What should I do if the projector lamp switches off after a period of time?

If the warning light indicator is red, the projector is overheating and automatically turns off. Leave the projector to cool for a few moments, then check that nothing is blocking the ventilation vents and clean the air filter if necessary. Turn on the projector again, and if the issue persists, contact your support provider at 1-800-968-9853. (Page 20)
