Before operating the machine, please read the entire manual thoroughly. The 3M™ Multimedia Projector 8745
was 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
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 theappliance
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.

2.3System Setup - Connecting Various Equipment (continued)
Apple™ Desktop Mouse - The Macintosh operating system should recognize the MP8745 as a mouse
without any drivers being loaded.
ENGLISH
VirtualMouse for PC Computer - For IBM™ compatible computers, the operating systems will need to
be set to "Serial Mouse," "PS/2 Mouse," or "USB Mouse" to recognize the projector as a mouse pointer
device.
Change mouse driver information to "Serial Mouse," "PS/2 Mouse," or "USB Mouse."
"Mouse;" select the "General" tab; (see what driver is currently loaded and make note of it); select
"Change;" select "Show all devices;" (make note of the current Manufacturer and Model); select
"Standard Mouse Type" for Manufacturer; then select "Standard Serial Mouse," "Standard PS/2
Mouse," or "USB Mouse." Click OK to change and apply the new driver. Restart Windows if
prompted. USB mouse emulation is not supported in all versions of Windows 95.
b)Windows™ 3.1 - From "Program Manager" click "Main;" then click "Windows Setup," (make note of
what the current mouse driver is); Click "Options;" then "Change Systems Settings." Choose
"Mouse." It should be listed as "Microsoft or IBM PS/2." USB mouse emulation is not supported in
Windows 3.1.
✔Note
For proper mouse operation, always turn the projector power on first and then power up the computer.
For some laptop computers you may need to disable the internal pointing device (IPD). This is done through
the BIOS level set up of the particular machine, or it could be listed in a "Utilities" program group, i.e., "Toshiba
Utilities™," or "Thinkpad Features™."
