This section describes how to set up your VT650 projector and
how to connect video and audio sources.
Setting up Your Projector
Your VT650 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.
Carrying the Projector: Always carry your projector by
the handle. Ensure that the power cable and any other cables
connecting to video sources are disconnected before moving the
projector.
When moving the projector or when it is not in use, cover the
lens with the lens cap.

Adjusting the Tilt Foot
1) Press and hold the Tilt button on the front of the pro-
jector.
2) Lift the front edge of the projector to the height you
want, and release the button to lock the Adjustable
Tilt Foot.
To fine-tune the image’s position vertically on the screen,
rotate the foot. Each of the rear feet height can be
changed up to 0.6” (4mm). Carrying handle
2. INSTALLATION
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
3.5 feet (1.1 m) from the wall or screen. The largest the image
can be is 300 (7.6 m) when the projector is about 36.6 feet (11.2
m) from the wall or screen.
Using a Tabletop or Cart
1. Place your projector on a flat level surface at the optimal dis-
tance from the screen or wall so you realize the size image
you want. (Avoid having bright room lighting or sun light
directly on the screen or wall where you’ll be projecting the
image.)
2. Connect the power cable, remove the lens cap and turn the
projector on. (If no input signal is available, the projector
will display a background image.)
3. Ensure that the projector is square to the screen.4. Move the projector left or right to center the image horizon-
tally on the screen.
5. To center the image vertically, lift the front edge of the pro-
jector and press the One-Touch Tilt button on the front side
of the projector to release the Front Adjustable foot.
(There is approximately 10 degrees of up and down adjust-
ment for the front of the projector.)
6. If  the  projected image does not appear square to the screen
then use keystone correction for proper adjustment.
7. Adjust the size of the image using the Zoom lever on the
lens.

WARNING
•Installing your projector on the ceiling must be done by a
qualified 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 severely 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
projector 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 pro-
jector cabinet or your remote control to correct the orientation.
(See page E-35.)
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
your remote control to correct the orientation. (See page E-35.)

Use common RCA cables (not provided) to connect your VCR, laser disc player or document camera to your projector.
To make these connections, simply:
1. Turn off the power to the projector and VCR, laser disc player or document camera.
2. Connect one end of your RCA cable to the video output connector on the back of your VCR or laser disc player, connect the other
end to the Video input on your projector. Use an audio cable (not supplied) to connect the audio from your VCR or laser disc player
to your audio equipment (if your VCR or laser disc player has this capability). Be careful to keep your right and left channel
connections correct for stereo sound.
3. Turn on the projector and the VCR or laser disc player.
NOTE: Refer to your VCR or laser disc player owner’s manual for more information about your equipment’s video output require-
ments.
