Safeguards

INTENDED USE

Before operating the machine, please read the entire manual thoroughly. The 3M Multimedia Projector MP8750 was designed, built, and tested for use indoors, using 3M lamps, 3M ceiling mount hardware and nominal local voltages. The use of other replacement lamps, outdoor operation, operation in environments containing heavy cigarette smoke or different voltages has not been tested and could damage the projector or peripheral equipment and/or create a potentially unsafe operating condition.

IMPORTANT SAFEGUARDS

1. Read and understand all instructions before using. Pay particular attention to areas where this symbol ! is shown.

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

Caution - Indicates a potentially hazardous situation which, if not avoided, could result in minor or

4. Care must be taken as burns can occur from touching hot parts.

5. Do not operate appliance with a damaged cord or if the appliance has been dropped or damaged - until it has been examined by a qualified service technician.

6. Position the cord so that it will not be tripped over, pulled or contact hot surfaces.

7. If an extension cord is necessary, a cord with an earth/ground and a current rating at least equal to that of the appliance should be used. Cords rated for less amperage than the appliance may overheat.

8. Always unplug appliance from electrical outlet before cleaning and servicing and when not in use. Grasp plug and pull to disconnect.

9. To reduce the risk of electric shock, do not immerse this appliance in water or other liquids.

10. To reduce the risk of electric shock, do not disassemble this appliance or attempt to service it yourself. Take it to a qualified technician when service or repair work is required. Incorrect reassembly can cause electric shock when the appliance is subsequently used.

11. The use of an accessory attachment not recommended by the manufacturer may cause a risk of fire, electric shock, or injury to persons.

12. Connect this appliance to a grounded outlet.

13. This unit is equipped with optical lenses and should not be exposed to direct sunlight.

14. Keep ventilation openings free of any obstructions.

15. Always operate machine on a flat, sturdy surface.

16. The projection lamp contains mercury. Always dispose of it in a proper manner according to local regulations.

17. To avoid premature lamp failure, do not change the mounting position of the projector (desktop mount or ceiling mount
