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”.
How to check the accumulated illumination time
The LAMP REPLACEMENT indicator will illuminate when the accumulated
illumination time of the lamp reaches 1000 hours. This is to indicate that lamp
replacement is required.
You can check the accumulated illumination time of the lamp by following procedure.
1. Press and hold the pointer
on the projector for more than 20 seconds.
2. The accumulated illumination time is displayed on the right bottom corner of the
screen. For example, when “Lamp Age 123 hours” is displayed, the accumulated
illumination time of the lamp is 123 hours. This will disappear in 5 seconds.
