Page 22: The Air Filter
6-6 The Air filter The air filter should be cleaned about every 100 hours. If the indicators or a message prompts you to clean the air filter, clean the air filter as soon as possible. If the air filter becomes clogged by dust or the like, internal temperature rises and could cause malfunction.
Page 23: The Lamp
6-7 The Lamp WARNING The projector uses a high-pressure mercury glass lamp made of glass. The lamp can break with a loud bang, or burn out , if jolted or scratched, handled while hot, or worn over HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE time.Note that each lamp has a different lifetime, and some may burst or burn out soon after you start using them.
Page 24 6-8 Notice of AUTO adjustment Use of AUTO adjustment with the image through RGB input optimizes V_POSI, H_POSI, H_SIZE and H_PHASE automatically. In case that projected image has dark tone around its peripheral, AUTO operation sometimes makes artifacts in the image, shifts capture area and so on. Those failures are caused by period of image data is not exactly distinguished to period of blanking on signal processing.
