2. INSTALLATION
This section describes how to set up your GT950 projector and how to
connect video and audio sources.
Setting up Your Projector
Your GT950 Projector is simple to set up and use. But before you get
started, you must first:
1. Determine the image size.
2. Set up a screen or select a non-glossy white wall onto which you
can project your image.
3. Connect the supplied power cable.
4. Set up the projector.
5. Connect a PC, VCR, DVD player, or other equipment.
6. Make setting or adjustments on the projector.
Selecting a Location
The further your projector is from the screen or wall, the larger the
image. The minimum size the image can be is approximately 25" (0.64
m) measured diagonally when the projector is roughly 3.9 feet (1.2 m)
from the wall or screen. The largest the image can be is 300" (7.6 m)
when the projector is about 39.4 feet (12.0 m) from the wall or screen.

WARNING
•Installing your projector on the ceiling must be done by a quali-
fied technician. Contact your NEC dealer for more information.
* Do not attempt to install the projector yourself.
•Only use your projector on a solid, level surface. If the projector
falls to the ground, you can be injured and the projector se-
verely damaged.
•Do not use the projector where temperatures vary greatly. The
projector must be used at temperatures between 32˚F (0˚C)
and 95˚F (35˚C).
•Do not expose the projector to moisture, dust, or smoke. This
will harm the screen image.
•Ensure that you have adequate ventilation around your projec-
tor so heat can dissipate. Do not cover the vents on the side or
the front of the projector.If your projector is mounted on the ceiling and your image is upside
down, use the “Menu” and “Select” buttons on your projector cabinet or

 button on your remote control to correct the orientation. (See page
E-43.)
Reflecting the Image
Using a mirror to reflect your projector’s image enables you to enjoy a
much larger image. Contact your NEC dealer if you need a mirror. If
you’re using a mirror and your image is inverted, use the “Menu” and
“Select” buttons on your projector cabinet or 
 buttons on your re-
mote control to correct the orientation. (See page E-43.)

mulas below.
