Lamp Replacement
The LAMP REPLACE indicator will light yellow when
the total lamp used time reaches 2000 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 =
T
eco +
T
normal x 2
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
below procedure.
1
Press and hold the POWER ON-OFF button on the
projector for more than 20 seconds.
2
The projector used time and lamp used time will be
displayed on the screen briefly as follows.
WARNING:
- For continued safety, replace with a lamp assembly of the same
type.
- Allow the projector to cool for at least 45 minutes before you open
the lamp cover. The inside of the projector can become very hot.
- Do not drop the lamp module or touch the glass bulb! The glass can
shatter and cause injury.

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”.
