Lamp Replacement
The LAMP REPLACEMENT indicator will illuminate
when the total lamp used time reaches 2000 hours.
The total lamp used time is calculated by using the
below expression,
Total lamp used time =
T
eco +
T
normal (1+1/3)
T
eco : used time in the Eco mode
T

This is to indicate that lamp replacement is required.

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”.
