Safeguards
INTENDED USE
Before operating the machine, please read the entire manual thoroughly.  The 3M™ Multimedia Projector 8755/
8755L/8770/8770Lwas designed, built and tested for use indoors, using 3M™ brand lamps, 3M™ brand ceiling
mount hardware and nominal local voltages. This projector is not intended for household use. The use of other
replacement lamps, outdoor operation 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.
WARNING  - 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
moderate injury.  It may also be used to alert against unsafe practices.
    ✔Note - Used to emphasize important conditions or details.
2. Close supervision is necessary when any appliance is used by or near children.  Do not leave appliance unattended
while in use.
3. Never look directly into the projector lens when the lamp is on.  The high pressure mercury lamp produces a strong
light which could damage your eyesight.
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 any extension cord is necessary, a cord with 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, but take it to a qualified technician when
service or repair work is required.  Incorrect assembly can cause electric shock when the appliance is subsequently
used.
11. Connect this appliance to a grounded outlet.
12. Do not expose this projector to direct sunlight, or use it outside.
13. Keep all ventilation openings free of any obstructions.
14. Always open the lens shutter or remove lens cap when the projection lamp is on.
15. Do not look directly into light beam of laser pointer. The pointer produces a strong light which could damage your
eyesight.
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 
➮ ceiling mount or
ceiling 
➮ desktop mount) and continue to use the same lamp.
18. Always operate machine on a flat, sturdy surface.
