Lamp unit product no.: ET-LAP1 CAUTION: B Do 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 2 500 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 2 500 hours of use have been reached because of a much greater chance of it exploding after this time. NOTE: B While 2 500 hours is the intended replacement interval, it is not a period of time covered by warranty. ENGLISH-57 Care and maintenance
