If the temperature protector is activated
If the projector's internal temperature rises abnormally, the lamp turns off and the temperature indicator flashes (re-
peatedly in cycles of 2).
It may happen that the projector's temperature protector is simultaneously activated and the projector's power turns
off.
If this happens, do the following:
- Unplug the power cord from the power outlet.
- If using in a place where the surrounding temperature is high, move the projector to a different, cool place.
- If there is dust in the ventilation holes, clean. (→ pages
- Wait as such about 1 hour for the projector's internal temperature to lower.
