WARNING
Caution
Caution
Intended Use
Before operating the machine, please read this entire manual thoroughly. The 3M™Multimedia Projector MP7640/
MP7740 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 these symbols are shown:
Indicates a potentially hazardous situation which,
if not avoided, could result in death or serious injury.
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 mercury lamp produces a strong light that
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 placed in contact with hot surfaces.
7. If an 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. 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. 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 the lens cap when the projector 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 prevent lamp from bursting, do not continue using the same lamp after changing the mounting position of the
projector (desktop to ceiling mount or ceiling mount to desktop mount).
18. Always operate machine on a flat, sturdy surface.
