Replacing the lamp unit

Warning

The lamp unit should only be replaced by a qualified technician.

When replacing the lamp, allow it to cool for at least one hour before handling it.

BThe lamp cover gets very hot, and touching it can cause burns.

Notes on replacing the lamp unit

BThe light generating lamp is made of glass, so dropping it or allowing it to hit hard objects may cause it to burst. Be careful when handling the lamp.

BDispose of the removed old lamp with the same care that would be taken with a fluorescent light.

BA Phillips screwdriver is necessary for removing the lamp unit.

NOTE:

BThe projector is not supplied with a replacement lamp unit. Please ask your dealer for details. Lamp unit product no.: ET-LAB10

CAUTION:

BDo not use any lamp unit other than the one with the product number indicated above.

Lamp unit replacement period

The lamp is a consumable product. Even when the full life of the bulb has not been exhausted, the brightness of the light will gradually decline. Therefore periodic replacement of the lamp is necessary.

The intended lamp replacement interval is 2 000 hours, but it is possible that the lamp may need to be replaced earlier due to variables such as a particular lamp’s characteristics, usage conditions and the installation environment. Early preparation for lamp replacement is encouraged.

The lamp will automatically shut off after approximately 10 minutes when 2 000 hours of use have been reached because of a much greater chance of it exploding after this time.

NOTE:

BThe usage hours explained above are for when “LAMP POWER” in the “OPTION” menu has been set to “HIGH” and when “AI” in the “PICTURE” menu has been set to “OFF”. If “LAMP POWER” is set to “LOW”, or “AI” is set to “ON”, the life of the lamp can be extended.

BWhile 2 000 hours is the intended replacement interval, it is not a period of time covered by warranty.
