■ Temp. Indicator and Cleaning
■ Warning Temp. Indicator
The WARNING TEMP. indicator flashes red when an internal temperature of the projector exceeds the normal temperature.
The indicator stops flashing when the temperature of the projector returns to normal.
When the WARNING TEMP. indicator continues to flash, check the items listed below.
1.
Ventilation slots of the projector may be blocked. In such an event,
reposition the projector so that the Ventilation slots cannot be
obstructed.
2.
The Air filter may be clogged with dust particles. Clean the Air filter
by following the section "Air Filter Care and Cleaning" below.
3.
If the WARNING TEMP. indicator remains on after performing the
above checks, the Cooling fans or the internal circuits may be mal-
functioning. Contact service personnel from an authorized dealer
or a service station.
■ Air Filter Care and Cleaning
The removable Air filter prevents dust from accumulating on the surface of the projection lens and projection mirror. Should
the Air filter become clogged with dust particles, it will reduce the cooling fans' effectiveness and may result in internal heat
build up and adversely affect the life of the projector. Clean the Air filter by following the steps below.
1.
Turn off the projector, and disconnect AC Power Cord from the AC
outlet.
2.
Turn over the projector and remove the Air filter by pulling the latch
upward.
3.
Clean the Air filter with a brush or wash out dust and particles.
4.
Replace the Air filter properly. Make sure that it is fully inserted.
CAUTION
Do not operate the projector with the Air filter removed.
Dust may accumulate on the LCD panels 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.
Operating Environment
We recommend avoiding dusty/smoky environments when operating a projector.
When using under dusty or smoky conditions, dust may accumulate on the lens, liquid crystal panels, or optical elements
inside the projector. This condition may degrade the quality of a projected image and the life of the projector.
When the above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.
■ Cleaning the Projection Lens
Follow these steps to clean the projection lens.
1.
Apply a non-abrasive camera lens cleaner to a soft, dry cleaning cloth. Avoid using an excessive amount of cleaner.
Abrasive cleaners, solvents or other harsh chemicals might scratch a surface.
2.
Lightly wipe the Projection lens with a cleaning cloth.
3.
When the projector is not in use, close the front cover.
