may cause malfunction.
Cleaning of the projector and the
ventilation slots
Use a soft cloth to clean the projector and the
ventilation grilles. When the grilles become dirty, wipe
them with a soft cloth dampened with diluted mild
detergent, and then wipe them with a dry cloth.
t
Clean the inside of the terminal cover frequently as
dust is apt to be collected.
To protect the surface of the projector from fading or
deteriorating:
t
Do not spray insecticide on or inside the projector.
t
Do not use benzine or thinner to clean it.
t
Do not let rubber or plastic materials contact with
projector.
Cleaning of the lens
Use a standard lens-cleaning brush or a piece of lens
tissue dampened with lens cleaning fluid. The lens
surface is fragile. Use only recommended, nonabrasive
lens-cleaning materials. Do not touch the lens with
your fingers.
Cleaning of the filter
Clean dust from the filter.
Before cleaning the filter, be sure to turn off the power
of the projector and unplug the power cord from the
outlet.
Clean the filter frequently (at least once a month).
Dust settling on the filter causes the temperature
inside the projector to increase abnormally, damaging
the internal parts and components and affecting the
panel’s lifetime, resulting in a breakdown.
t
When the temperature inside the projector is
abnormally high, the projector may automatically
turn off and go into the standby mode where the
light source lamp is off to protect the internal parts
and components.
1. Unplug the power cord.
