Safeguards

INTENDED USE

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 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. 4. 5. 6. 7. 8. 9. 10. 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. 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. 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. Always unplug appliance from electrical outlet before cleaning and servicing and when not in use. Grasp plug and pull to disconnect. To reduce the risk of electric shock, do not immerse this appliance in water or other liquids. 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. 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. 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.

11. 12. 13. 14. 15. 16. 17. 18.
Always operate machine on a flat, sturdy surface.

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 MP8745 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 System Setup - Connecting Various Equipment (continued)
Apple Desktop Mouse - The Macintosh operating system should recognize the MP8745 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," "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) Windows 95/Windows 98 - 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) 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."

6.4 Replacing the Lamp

WARNING

To reduce the risk of electrical shock, always turn off projector and disconnect power cord before changing lamp.
To reduce the risk of severe burns, allow the projector to cool for at least 30 minutes before replacing the lamp. To reduce the risk of cuts to fingers and damage to internal components, use caution when removing lamp glass that has failed and shattered into sharp pieces.
Note For maximum lamp life, do not apply shock, handle or scratch the lamp glass when it is hot. Also, do not use an old or previously used lamp as a replacement lamp.
Remove lamp access door: The lamp access door is located on the bottom of the machine. Use a screwdriver to unscrew the cover retaining screw (1) and gently remove the cover (2) and set it aside. Retaining screws: Use a screwdriver to unscrew the lamp module retaining screws. (3)
Note All lamp module screws must be loosened. These screws are self-containing screws that cannot be removed from the lamp module or access door.
Remove lamp module: Carefully slide the lamp module out (4) using steady pressure.
To reduce the risk of cuts to fingers from sharp metal fittings and/or decreasing image quality by touching the lens, do not insert hand into the empty lamp compartment when the lamp has been removed.
Insert lamp module: Carefully insert (4) the new lamp module. Ensure that it is fully seated. Tighten the lamp module retaining screws (3) to secure the lamp module in place. Insert the hinge tabs on the bottom of the lamp access door, then close and tighten the retaining screw (1) to secure the door.
Note Reset the lamp operation hours. See section 6.3 for details.
