INTENDED USE
Before operating the machine, please read the entire manual thoroughly. The 3M™ Multimedia
Projector 8740 was designed, built and tested for use indoors, using 3M™ brand lamps and nominal
local voltages. 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.
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 – 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 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.

Caution
Turn power off to all devices before making connections. Never plug anything into the projector or
computer while any device is in operation.
The MP8730 must be powered down when making connections. The mouse emulation may not work if
the unit is not powered down before the mouse cable connections are made.
2.3.1 Apple™ Desktop Mouse - The Macintosh operating system should recognize the MP8740 as a mouse
without any drivers being loaded.
VirtualMouse for PC Computer - For IBM™ compatible computers, the operating systems will need to
be set to "Serial Mouse" or "PS/2 Mouse" to recognize the projector as a mouse pointer device
Change mouse driver information to "Serial Mouse" or "PS/2 Mouse."
a) Windows™ 95 - Click "Start"; select "Settings"; select "Control Panel". Click on "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" or "Standard PS/2 Mouse." Click OK
to change and apply the new driver. Restart Windows when prompted.
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".
✔ 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™."

A.7 Connection to the Control Signal Terminal
a)
Mouse emulation
(1) While the projector and computer are turned OFF, connect the projector and the mouse terminal of
computer using an appropriate cable. (PS/2, Serial or ADB)
(2) Turn ON the projector.
(3) Turn ON the computer.
(4) Select the correct mouse driver for the application. See computer's User Manual for this procedure.
✔ Note
In some Notebook computers which have internal pointing device, mouse emulation will not work unless the
internal pointing device is disabled. In this case, disable the internal pointing device in BIOS setting. Check
the computer's manual for procedure to follow to disable internal pointing device in BIOS setting.
Caution
Turn off the power to both the projector and computer before connecting. Connect the computer to the
control terminal of the projector using the appropriate cable.
