[Recommendation]
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 short lamp life. We
recommend cleaning the air filter after the projection lamp is replaced.
Refer to “Air Filter Cleaning”.
[How to check lamp used time]
The LAMP REPLACE indicator will light yellow when the total lamp used time reaches
2,500 hours. This is to indicate that lamp replacement is required.
