■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.

ture of the projector exceeds the normal temperature or when stopping cooling fans or when the internal power
supply lines are failed.
Check the following possible causes and wait until stopping the TEMP WARNING indicator flashing.
Possible causes
- Air filter is clogged with dust particles. Remove dust from the air filter 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)
If the TEMP WARNING indicator still continues to flash, there may be defects on cooling fans or power supply cir-
cuits. Please check fan operation and power supply lines referring to the “Power Supply Lines Chart”.
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 filter, 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 an air filter
by pulling the latches of them upward.
3. Clean the air filter with brush or wash out the dust and
particles.
4. Replace the air filter properly. Make sure that the air fil-
ter is fully inserted.
CAUTION:
Do not operate the projector with the air filter removed.The
dust is stuck on the LCD panel and the mirror, and it may
spoil the fine picture image.
Do not put the small parts into the air intake vents. It may
result in the malfunction of the projector.The air filter is
small parts.Take care that children don’t eat or swallow it.
RECOMMENDATION
We recommend to avoid dusty, smoky place for operating the projector. Using in dusty place may cause the picture
of poor 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.
