Part 2: Repair Information 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. Lamp Age 0123 Hours Accumulated Illumination Time 2-19
