NEC MT 820 - Manual (Page 17)

Using A Tabletop Or Cart
1. Place your LCD projector on a flat level surface at the optimal
distance 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 horizontally on
the screen. (A)
5. To center the image vertically (B), lift the front edge of the projector
and press the buttons on the front of the projector, just above the
feet, to release the one-touch tilt feet. (There is approximately 10.5˚
of up and down adjustment for the front of the projector. )
