Positioning the Projector

Follow these guidelines:

❏ Place the projector on a sturdy, level surface, between

2.6 and 36 feet from the screen. Image size generally increases with distance, but may vary depending on the position of the zoom ring and other settings.

27 to 36.1 ft

2.6 to 3.5 ft7 to 9.5 ft

❏ Place it within 10 feet of an electrical outlet or extension

cord and 5 feet of your computer or video source.

❏ Allow space for ventilation around and under the projector.

❏ To avoid a keystone shaped image (an image that is wider

on one side), place the projector directly in front of the center of the screen, facing the screen squarely.

❏ If possible, place the projector level with the bottom of the

screen.

If you place the projector too far below the screen, you may have to tilt it up by extending the front adjustable foot (see page 7). This causes the projected image to lose its shape, but the projector automatically compensates. If the image is still not square, adjust it manually by pressing the buttons (see page 7) or using Quick Corner (see page 8).

If you place the projector higher than the bottom of the screen, the image will be square, but it won’t fill the screen.

Calculating Image Size and Projection Distance

Use the formulas below to find out how large the image will be when you know the distance from projector to screen, or to find out how far from the screen to place the projector if you want an image of a certain size. Since you can change the image size by rotating the zoom ring, formulas are given for calculating both minimum and maximum sizes.

Note: Formulas given here apply only when the image is not tilted. If you tilt the image up by extending the projector’s foot or using electronic keystone correction, your image size may vary.

Distance from screen

Keystone

Standard Lens

To determine the diagonal size of an image (in inches) when you know the projection distance:

❏ Maximum diagonal size =

((2.54

projection distance) / 100) × 36) + 2.13

❏ Minimum diagonal size =

((2.54

projection distance) / 100) × 26.84) + 1.29

To determine the projection distance (in inches) when you know the diagonal size of the screen image:

❏ Maximum projection distance =

((diagonal size – 1.29) / 26.84)

× 100 / 2.54

❏ Minimum projection distance =

((diagonal size – 2.13) / 36)

Middle Throw Lens (V12H004M03)

× 100 / 2.54

To determine the diagonal size of an image (in inches) when you know the projection distance:

❏ Maximum diagonal size =

((2.54

projection distance ) / 100) × 27.42) + 1.49

Minimum diagonal size = ((2.54

projection distance) / 100) × 20.48) + 1.1

To determine the projection distance (in inches) when you know the diagonal size of the screen image:

❏ Maximum projection distance =

((diagonal size – 1.1) / 20.48)

× 100 / 2.54

❏ Minimum projection distance =

((diagonal size – 1.49) / 27.42)

Long Throw Zoom Lens (V12H004L05)

× 100 / 2.54

To determine the diagonal size of an image (in inches) when you know the projection distance:

❏ Maximum diagonal size =

❏ Minimum diagonal size =

❏ Maximum projection distance =

Starting Up the Projector

If you turn on your computer or video equipment before the projector, the projector automatically selects the connected source. If you turn on the projector first or you have multiple sources connected, you may have to switch to the desired source manually (see “Selecting the Image Source” on page 5).

Turning On the Projector

1. Remove the lens cap.

2. Plug in the projector.

3. Wait a few seconds until the projector’s P

flashing and turns orange.

4. Press the red P

Power button on top of the projector or on

the remote control.

Note: If you’re using the remote control, make sure batteries are installed and the power switch on the side of the remote control is turned on.

The projector’s P

power light flashes green as it warms up,

and an image begins to appear after about 30 seconds. When the P

power light stops flashing and remains green,

the projector is ready for use.

Wa rn ing : Never look into the lens when the lamp is on. This can damage your eyes.

5. If you’ve connected a Windows-based computer to the projector, you may see a New Hardware Wizard saying your computer has found a plug-and-play monitor; if so, click

Cancel.

What To Do If You See a Blank Screen

If you see a blank screen or a blue screen with the message No Signal after turning on your computer or video source, try the following:

❏ Make sure the cables are connected correctly.

❏ Make sure the power light is green and not flashing and the

lens cover is off.

❏ Try restarting your computer.

❏ Press the correct

Source button on top of the projector or

on the remote control. (Allow a few seconds for the projector to sync up after pressing the button.)

If you’re using a PC laptop:

❏ Hold down the Fn key and press the function key that lets

you display on an external monitor. It may have an icon such as or it may be labeled

CRT/LCD. Allow a few

seconds for the projector to sync up after pressing it. Check your laptop’s manual or online help for details.

On most systems, the or

CRT/LCD key lets you

toggle between the LCD screen and the projector, or display on both at the same time.

❏ Depending on your computer’s video card, you might need

to use the Display utility in the Windows

Adjusting the Image

Once you see your image, you may need to make certain adjustments.

Focusing and Zooming Your Image

Use the focus ring on the projector to sharpen the image.

Use the zoom ring on the projector to reduce or enlarge the image. Move the tab toward the toward the

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

E-Zoom buttons on the remote control to zoom in on a

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 the blue foot release lever up and lift the front of the projector.

W to make it bigger, or

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 40° up or down), the projector’s automatic keystone correction function detects and corrects vertical keystone distortion.

Corrected imageProjector tilted up Projector tilted down

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

Keystone keys on the

projector’s control panel or the Keystone menu (see “Using Keystone Correction” on page 7).

❏ If the image has no parallel

sides, you can adjust its shape using Quick Corner (see page 8).

™

Quick Corner correction

You cannot use both keystone correction and Quick Corner at the same time.

2. Once the image is positioned where you want it, release the lever to lock the foot in position.

3. If necessary, you can finetune the height by turning the projector’s rear feet.

Using Keystone Correction

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

❏ Look at the shapes of the icons on the

projector’s four

Keystone buttons.

Press the button whose icon is the opposite shape of your screen image. Continue pressing the button until you are satisfied with the shape of the image.
