CAUTION ► Avoid smoky, humid and dusty places (e.g. near a humidifier, a smoking area, a kitchen etc.) Placing the projector in such a place could cause fire, electric shock and/or projector malfunction.

►Adjust the position of the projector so that light does not shine directly on the projector's remote sensor.

►The manufacturer strongly recommends avoiding any magnetic contact that is not shielded or protected on or near the projector itself. (e.g. Magnetic Security Devices, or other projector accessories that contain magnetic material that has not been provided by the manufacture etc.) Magnetic objects may cause interruption of the projector's internal mechanisms which may interfere with cooling fan speed or cause the fans to stop, and may cause the projector to shut down completely.
