■Safety Instructions
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 iden-
tified 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.
SAFETY PRECAUTIONS
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.
2: Comply with all caution and safety-related notes pro-
vided 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.
DO NOT OPERATE THIS PROJECTOR WITHOUT
THE PROTECTIVE SHIELD IN POSITION AND
PROPERLY SECURED.
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.
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.
Since the lamp is very high temperature during units operation replacement of the lamp should be done at least
45 minutes after the power has been turned off, to allow the lamp cool-off.
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.
DO NOT ATTEMPT TO SERVICING THE REMOTE CONTROL UNIT.
Laser Beam may be leaked out when in disassemble the Unit. As the Laser Beam used
in this Remote control unit is harmful to the eyes.

●Lamp cover switch
The lamp cover switch (SW901) cuts off the drive signal to the
lamp circuit when the lamp cover is removed or not closed com-
pletely. After opening the lamp cover for replacing the lamp ass’y,
place the lamp cover correctly otherwise the projector can not
turn on.
●Thermal switch
There is the thermal switch (SW902) inside of the projector to
detect the internal temperature rising abnormally. When the inter-
nal temperature reaches near 90˚C, it cuts off the AC main power
supply .
The thermal switch cannot be reset itself automatically even if the
internal temperature becomes normal. Reset the thermal switch
following to the below procedure.
How to reset the thermal switch
1. Insert the sharp tool like a screwdriver into a hole on the cabi-
net bottom.
2. Press the reset button on the thermal switch with the screw-
driver.

Before press the reset button, make sure that the AC cord must
be disconnected from the AC outlet.
This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the pro-
jector, it will automatically turn off by operating one of the following protection circuits.
●Fuse
A fuse is located inside of the projector. When the POWER indica-
tor is not lightning, the fuse may be opened. Check the fuse as fol-
lowing steps.

Circuit Protections
●Warning temperature and power failure protection
The projector will be automatically turned off when the internal temperature of the projector is abnormally high, or
the cooling fans stop spinning, or the power supplies in the projector are failed.
- If the WARNING indicator is flashing, it may detect the abnormal temperature inside the projector. Check the fol-
lowing possible causes and wait until the WARNING indicator stops flashing, and then try to turn on the projector.
- If the WARNING indicator lights red, it may defect the cooling fans or power supply circuits. Check fans operation
and power supply lines referring to the chapter “Power supply & protection circuit” in the Chassis Block Diagram
section.
Possible causes
- Air filters are clogged with dust particles. Remove dust from the air filters by following instructions in the “Air filter
care and cleaning” below.
- Ventilation slots of the projector are blocked. In such an event, reposition the projector so that ventilation slots are
not obstructed.
- Check if projector is used at higher temperature place (Normal operating temperature is 5 to 35 ˚C or 41 to 95˚F)
Air filter care and cleaning
The removable air filter prevents dust from accumulation on the surface of the projection lens and projection mirror.
Should the air filter become clogged with dust particles, it will reduce the cooling fan’s effectiveness and may result
in internal heat build up and reduce the life of the projector.
To clean up the air filters, follow the cleaning procedure
below:
1. Turn the power off, and disconnect the AC power cord
from the AC outlet.
2. Turn the projector up side down and remove air filters
by pulling the latches of it upward.
3. Clean the air filters with brush or wash out the dust and
particles.
4. Replace the air filters properly. Make sure that the air fil-
ters are fully inserted.
CAUTION:
Do not operate the projector with the air filters removed.
Dust may accumulate on the LCD panel and the projection
mirror degrading picture quality.
Do not put small parts into the air intake vents. It may result
in malfunction of the projector.
RECOMMENDATION
We recommend not to use the projector in dusty, smoky places. Using it in dusty place may cause the poor picture
quality.
When using under the dusty or smoky conditions, dust may accumulate on the LCD panel and lens inside it, and
may resultantly be projected on the screen together with the picture.
When the above symptoms are noticed, please clean up the LCD panel and lens following to the “Cleaning
Method”.
