Safety Instructions
Safety Precautions
WARNING:
The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side
of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is
identified with the line () in the schematic diagram. For continued product safety and protection of personnel injury, servicing should be made with qualified personnel.
The following precautions must be observed.
1: An isolation transformer should be connected in
the power line between the projector and the AC
line before any service is performed on the projector.
DO NOT OPERATE THIS PROJECTOR WITHOUT
THE PROTECTIVE SHIELD IN POSITION AND PR
OPERLY SECURED.
2: Comply with all caution and safety-related notes
provided on the cabinet back, cabinet bottom, inside
the cabinet or on the chassis.
3: When replacing a chassis in the cabinet, always
be certain that all the protective devices are
installed properly, such as, control knobs, adjustment covers or shields, barriers, etc.
4: Before replacing the cabinet cover, thoroughly
inspect the inside of the cabinet to see that no stray
parts or tools have been left inside.
Before returning any projector to the customer, the
service personnel must be sure it is completely safe
to operate without danger of electric shock.
Product Safety Notice
Product safety should be considered when a component replacement is made in any area of the projector.
Components indicated by mark ! in the parts list and the schematic diagram designate components in which
safety can be of special significance. It is, therefore, particularly recommended that the replacement of there
parts must be made by exactly the same parts.
Service Personnel Warning
Eye damage may result from directly viewing the light produced by the Lamp used in this equipment. Always
turn off Lamp before opening cover. The Ultraviolet radiation eye protection required during this servicing.
Never turn the power on without the lamp to avoid electric-shock or damage of the devices since the stabilizer
generates high voltages (15kV - 25kV) at its starts.

Maintenance
Cleaning
After long periods of use, dust and other particles will accumulate on the optical parts, mirror, color wheel, lens etc.,
causing the picture to darken or color to blur. If this occurs, remove dust and other particles using air spray. Before
taking the cleaning, turn off the projector and allow the projector to cool for more than 45 minutes. Never disassemble the optical unit, mirror or projection lens because those parts are aligned preciously in the factory . If do so,
the projector may have the miss-alignment in optical and reduce the optical performance.
Cleaning the Color Wheel
- The color wheel is made of thin glass. Be very careful
when handing the color wheel.
- In case of fingerprints, etc. on the surface, gently wipe
with a Cleaning Cloth for optical parts that contains a
small amount of non-abrasive camera lens cleaner to
clean the surface.
- Do not use detergents as this could cause peeling of
the color filter.
Cleaning the Projection Window
Unplug the AC power cord before cleaning.
First, remove the dust with a commercially available air blower. Then gently wipe the projection window surface. Use a
cleaning paper moistened with methyl alcohol (methanol).
Avoid using an excessive amount of cleaner.
Do not use abrasive cleaners, solvents, or other harsh
chemical cleaners to avoid damaging the projection window.
Cleaning the Reflecting Mirror
- Be careful not to touch the reflecting mirror. Touching
it directly with the hands may cause reducing the burnishing.
- Do not clean other than with air.
Caution:
The optical components may have a crack or spot when
you use the air spray directly to the optical components
while they are in the state of hot. Use a commercial (inert
gas) air spray designed for cleaning camera and computer equipment. Use a resin-based nozzle only. Be very
careful not to damage optical parts with the nozzle tip.
Cleaning the Projector Cabinet
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning cloth.
When the cabinet is heavily soiled, use a small amount of
mild detergent and finish with a soft dry cleaning cloth. Avoid
using an excessive amount of cleaner. Abrasive cleaners,
solvents, or other harsh chemicals might scratch the surface of the cabinet.
When the projector is not in use, put the projector in an appropriate carrying case to protect it from dust and scratches.
CAUTION
Do not use any flammable solvents or air sprays on the projector and in its vicinity. The explosion or fire hazard may
occur even after the AC power cord is unplugged because
the temperature inside the projector is extremely high due to
the lamps. In addition, there is a risk that the internal parts
may be damaged not only by the flammable air spray but
also by the cold air.
