WARNING
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
moderate injury. It may also be used to alert against unsafe practices.
üNote - Used to emphasis 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 metal halide 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 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 ⇒ceiling
mount or ceiling mount ⇒desktop mount) and continue to use the same lamp.
18. To avoid deposits from forming on internal components, do not operate projector in extremely humid
environments (RH > 80%) or near any type of fine mist.
