Lamp Replacement
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 = Teco + Tnormal x 1.25
Teco: used time in the Eco mode
Tnormal : used time in the Normal mode.
You can check the lamp used time following to the below
procedure.
1 Press and hold the ON/STAND-BY button on the pro-
jector or the remote control for more than 20 sec-
onds.
2 The projector used time and lamp used time will be
displayed on the screen briefly as follows.
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”.

Warning Message on the non-standard lamp used

Some of the functions are limited when the non-standard lamp is used in spite of the warning.
Since the lamp is not standard,
projector failed to read lamp data.
