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.
    4Note - 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 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 Ð 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.
