serious injury. 
Never install it by yourself. For installation, be sure to 
consult with qualified Sony personnel.
For dealers
Please read this Installation Manual thoroughly for safe 
installation.

• To obtain the best picture, the front of the screen 

should not be exposed to direct lighting or sunlight.

• Ceiling-mounted spot lighting is recommended. Use a 

cover over fluorescent lamps to avoid lowering the 
contrast ratio.

• Cover any windows that face the screen with opaque 

draperies.

• It is desirable to install the projector in a room where 

floor and walls are not of light-reflecting material. If 
the floor and walls are of reflecting material, it is 
recommended that the carpet and wall paper be 
changed to a dark color.

• After you turn off the power with the @ / 1 key on the 

control panel or on the Remote Commander, do not 
disconnect the unit from the wall outlet while the 
cooling fan is still running.

• Do not disconnect the AC power cord from the wall 

outlet while the fan is still running.

Caution
The projector is equipped with ventilation holes (intake 
and exhaust). Do not block or place anything near these 
holes, or internal heat build-up may occur, causing 
picture degradation or damage to the projector.

Before cleaning
Be sure to disconnect the AC power cord from the AC 
outlet.

On replacing the air filters
When the air filter replacement message appears, 
replace both air filters with new ones.
