Safeguards  
INTENDED USE  
Before operating the machine, please read the entire manual thoroughly. The 3M™ Multimedia Projector 8770  
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  
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.  
Note - Used to emphasize important conditions or details.  
2.  
3.  
Close supervision is necessary when any appliance is used by or near children. Do not leave appliance unattended  
while in use.  
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.  
5.  
Care must be taken as burns can occur from touching hot parts.  
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.  
7.  
Position the cord so that it will not be tripped over, pulled, or contact hot surfaces.  
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.  
12.  
13.  
14.  
15.  
Connect this appliance to a grounded outlet.  
Do not expose this projector to direct sunlight, or use it outside.  
Keep all ventilation openings free of any obstructions.  
Always open the lens shutter or remove lens cap when the projection lamp is on.  
Do not look directly into light beam of laser pointer. The pointer produces a strong light which could damage your  
eyesight.  
16.  
17.  
The projection lamp contains mercury. Always dispose of it in a proper manner according to local regulations.  
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.

2.3 System Setup - Connecting Various Equipment (continued)  
Apple™ Desktop Mouse - The Macintosh operating system should recognize the MP8770 as a mouse  
without any drivers being loaded.  
VirtualMouse for PC Computer - For IBMcompatible 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."  
a) Windows95/Windows98 - 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," "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) Windows3.1 - 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."

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 with an 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.
