enlarge the image. Press the

top zoom button on the remote to increase the size, or the

button on the projector or bottom zoom button on the

remote to decrease it.

Focus

If the image still isn't large enough, you may need to move the

projector farther away from the screen. You can also use the

buttons on the remote control to zoom in on a

E-Zoom

portion of the image.

Adjusting the Height of Your Image

If the image is too low on the screen, you can raise it by

adjusting the front foot:

1. Stand behind the projector. Press up on the blue foot

release lever and lift the front of the projector.

2. Once the image is positioned where you want it, release the

lever to lock the foot in position.

3. If necessary, you can fine-tune the height by turning the

projector's rear feet.

Raising the projector causes the image to distort or

"keystone," but you can manually correct the shape as

described in the next section.

Adjusting the Image Shape

In most cases, you can maintain a rectangular image by

placing the projector directly in front of the center of the

screen with the base of the lens level with the bottom of the

screen.

Even if the projector is slightly tilted (within a range of 45°

up or down), the projector's automatic keystone correction

function detects and corrects vertical keystone distortion.

Projector tilted up

It takes about one second after projection starts for the image

to be corrected. During this time, a vertical keystone

correction gauge appears on the screen.

If your image is still distorted, you can correct it using either

of these methods:

If the image has two parallel

sides but is wider on the top,

bottom, left, or right, you can

correct it using the

buttons on the projector's

control panel or the Keystone

menu (see the next section).

If the image has no parallel

sides, you can adjust its shape

using Quick Corner

page 8).

You cannot use both keystone

correction and Quick Corner at

the same time.

Using Keystone Correction

To adjust your image when it is wider on one side, do the

following:

Look at the shapes of the icons on the projector's four

keystone buttons. Press the button whose icon is the

opposite of the shape of your screen image. Continue

pressing the button until you are satisfied with the

shape of the image.
