Epson Powerlite 715c Multimedia Projector Users Guide

							22Using the Projector6. Do one of the following:

If you’re presenting without a computer, you may see the 
EasyMP main screen. Use the 
Enter button on the remote 
control to select your presentation, then press 
Enter to start 
it. See Chapter 5 for more information. 
If a presentation starts automatically, you may need to press 
Enter to change slides. 

If you’re using a computer, turn it on or restart it. In a few 
moments, you should see your computer display projected. If 
you see an EasyMP screen or presentation instead, press the 
Source button on top of the projector to switch to the 
computer.
(Windows
® only: If you see a message saying that it has found 
a plug-and-play monitor, click 
Cancel.) 

If you’re projecting a video, press the Source button on top 
of the projector to switch to your video source, and press the 
Play button on your DVD player or other device.
If a projected image fails to appear, see the next section for help. 
Once you see your image, turn to page 24 for instructions on focusing 
and making other image adjustments. 
When you’re done with your presentation, shut down the projector as 
described on page 27. Shutting down the projector correctly prevents 
premature lamp failure and possible damage 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, try the following:

Make sure the cables are connected correctly, as described on 
page 12 (for laptops) or in Appendix A (for other systems).

Make sure the power light is green and not flashing and the lens 
cover is off. 

Try restarting your computer.

Press the Source button on top of the projector to select the 
correct source. (Allow a few seconds for the projector to sync up 
after pressing the button.)
If you’re using a PowerBook:

as well as the LCD screen. Follow these steps:
1. From the Apple menu, select 
Control Panels, then click 
Monitors and Sound.
2. Click the Arrange icon.
3. Drag one monitor icon on top of the other. 
If this option isn’t available, you may need to select one of the

							24Using the Projector
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 labelled 
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   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 Control Panel to make sure that both the 
LCD screen and external monitor port are enabled. See your 
computer’s documentation or online help for details.
Adjusting the Image
Once you see your image, you’ll need to make certain adjustments:

To focus or zoom your image, see page 25. 

If the image is too high or too low, you can reposition it. See 
page 25.

If the image isn’t square, see page 26.

If the projected image colors are obviously incorrect, you may 
need to adjust the 
Input Signal setting on the Video menu. See 
page 74 for more information. 
						

							Using the Projector25
Focusing and Zooming Your Image
Rotate the focus ring to sharpen the image.
Use the tab to rotate the lens ring and reduce or enlarge the image.
You can also change the image size by moving the projector closer to 
or farther away from the screen. You can use the 
E-Zoom button on 
the remote control to zoom in on a portion of the image. See page 33 
for instructions. 
Adjusting the Height of Your Image
If the image is too low, you can raise it by extending the projector’s feet. 
1. Stand behind the projector. Pull up the blue foot release levers 
and lift the front of the projector. This unlocks the feet.
2. Once the image is positioned where you want it, release the levers 
to lock the feet in position.
3. To fine-tune the height of the image, rotate the thumb wheels 
attached to the projector’s feet.
If the image is no longer square after raising it, see the next section.

caution
Do not hold the 
projector by the lens; 
this can damage it. 
						

							26Using the Projector
Adjusting the Image Shape
If the projected image isn’t square or has a “keystone” shape , do one or 
more of the following:

If your image looks like   or  , you’ve placed the 
projector off to one side of the screen, at an angle. Move it directly 
in front of the center of the screen, facing the screen squarely.

If your image looks like   or  , press the + or — side of 
the 
Keystone button to correct the shape of the image. After 
correction, your image will be slightly smaller.
You can also perform electronic keystone correction using the 
projector’s Setting menu. See page 79.

							Using the Projector27
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. 
1. If you’re using a computer, shut it down first.
2. To turn off the projector, press the red 
Power button on the 
projector or remote control. You see a confirmation message. (If 
you don’t want to turn it off, press any other button.)
3. Press the 
Power button again. The power light flashes orange for 
about a minute as the projector cools down. When the projector 
has cooled, the orange light stays on and the exhaust fan shuts off.
If you want to turn the projector on again, wait until the orange 
light stops flashing. Then press the 
Power button.
4. Replace the lens cap, retract the lens, and unplug the power cord.
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 the bag that 
came with it or in a protective case.
note
When 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. If you are done 
using the projector, unplug 
the power cord. If you want 
to start projecting again, press 
the Power button.

Using the Remote Control29
Using the Remote Control
The remote control lets you access your projector’s features from 
anywhere in the room—up to 30 feet away. You can use it to turn 
the projector on and off, zoom in on a portion of your image, and 
highlight your presentation. 
You can also use the remote control for EasyMP presentations without 
a computer. See Chapter 5 for more information about EasyMP.
If you’re using a computer and you’ve connected the mouse cable (as 
described in Chapter 1 or Appendix A), you can use the remote 
control as a wireless mouse.
This chapter covers the following information:

Turning on and using the remote control

Controlling the picture and sound

Highlighting your presentation

							30Using the Remote Control
Turning On and Using the Remote 
Control
Before using the remote control, you need to install its batteries and 
turn it on as described below. 
Installing Batteries 
Follow these steps to install or replace the batteries:
1. Press the tab to release the 
battery compartment cover.
2. Remove the cover and insert 
the two AA batteries included 
with the projector as shown.
3. Replace the battery 
compartment cover.
Turning On the Remote Control
Make sure batteries are installed. Then push up the on/off switch on 
the side of the remote control to turn it on.
If you want to make sure the batteries are good, press the round 
light button. The other buttons on the remote should light up 
temporarily. If they don’t, you need to change the batteries as 
described above.
Turn off the remote control before transporting it or storing it in a 
projector case. This prevents the batteries from discharging if 
something presses against one of the buttons.
caution
When replacing batteries, 
take the following 
precautions:

Don’t mix old and new 
batteries.

Replace batteries as soon as 
they run out. If the batteries 
leak, wipe away battery fluid 
with a soft cloth. If fluid gets 
on your hands, wash them 
immediately.

Do not expose batteries to 
heat or flame.

Dispose of used batteries 
according to local regulations.

Remove batteries if you 
won’t be using the projector 
for a long period of time.
