Positioning the Projector
The location in which you choose to set up your projector depends on the size of the room and your presentation style.
❏ Place the projector on a sturdy, level surface, within this distance from the screen:
3.3 to 36 feet in Wide mode
3.9 to 43.2 feet in Tele mode
(see page 6 for more information on these modes)
❏ Make sure there is plenty of space for ventilation around and under the projector.
❏ Make sure the projector is within 6 feet of a grounded electrical outlet or extension cord, and within 5 feet of your computer and/or video source.
❏ Place the projector directly in front of the center of the screen, facing it toward the screen squarely. Otherwise, your image will not be square.
Note
:
It’s best to position the screen directly in front of the room. If it’s placed diagonally in a corner, it’s much more difficult to aim the projector at the screen correctly and get a square image.
Most presenters find it convenient to place the screen in the front of the room with the projector back near the front of the audience, leaving ample room between the screen and projector to get a good-sized image. Then the presenter can stand in front of the room, facing the audience and control the equipment from there.
Use the figure below as a guideline to help you determine how far from the screen to place the projector. Your image size may not exactly match these sizes; its actual size depends on whether you have adjusted the image size setting (using keystone correction or the
Wide/Tele
button).
If you have to raise the projector by adjusting its feet
(described on page 6), you’ll need to square-up the sides of
image by pressing the
Keystone
If you’ll be projecting from overhead, you’ll get the bestlooking picture by mounting the projector upside-down, parallel to the ceiling, with the bottom of its lens level with the top of the screen. (You’ll also need to select ceiling projection mode in the projector’s Advanced menu.)
Displaying an Image
Once you’ve connected the projector to your computer or other equipment, you’re ready to turn on the projector, adjust the image, and give your presentation.
Turning On Your Equipment
Make sure your projector and other equipment are set up and connected correctly. Then plug in and turn on your equipment, as described below.
Note:
If you have more than one source connected, you may have to
switch to the one you want to use, as described on page 5.
Follow these steps to plug in and turn on your equipment:
1. If you’re projecting video, first plug in and turn on your
VCR, DVD player, or other video source. (If you’re projecting from a computer, go to step 2.)
2. To turn on the projector, first connect one end of the power cord to the projector’s power inlet on its left side.
40 ft.
8 ft.
4 ft.
distance from the screen
When projecting from a table, the ideal arrangement is to set the projector flat on its surface with the base of the lens at about the level of the bottom of the screen. This delivers the best-looking picture.
3. Connect the other end to a grounded electrical outlet.
The
Power
light on the projector turns orange, indicating that the projector is receiving power and is in sleep mode, but is not yet turned on.
4 - EPSON Powerlite 50c/70c 01/01
EPSON Powerlite 50c/70c
4. Remove the lens cap.
5. Press the red
Power
button on top of the projector. (You can also turn on the projector using the remote control, but you must turn on the remote control first.)
The
Power
light flashes green and then stays on. You see a blue screen with the message
No Signal
displayed.
Warning
Never look into the lens when the lamp is on. This can damage your eyes, and is especially dangerous for children.
6. If you’re projecting images from a computer, turn on your computer. In a few moments, you should see your computer display projected. (If a projected image fails to appear, see the next section for help.)
Note:
Windows only: If you see a New Hardware Found message saying that Windows has found a plug-and-play monitor, click Cancel.
7. If you’re projecting video, press the
Play
button. (If a projected image fails to appear, see the next section for help.)
Once you see your image, turn to page 6 for instructions on
focusing and making other image adjustments.
When you’re done with your presentation, shut down the
projector as described on page 8. Shutting down the projector
correctly prevents premature lamp failure and possible damage to the projector from overheating.
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, do one of the following:

5. If you’re using a VCR or other video source, turn it off after you turn off the projector.
6. Disconnect all equipment, and store the projector in a protective case.
Shutting Down the Projector
When you’ve finished using the projector, follow the recommended procedure to shut it down. This extends the life of the lamp and protects the projector from possible overheating.
Note:
If sleep mode is enabled and the projector has not received any input signals for 30 minutes, it automatically turns off the projector lamp and enters “sleep mode.” This conserves electricity, cools the projector, and extends the life of the lamp. In sleep mode, the Power light is orange. If you are done using the projector, unplug the power cord. If you want to start projecting again, press the Power button on the projector or the remote control.
1. If you’ve connected a computer or laptop and it’s displaying only through the projector, shut down the computer first; otherwise you won’t be able to see your computer’s display if you try turning it off after the projector.

button again. The
Power
light flashes orange for a couple of minutes as the projector cools down.
When the projector has cooled, the orange
Power
light stays on and the fan shuts off.
If you want to turn the projector on again, wait until the orange
Power
light stops flashing. Then press the
Power
button.
Using the Remote Control
The remote control lets you access projector features from anywhere in the room—up to 32 feet away. You must also be within a 30° horizontal and a 15° vertical angle from the infrared receiver at the front of the projector. You can use it to turn the projector on and off, zoom the image, display the projector menus, and other uses.
If you connected a mouse cable to the projector, you can also use the remote control as a wireless mouse to run your presentation.
Note:
You can aim the remote control at your projection screen and reflect the signal back into the sensor on the front of the projector, but this shortens the operating distance of the remote control.
Installing the Remote Control Batteries
The remote control operates the projector and lets you access its setup menus. You can also use it as a wireless mouse.
Follow these steps to install the batteries:
1. Press the tab to release the battery cover and lift it up to remove it.
2. Insert the two AA batteries included with the projector as shown.
3. Replace the battery cover.

Using the Remote Control as a Wireless
Mouse
Using the remote control as a wireless mouse gives you more flexibility; you don’t need to stay near your computer or the projector to run your presentation.
To use the remote control as a mouse, you must first connect a mouse cable between your computer and the projector.
Note:
When you connect the mouse cable, your computer mouse is disabled and you can’t use another external mouse with your desktop. However, you may still be able to use the built-in mouse pointer on a laptop.
Follow these instructions to use your remote control as a wireless mouse:

position (the remote control is turned off)
❏ Batteries are weak
❏ Bright ambient light, fluorescent light, or direct sunlight is shining into the remote control sensor

Enter
button. To double-click, press down twice on the
Enter
button.

Enter
button and then tilt it in the direction you want to drag.
❏ To right-click, press the

Cleaning the Projector Case
Before you clean the projector case, turn off the projector and unplug the power cord.
❏ To remove dirt or dust, wipe the outside with a soft, dry, lint-free cloth.
❏ To remove stubborn dirt or stains, clean the case using a soft cloth moistened with water and a neutral detergent. Dry it using a separate cloth.
❏ Do not use alcohol, benzene, thinner, wax, or other chemicals. These can damage the case.
Cleaning the Air Intake Vent
Clean the air intake vent after every 100 hours of use, or if the
Error
light on top of the projector turns red.
If the vent is not cleaned periodically, it can become clogged with dust, preventing proper ventilation. This can cause overheating and damage the projector.
