The LAMP REPLACE indicator will light 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 below expression;
Total lamp used time = Teco + Tnormal x (1.666)
Teco: used time in Eco mode
Tnormal: used time in Normal and Auto mode
You can check the lamp counter following procedure.
1 Press and hold the POWER ON-OFF button on the
projector or the remote control unit for more than 20
seconds.

displayed on the screen briefly.

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 clean-
ing the air filter after the projection
lamp is replaced.
Refer to “Air Filter Cleaning”.
