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. t 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) t Make sure there is plenty of space for ventilation around and under the projector. t 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. t 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: Its best to position the screen directly in front of the room. If its placed diagonally in a corner, its 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), youll need to square-up the sides of image by pressing the Keystone button (also on page 7). If youll be projecting from overhead, youll 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. (Youll also need to select ceiling projection mode in the projectors Advanced menu.)

Displaying an Image

Once youve connected the projector to your computer or other equipment, youre 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 youre projecting video, first plug in and turn on your VCR, DVD player, or other video source. (If youre projecting from a computer, go to step 2.) 2. To turn on the projector, first connect one end of the power cord to the projectors power inlet on its left side.

40 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
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 youre 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 youre 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 youre 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: t Make sure the cables are connected correctly, as described in Chapter 1. t Make sure the Power light is green and not flashing and the lens cap is off. t If youve connected more than one input source, you may need to press the Source button on top of the projector or the Computer, Video, or S-Video button on the remote control to select the source you want to use. (Allow a few seconds for the projector to sync up.)

The lamp cover is not closed securely or the lamp has burned out. Secure the lamp cover or replace the lamp; see page 11 for instructions. The projector is too hot. Turn it off and let it cool before using it. Also make sure nothing is blocking the projectors air intake vent. If it continues to overheat, clean the air intake vent; see page 10 for instructions. The projector lamp has turned off automatically because the projector has overheated. Let it cool for a few minutes, then turn it back on. Also make sure nothing is blocking the projectors air intake vent. If it continues to overheat, clean the air intake vent; see page 10 for instructions.

Using the Remote Control
The remote control lets you access projector features from anywhere in the roomup 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.
flashing red at 2-second intervals
Shutting Down the Projector
When youve 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.

Cleaning the Projector Case
Before you clean the projector case, turn off the projector and unplug the power cord. t To remove dirt or dust, wipe the outside with a soft, dry, lint-free cloth. t 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. t 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.

3. To clean the vent, EPSON recommends using a small vacuum cleaner designed for computers and other office equipment. If you dont have one, use a dry, lint-free cloth. If the dirt is difficult to remove, replace the air intake vent. You can purchase the part from your dealer, or by calling EPSON at (800) 873-7766, or by visiting the EPSON Store at (U. S. sales only). In Canada, please call (800) 873-7766 for dealer referral.

Replacing the Lamp

The projection lamp typically lasts for about 1500 hours of use. It is time to replace the lamp when: t The projected image gets darker or starts to deteriorate. t The Error light on top of the projector is flashing red in 1-second intervals. t The LAMP REPLACE message appears on the screen when the projector lamp comes on (after about 1500 hours of use). To maintain projector brightness and image quality, replace the lamp as soon as possible after you see the message. Note: To view the number of hours your lamp has been used, check the About menu. Request replacement lamp part number ELPLP13. Follow these steps to replace the lamp: 1. Turn off the projector, let it cool down, and unplug the power cord. 2. Allow the projector to continue cooling for at least one hour (if it has been on). Warning: Let the lamp cool before replacing it. To avoid premature lamp failure, do not touch the glass portion of the lamp assembly. Caution: Make sure the lamp cover is securely fastened; the Error light flashes and the projector lamp wont turn on if the cover is open. 8. Follow the instructions on page 10 to access the projectors About menu and reset the lamp counter to zero. 7. Insert the lamp cover as shown and press it back into place.
