The LAMP REPLACEMENT indicator will illuminate
when the total lamp used time reaches 2000 hours.

Recommendation

it will reduce the cooling fan’s effectiveness and may
result in internal heat build up and short lamp life. We
recommend cleaning the air filter after the projection
lamp is replaced.
Refer to “Air Filter Cleaning”.
