Voltage and Power Consumption

● Specifications are subject to change without notice.

● LCD panels are manufactured to the highest possible standards. Even though 99.99% of the pixels are effective, a tiny fraction of the pixels (0.01% or

less) may be ineffective by the characteristics of the LCD panels.

● Each projector has its own characteristics. When projecting with several projectors on the same screen or side by side, you may recognize different white balance and color uniformity on each projector.

● Interlock switch

The interlock switch (SW902) cuts off the AC mains power supply when the lamp cover is removed. 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 (SW905) inside of the projector to prevent the internal temperature from rising abnormally. When the internal temperature reaches near 90˚C, turn off the AC main power supply automatically. The thermal switch is not reset to normal automatically even if the internal temperature becomes normal. Reset the thermal switch following procedure. Check the resistance between terminals of thermal switch by using the tester. If it has high impedance, thermal switch may be in operative.

How to reset the thermal switch

1. Loosen 2 screws and open the lamp cover.

2. Press the reset button on the thermal switch with a sharp-

pointed tool.

CAUTION:

Before press the reset button, disconnect the AC cord from the projector.

Circuit Protections

This projector is equipped with the following circuit protections to operate in safety. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits.

● Fuse

Circuit Protections

● Warning temperature and power failure protection

The WARNING TEMP. indicator flashes red and the projector will automatically turn off when the internal temperature 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 WARNING TEMP. indicator still continues to flash, there may be defects on cooling fans or power supply circuits. 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 filters, follow the cleaning procedure below:

1. Tu rn the power off, and disconnect the AC power cord

from the AC outlet.

2. Tu rn the projector up side down and remove the air filters

by pulling the latches of them upward.

3. Clean the air filters with brush or wash out the dust and

particles.

4. Replace each air filter properly. Make sure that the air fil-

ters are 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”.

Service Adjustment Menu Operation

IC802 on the main board stores the data for the service adjustments, and should not be replaced except for the case of defective device. If replaced, it should be performed the re-adjustments following to the “Electrical Adjustments”. The data of lamp replacement monitor timer is stored in the IC802. Please note that the lamp replace counter is reset when the memory IC (IC802) is replaced. (Lamp replace counter can not be set to the previous value.)

● Caution of Main Board replacement (in the case IC802 is not defective)

When the main board is replaced, IC802 should be replaced with the one on previous main board. After replacement, it should be required to perform the readjustments following to the “Electrical Adjustments”.

In this case

, the lamp replace counter can be kept the

alue as before.

● Caution to memory IC replacement

When IC802 is replaced with new one, the CPU writes down the default data of the service adjustments to the replaced IC, refer to the service adjustment table. As these data are not the same data as factory shipped data, it should be required to perform the re-adjustments following to the “Electrical Adjustments”. Please note that the lamp replace counter is reset.

Before IC802 is replaced with new one, take a memo for the value of group/item no. "290 - 0" of the service adjustment data table, and after replacing IC802 change the value of group/item no. "290 - 1" to the same data with the memo.
