1. Cleaning the Projector
A). Cleaning the projector to remove dust and grime will help ensure trouble-free
operation.
1). Be sure to turn off and unplug the projector at least 30 minutes before cleaning.
Failure to do so could result in a severe burn.
2). Use only a dampened cloth when cleaning.
Do not allow water to enter the ventilation openings on the projector.
3). If a little water gets into the projector interior while cleaning,
leave unplugged in a well-ventilated room for several hours before using.
4). If a lot of water gets into the projector interior when cleaning, have the projector serviced.
B). Cleaning the Projection Lens
*When dust and fingerprints, etc. are on the lens surface, use
the designated glass cleaner (toraysee) to remove it as shown in the
figure at the right. For fingerprints and other soiling that are difficult
to remove with a dry cloth, use a designated glass cleaner (toraysee)
which has been moistened in water and then use a dry cloth
to dry it off. Or, apply a little optic lens cleaner to a clean soft cloth.
(Do not apply the cleaner directly to the lens.) Then, lightly wipe the lens
in a circular motion.

Caution:
*The projection lens surface has a special coating.
1. Do not use abrasive cleaners and detergents or solvents on the
surface.
2. To prevent discoloration or fading, avoid getting cleaner on the
projector case
C). Cleaning the Main Unit
1. Clean with a soft fuzz-free cloth. In case of severe soiling, use
a well-wrung cloth dipped in a neutral agent to remove soiling
and then finish with a dry cloth.
*Do not clean with thinner, benzene or similar agents as this
could lead to deterioration or peeling of paint.
2. In case of dust in suction or exhaust holes or the interior,
disassemble the main unit and use air to remove the dust from
the inside.
D). Cleaning the filters
In order to keep the interior of the projector clean, the projector is equipped with a filter to
keep out dust and other small particles. Normally, it is recommended that you change the
projector's filter around 500 hours of projector operation at least. If you are operating the
projector in a dusty environment, it is recommended that you clean the filter more often.
When used in fog machine environment, a filter change is recommended on a regular base.

-7-
The interval is depending on the smoke density.
Dust clogs at the filter will prevent the projector from drawing cool air to lower the internal
temperature. This could lead to overheating and cause the projector to malfunction or
become damaged.
Use a vacuum cleaner to clean the ventilation slots.
To clean the filter at the ventilation slots, refer to the following illustration:
Step1: Loosen the two screws on the cover of the ventilation slot.
Loosen the 2 screws

Step2: Remove the dirty filter; you can clean it directly using water. Leave it to dry
before replacing it for further use. If the filter is broken or greasy, please replace it by a
new one. (Filter Part nr: R9899704).
Take out the filter and clean it
Step3: Insert the clean filter.
Put the clean filter inside the cover

Step4: Reattach the filter cover and tighten the two screws.
Close the filter cover
Then, fasten the two screws

E). Lamp Replacement
The lifecycle of ordinary projection lamp typically lasts for 1500 hours before requiring
replacement (different lamp configurations will affect lamp life). From the OSD Menu, you can go
to LAMPS
ÆLamp1 or 2 Run Time to check how long a lamp has been used. You should also replace the
lamp when the projected image gets noticeably darker. Contact your local dealer to purchase new
certified lamps for your projector.
To replace the projector lamp
Step1: Turn off the projector and unplug the power cord. Let the projector cool for
approximately 15 minutes before removing the lamp module for replacement.
When you turn off the projector, the lamp inside the projector will still be very hot (approximately 200 ~ 300°C).
If you attempt to replace the lamp without allowing the projector to cool, you could risk scalding yourself. This
is why you should wait for no less than 15 minutes for the lamp to cool down in order to perform the
replacement safely.
Step2: Loosen the Lamp cover.
Loosen the 2 screws
