Cleaning and the 
Screen of the 
Projector
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.
