Precautions
On safety
• Check that the operating voltage of your
unit is identical with the voltage of your 
local power supply.
• Should any liquid or solid object fall into
the cabinet, unplug the unit and have it 
checked by qualified 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 to 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. 
• Be careful not to get your fingers caught in
the adjuster.
• Do not spread a cloth or paper under the
unit.
On preventing internal heat build-
up 
After you turn off the power with the ?/1 
(On/standby) switch, do not disconnect the 
unit from the wall outlet while the cooling 
fan is still running.
Caution
The projector is equipped with ventilation 
holes (intake) and ventilation holes 
(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.
On repacking
Save the original shipping carton and 
packing material; they will come in handy if 
you ever have to ship your unit. For 
maximum protection, repack your unit as it 
was originally packed at the factory.
Cleaning the lens
The lens surface is especially treated to 
reduce reflection of light.
As incorrect maintenance may impair the 
performance of the projector, take care with 
respect to the following:
• Wipe the lens gently with a soft cloth such 
as a cleaning cloth or glass cleaning cloth.
• Stubborn stains may be removed with a
soft cloth such as a cleaning cloth or glass 
cleaning cloth lightly dampened with 
water.
• Never use solvent such as alcohol,
benzene or thinner, or acid, alkaline or 
abrasive detergent, or chemical cleaning 
cloth, as they will damage the lens surface.
Cleaning the cabinet
• To remove dust from the cabinet, wipe
gently with a soft cloth. If dust is 
persistent, wipe with a soft cloth slightly 
moistened with a diluted mild detergent 
solution.
• Never use any type of abrasive pad,
alkaline/acid cleaner, scouring powder, or 
volatile solvent, such as alcohol, benzene, 
thinner or insecticide. 
• Using such materials or maintaining
prolonged contact with rubber or vinyl 
materials may result in damage to the 
screen surface and cabinet material.
Black points and bright points (red, 
blue, or green) on the screen
The 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 projector.
This is a normal result of the manufacturing 
process and does not indicate a malfunction.
