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.

A lamp that has exceeded 2 000 hours of use has a much greater chance of exploding. In order to prevent the lamp from exploding, the lamp will be automatically shut off when 2 000 hours of use have been reached.

NOTE:

BThe usage hours explained above are for use when the HIGH setting has been selected for LAMP POWER in the OPTION menu. If the “LOW” setting is selected, the brightness of the lamp will be less and 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.
