How to check Lamp Used Time
The LAMP REPLACE indicator will light yellow when
the total lamp used time (Corresponding value) reaches
2,500 hours. This is to indicate that lamp replacement
is required.
The total lamp used time is calculated by using the be-
low expression,
Total lamp used time =
t
eco +
t
normal x 1.25
t
eco: used time in the Eco mode
t
normal : used time in the Normal mode.
You can check the lamp used time following to the be-
low procedure.

Should the air filter become clogged with dust particles, it will reduce the cooling fan’s effectiveness and may re-
sult 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”.
