Important Safety Information
WARNING: Never look into the projector lens when the lamp is turned on; the bright light can damage your eyes. Never let children look into the lens when it is on. Never open any cover on the projector, except the lamp and filter covers. Dangerous electrical voltages inside the projector can severely injure you. Except as specifically explained in this User’s Guide, do not attempt to service this product yourself. Refer all servicing to qualified service personnel.
WARNING: The projector and its accessories come packaged in plastic bags. Keep plastic bags away from small children to avoid any risk of suffocation.
Caution: When you replace the lamp, never touch the new lamp with your bare hands; the invisible residue left by the oil on your hands may shorten the lamp life. Use a cloth or glove to handle the new lamp.

Displaying and Adjusting
the Image
Whether you’re presenting from a computer or video equipment, you need to follow some basic steps to display your image on the screen.
Follow the guidelines in this chapter for:
■Positioning the projector
■Turning the projector on and off
■Selecting the image source
■Troubleshooting display problems
■Adjusting the image
15
note
You can mount the projector on the ceiling, or place it behind a translucent screen for rear projection. See page 105 for details.
Positioning the Projector
If the projector isn’t already installed in the room you’re using, you’ll probably want to place it on a table in front of the screen. This lets you stand in the front of the room, face the audience, and remain close enough to the equipment to be able to control it. Try to leave as much space as possible between the projector and the screen to get a good-size image.
Use the figure below to help you determine placement. Image size increases with distance, but can vary depending on how you position the zoom ring and whether you’ve adjusted the image with other settings.
Also keep these considerations in mind:
■Place the projector on a sturdy, level surface.
■Make sure there is plenty of space for ventilation around and under the projector. Do not set the projector on top of anything that could block the vents.
■Make sure the projector is within 10 feet of a grounded electrical outlet or extension cord.
16 Displaying and Adjusting the Image
Ideally, you should place the projector directly in front of the center of the screen, facing it toward the screen squarely. The base of the lens should be at about the level of the bottom of the screen.
Projector
Screen
note
After positioning the projector, you may want to connect a Kensington MicroSaver® anti-theft device to the lock port on the projector. You can purchase this from Epson; see
page 13.
If you place the projector below screen level, you’ll have to tilt it up by extending the front adjustable foot. This causes the image to become “keystone” shaped, but you can correct the distortion by pressing the buttons on the projector. See page 25 for detailed information about correcting the image shape.
For instructions on installing the projector in a permanent location, such as a theater or conference room, see page 105.
Turning the Projector On and Off
Make sure your projector and any computer or video equipment are connected as described on page 39. Turn on your connected equipment before starting the projector so it can automatically detect and display the image source. If you turn on the projector first, or have multiple pieces of connected equipment, you may have to select the image source manually (see page 20).
Displaying and Adjusting the Image 17
note
You can set the projector to automatically turn off the lamp and enter “sleep mode” when it has not received any signals or the A/V Mute slide remains closed for a period of time. This conserves electricity, cools the projector, and extends the life of the lamp. To enable sleep mode, see page 75.
Turning On the Projector
Follow these steps to turn on the projector:
1. Open the A/V Mute slide (lens cover).
2.Plug one end of the power cable into the projector, and the other end into an electrical outlet.
The Ppower light turns orange.
Power light
18 Displaying and Adjusting the Image
3.Press the Ppower button on the remote control or on top of the projector.
The projector beeps once and the Ppower light flashes green as the projector warms up, then an image begins to appear. When the Ppower light stops flashing and remains green, the projector is ready for use.
4. If you are prompted to enter a password, see page 69.
warning
Never look into the lens when the lamp is on. This can damage your eyes, and is especially dangerous for children.
Using the Direct Power On Function
The Direct Power On function enables faster setup. The projector will start up automatically when you plug it in; you won’t have to press the Ppower button.
Follow these steps to enable Direct Power On:
1.Press the Menu button on the remote control and select the
Extended menu.
2.Choose Operation and press Enter.
3.Choose Direct Power On and press Enter.
4.Highlight On and press Enter.
5.Press Esc or Menu to exit. The setting will take effect the next time you plug in the projector.
note
If a power outage occurs when Direct Power On is enabled and the projector is plugged in, the projector will restart when the power is restored.
Displaying and Adjusting the Image 19
note
Lamp life results will vary depending on mode selected, environmental conditions, and usage.
Turn off this product when not in use to prolong the life of the projector.
Shutting Down the Projector
This projector incorporates Instant Off technology. To turn it off, you can press its Ppower button as described below, unplug it, or turn off a power switch that supplies power to the projector. You don’t have to wait for the projector to cool off first.
1.To turn off the projector, press the Ppower button on the remote control or projector.
You see a confirmation message.
(If you don’t want to turn it off, press any other button.)
2.Press the Ppower button again. The projection lamp turns off and you can unplug the power cord.
If you want to turn the projector on again, make sure the orange Ppower light is not flashing, then press the Ppower button.
3.If you extended the adjustable front foot, press up on the foot release lever to retract it.
4.Close the A/V Mute slide.
note
To focus and adjust the image, see page 23. If a projected image fails to appear, see page 21 for help.
Selecting the Image Source
Selecting the image source lets you switch between images input from different pieces of connected equipment (such as a computer or DVD player).
If you don’t see the image you want, press the Search button on the remote control or the Source Search button on the projector until you see the image you want to project.
20 Displaying and Adjusting the Image
You can also use the Source buttons on the remote control to switch between devices connected to the ports identified on each button. (The LAN button does not work with the PowerLite 84.)
Troubleshooting Display Problems
Follow these guidelines if you’re having trouble displaying an image.
You Can’t Project an Image
If you don’t see the image you are trying to project, try the following:

