Correcting Computer Images
If you’ve connected a computer and the image doesn’t look right, or it 
doesn’t fit properly on the screen, press the 
Enter button on the 
projector or the 
Enter/Auto button on the remote control. This 
automatically resets the projector’s tracking, sync, resolution, and 
position settings. You must be projecting a computer image for this 
button to have any effect. Additionally, if the 
Auto Setup option in 
the Signal menu is set to 
OFF, the Auto function will not work. See 
page 59.
Adjusting the Volume
You can use the Vol- and Vol+ buttons on the remote control to 
increase or decrease the volume for the projector’s built-in speaker. 
On the PowerLite 77c, you can also use the buttons on the projector 
to control the volume. Press the   button to increase the volume, or 
the   button to decrease it. A volume gauge appears on the screen 
while the volume is being adjusted.
note
You can also adjust the 
volume using the projector’s 
Settings menu. See page 61 
for details.
You must adjust the volume 
separately for each input 
source.

Shutting Down the Projector
When you’ve finished using the projector, follow the recommended 
procedure to shut it down:
1. If you’re using a computer, shut it down first; otherwise you may 
not be able to see your computer’s display to shut it down 
properly.
2. To turn off the projector, press the P 
Power button on the 
projector or remote control.
You see this confirmation message: 
(If you don’t want to turn it off, press 
any other button or wait a few 
seconds until it disappears.)
3. Press the P 
Power button again. The projector beeps twice, the 
lamp is turned off, and the power light turns orange.
With Epson’s exclusive Instant Off
® technology there’s no 
cool-down period, so you can pack up and go immediately after 
turning off the projector.
If you want to turn the projector on again, press the P 
Power 
button.
4. Press up on the blue foot release lever and lower the projector to 
retract the front adjustable foot.
5. Close the 
A/V Mute slide.
6. Unplug the power cord.
7. Turn off and disconnect any equipment 
plugged into the projector.
8. If you won’t be using the projector for 
awhile, store it in the soft case 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 P 
Power button. You 
can turn sleep mode on or of
f 
through the Extended menu. 
See page 64.
Turn off  this product when 
not in use to prolong the life 
of the projector.
caution
To avoid damaging the 
projector or lamp, never 
unplug the power cord 
when the power light is 
green or flashing orange.

Using the Remote Control
The remote control lets you access your projector’s features from 
anywhere in the room—up to 20 feet away. For example, you can turn 
the projector on and off, freeze the presentation, zoom in on a portion 
of your image, and access the menu system. (The projector menus let 
you adjust many projector settings; see Chapter 4.)
If you’re using a computer and you’ve connected a USB cable 
as described in Chapter 1, you can use the remote control to change 
slides in your presentation.
When using the remote control, stand within 20 feet of the projector. 
Point the remote control either at the front or back of the projector or 
at the screen (the projector’s front sensor can detect signals bounced 
off the screen). Press the button for the function you want to use.
This chapter covers the following information:
■Controlling the picture and sound
■Changing slides in a presentation
■Replacing the remote control batteries 
						

							44Using the Remote Control
Controlling the Picture and Sound
You can use the remote control to select your source, temporarily turn 
off the picture and sound, freeze the action, or zoom in on the picture. 
Make sure you have set up your projector and connected any 
equipment as described in Chapter 1.
Switching Between Picture Sources
If you’ve connected your projector to more than one computer and/or 
video source, you can use the 
Source Search button on the projector 
or remote control to switch between the different sources.  
After you select a source, the screen goes dark for a moment before the 
image appears. The name of the selected source (such as 
Computer or 
S-Video) appears briefly on the screen. 
Adjusting the Color Mode
You may want to adjust the color mode to select a different setting 
that is appropriate for the image you’re projecting and the 
environment in which you’re projecting it. Press the 
Color Mode 
button on the remote control.
If you’re projecting computer or RGB video images, the default color 
mode is 
Presentation, which is appropriate for full-color 
presentations in bright rooms.  
						

							Using the Remote Control45
The following table lists the color modes available.  
You can also use the projector menu system to change the color mode 
in the Image menu (see page 56).
Color mode Description
Photo Best for projecting still images with vivid color in a 
bright room (computer input only).
Sports Best for watching TV in a bright room (component, 
S-video, or composite video input only).
Presentation Use when you’re projecting a full-color presentation in 
a bright room.
Text Use when you’re projecting a black and white 
presentation in a bright room.
Theatre Use when projecting movies in a dark room.

sRGB Use when projecting computer images conforming to 
the sRGB color standard.
Blackboard Choose this fixed color mode when you need to 
project against a green chalkboard. 
						

							46Using the Remote Control
Turning Off the Picture and Sound
Press the A/V Mute button on the remote control or use the A/V 
Mute
 slide on the projector to turn off the image and sound and 
darken your screen. This is useful if you want to temporarily re-direct 
your audience’s attention without the distraction of a bright screen. 
■To turn off the picture and sound, press the A/V Mute button or 
close the 
A/V Mute slide on the projector. The screen goes dark.
■To turn the image and sound back on, press the button again, or 
open the 
AV Mute slide.
You can create an image, such as a company logo or a picture, to 
display on the screen whenever you press the 
A/V Mute button. See 
page 67 for more information.
Stopping Action 
Press the Freeze button to stop the action in your video or computer 
image and keep the current image on the screen. The sound will 
continue, however. Also, because the source continues to transmit 
signals, you won’t resume the action from the point you paused it.
Press the 
Freeze button again to restart it.

Zooming Your Image
Follow these steps to zoom in on a portion of the image:
1. Press the 
E-Zoom + button on the remote control.

2. Use the four “arrow” buttons on the remote control to position 
the crosshair in the area you want to enlarge.
3. Continue pressing the 
E-Zoom + button to enlarge the selected 
area up to 4 times.
4. While the image is enlarged, you can:
■Use the arrow buttons to pan about.

5. When you’re done, press the 
ESC button to return to the original 
size.

Changing the Image’s Aspect Ratio
If you’re projecting a widescreen format image, you can use the 
Aspect button on the remote control to change the aspect ratio. 
Follow these steps:
1. Press the 
Aspect button once to change the aspect ratio to 16:9 
for widescreen format.
2. Press it again to return to 4:3 aspect ratio.
Changing Presentation Slides
You can use the remote control to click through slideshow-style 
presentations (such as PowerPoint) from up to 20 feet away. This 
gives you more flexibility, since you don’t need to stand near your 
computer to change slides. 
To change slides with the remote control, make sure you have 
connected your computer to the projector with a USB cable as 
described on page 21. 
To advance slides in a PowerPoint presentation in Slide Show mode, 
press the 
Page up button on the remote control. Press the Page 
down
 button to go back a slide.
note
You must be projecting 
component, composite, or 
S-Video images to change the 
aspect ratio. 
You can also change the 
aspect ratio using the 
projector’s Signal menu. See 
page 58 for details. 
						

							Using the Remote Control49
Replacing the Batteries
The remote control uses two AA alkaline batteries. Follow these steps 
when you need to replace them:
1. Press in the tab to remove the battery cover.
2. Remove the old batteries, then insert the new ones as shown.
3. Replace the battery cover. (It should click into place.)
caution
When replacing batteries, 
take the following 
precautions:
■Replace the batteries as 
soon as they run out. If a 
battery leaks, 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 the batteries if you 
won’t be using the remote 
control for a long period of 
time. 
note
The remote control 
automatically shuts off when 
it detects a button being 
pressed more than 30 seconds. 
This conserves battery life. It 
can be helpful, for example, 
when the remote is in a 
carrying case and the 
Power 
button is accidentally pushed.
