Warning temperature and power failure protection
The TEMP WARNING indicator flashes red and the projector will automatically turn off when the internal tempera-
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.
When the above symptoms are noticed, please clean up the LCD panel and lens following to the “Cleaning
Method”.