The Projector and Notebook Don’t Display the
Same Image
If you’re projecting from a notebook, and you can’t see your image on the projection screen and on your computer at the same time, follow these guidelines.
If you’re using a PC notebook:
■On most systems, there’s a function key that lets you toggle
between the LCD screen and the projector, or display on both at the same time. It may be labeled CRT/LCD or have an icon such as 
. You may have to hold down the Fn key while pressing it. Allow a few seconds for the projector to sync up after changing the setting.
■If the function key doesn’t permit you to display simultaneously on both screens, you should check your monitor settings to make sure both the LCD screen and the external monitor port are enabled.
From the Control Panel, open the Display utility. In the Display Properties dialog box, click the Settings tab, then click Advanced. The method for adjusting the settings varies by brand; you may need to click a Monitor tab, then make sure the external Monitor port is set as your primary display and/or enabled. See your computer’s documentation or online help for details.
If you’re using Mac OS X:
You may need to set up your system to display on the projector screen as well as the LCD screen. Make sure your projector is connected and follow these steps:
1.From the Apple® menu, select System Preferences, then select
Displays.
2.Click Detect Displays.
3.Make sure the VGA Display or Color LCD dialog box is selected.

■To focus or zoom your image, see page 24.
■If the image isn’t square, see page 25.
■If a computer image displays incorrectly, see page 27.
■If you need to fine-tune the image and/or sound, see page 61.

Adjusting the Height of Your Image
If the image is too low on the screen, you can use the front adjustable foot to raise it.
1.Stand behind the projector. Press the foot release lever up 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 or level of the image by turning the projector’s adjustable rear feet.
Raising the projector causes the image to distort or “keystone,” but you can correct the shape as described on page 25.
Focusing and Zooming Your Image
Turn the focus ring on the projector to sharpen the image.
Turn the zoom ring on the projector to reduce or enlarge the image.

24 Displaying and Adjusting the Image
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 portion of the image. See page 33 for instructions.
Adjusting the Image Shape
In most cases, you can maintain a square or 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 30° up or down), the projector has an automatic keystone correction function that detects and corrects vertical keystone distortion.
