Safeguards
INTENDED USE
Before operating the machine, please read the entire manual thoroughly. The 3Mt Multimedia
Projector MP8660 was designed, built and tested for use indoors, using 3Mt 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

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 an 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 reassembly can cause electric
shock when the appliance is subsequently used.
11. The use of an accessory attachment not recommended by the manufacturer may cause a risk of
fire, electric shock, or injury to persons.
12. Connect this appliance to a grounded outlet.
!
13. This unit is equipped with optical lenses and should not be exposed to direct sunlight.
14. Keep ventilation openings free of any obstructions.
15. Always remove the lens cap when the projection lamp is on.
16. The projection lamp contains mercury. Always dispose of it in a proper manner according to
local regulations.

during cable hook up.
The power cord (Figure 3-3) is detachable from the
projector and has different connection plugs on each
end. Plug the female end into the power cord terminal
on the projector and the male end into a properly
grounded electrical outlet.

S-Video Connection
Some video devices can generate S-VHS video, or
S-Video (Y/C). The MP8660 will accept this signal
through the S-VIDEO1 or S-VIDEO2 connectors.
The S-VHS cable has identical round four-pin
connectors on either end (Figure 3-8). Connect one
end to the S-Video jack on the input source device,
and the other end to the S-VIDEO1 or S-VIDEO2
terminal on the MP8660. Remember to connect the
audio cables for sound output. S-video input signals
have priority over RCA jack input.

internal speakers are disabled.
Mouse Interface Cable Connection
The MP8660 remote control transmitter can be used to control the mouse button functions on your personal

3-2. Projector Set Up
Ambient Light
Whenever you have a choice, light the room from the rear, away from the projection screen. The MP8660 has
a brightness adjustment to achieve the best image possible.
Distance to Viewing Screen
The MP8660 can be used in a small or large meeting room to project a quality image from 51 cm (20 inches)
to 762 cm (300 inches) in size. The distance between the projector and the viewing screen and the zoom lense
setting (minimum to maximum) will determine the size of the projected image. Refer to the Technical
Appendix to determine how far away from the viewing screen you need to place the projector to fill the screen
with the projected image.
Remember that increasing the projector-to-screen distance also decreases the image’s brightness dramatically.
In other words, as the image grows larger, it also grows dimmer.
For best results, experiment to find the right combination of projector-to-screen distance and room lighting.
Carrying Handle
The MP8660 has a carrying handle that folds into the top of the projector housing. To raise the handle, push
up on the back end of the handle (Figure 3-14) and then lift upward.
ENGLISH
Figure 3-14. Unfolding Handle
Ceiling Mount Considerations
An optional ceiling mount bracket (Figure 3-15) is
required to install the MP8660 from the ceiling. For
this type of installation, the image must be vertically
and horizontally inverted.
See section 9-1 to order the ceiling mount kit.

Adjusting the Projector Elevation
The elevation can be adjusted by turning the foot adjuster (Figure 3-16) to raise or lower the angle of the
projector.
ENGLISH
Figure 3-16. Foot Adjusters
Note
Both adjusting feet must be raised or lowered the
same amount to project a level image on the
viewing screen. The elevation can be adjusted
from approximately 0.4 to 7.2 degrees.
Rear Projection
A semi-transparent screen (Figure 3-17) can be used to project an image and view it from the backside of the
viewing screen. For this type of installation, the image must be horizontally inverted.
