Lamp (Option Lamp:DT00531)
To replace the lamp, check the model number of the replacement lamp (sold separately).
Replacement lamp model number: DT00531
Before replacing the lamp, make sure the power switch is off and the power cable is not plugged in,
then wait at least 45 minutes for the lamp to cool sufficiently. Handling the lamp while hot can cause
burns, as well as damaging the lamp.
WARNING
bang, or burn out, if jolted or scratched, or through wear over time. Each lamp has a
different lifetime, and some may burst or burn out soon after you start using them. In
addition, when the bulb bursts, it is possible for shards of glass to fly into the lamp housing,
and for gas containing mercury to escape from the projector's vent holes.
• Do not open the lamp cover while the projector is suspended from above. This is
dangerous, since if the lamp's bulb has broken, the shards will fall out when the cover is
opened.
• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.
• If the replace lamp indicator (see "Related Messages" and "Regarding the
indicator Lamps" ) comes on, replace the lamp as soon as possible. Using the
lamp for long periods of time, or past the replacement date, could cause it to burst. Do
not use old (used) lamps; this is a cause of breakage.
• If the lamp breaks soon after the first time it is used, it is possible that there are electrical problems
elsewhere besides the lamp.
• If the lamp should break (it will make a loud bang when it does), ventilate the room well, and make
sure not to breathe the gas that comes out of the projector vents, or get it in your eyes or mouth.
• Obey local ordinances when disposing of used lamps. In most cases, it is possible to dispose of used
bulbs in the same manner as used glass bottles, but in some cases, bulbs are sorted separately.
• Do not use the projector with the lamp cover removed.
