WARNING HOT! : Do not touch around the lamp cover and the exhaust vents during use or just after use, since it is too hot.

►Do not look into the lens or vents while the lamp is on, since the strong light is not good for your eyes.

►Do not handle the elevator buttons without holding the projector, since the projector may drop down.

CAUTION ►Maintain normal ventilation to prevent the projector from heating up. Do not cover, block or plug up the vents. Do not place anything that can stick or be sucked to the vents, around the intake vents. Clean the air filter periodically.

►Do not use the security bar and slot to prevent the projector from falling down, since it is not designed for it.
