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. Turn off and disconnect any equipment plugged into the 
projector. 
2. To turn off the projector, press the red P
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 30 seconds as the projector cools down. After 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. If you extended the adjustable front foot, press up on the blue 
foot release lever to retract it.
5. Replace the lens cap and unplug the power cord.
6. If you’re using a remote control, set its on/off switch to 
OFF. This 
conserves battery power.
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 want 
to start projecting again, 
press the Power button. If 
you are done using the 
projector, unplug the power 
cord. To turn off sleep mode, 
see page 74.

Giving Your Presentation
The projector includes a number of tools to enhance your 
presentation. All of them can be accessed using the remote control, 
which lets you operate the projector from anywhere in the room—up 
to 33 feet away. 
You can use the remote control to adjust the picture and sound 
(page 49), or as a pointer or drawing tool to highlight your 
presentation (page 54). You can also use it as a wireless mouse when 
projecting from a computer (page 56); this lets you easily change 
slides, for example, when giving presentations in PowerPoint. 
To further enhance your presentation, you can create a customized 
screen to display a picture or company logo (page 57), and then use it 
as the startup screen or the screen you see when you press the 
A/V Mute button. 
This chapter covers:
■Activating and using the remote control
■Controlling the picture and sound
■Highlighting your presentation
■Operating your computer with the remote control
■Creating your own startup screen []
■Controlling multiple projectors

Activating and Using the Remote 
Control
The remote control has an on/off switch on its side, as shown. Before 
using the remote, make sure batteries are installed as described on 
page 48, then push up on the on/off switch to turn it on. 
Turn off the remote control before transporting or storing it; this 
prevents the batteries from discharging if something presses against 
one of the buttons. 
Here are some additional tips:
■Point the remote control either at the front or back of the 
projector, or at the screen.
■Stand within about 30 feet of the projector. If you want to operate 
the projector from a greater distance, a remote control cable set is 
available (see page 6).
■When presenting in a darkened room, press the  light button to 
make the buttons on the remote light up temporarily. 
■Avoid using the remote under bright fluorescent lamps or in 
direct sunlight, or the projector may not respond properly.
On/off switch
note
If a button is pressed longer 
than 60 seconds, the remote 
control stops operating to 
conserve power. When you 
release the button, normal 
operation resumes.

Using the Navigation Buttons
The remote control has various buttons that let you navigate the 
projector’s help and menu systems; they also let you use the drawing 
tools to highlight your presentation. If you’ve connected a computer, 
the buttons can be used in place of your computer’s mouse, letting 
you walk about freely while controlling your presentation.
For details on using the buttons to control specific features, see the 
following sections: 
■to navigate the projector’s menu system, see page 64
■to use the projector’s help system, see page 102
■to highlight your presentation, see page 54
■to use the remote control in place of your computer’s mouse,

Replacing the Batteries 
If the projector stops responding to the remote control, check the 
following:
■Make sure the remote control’s on/off switch (shown on page 46) 
is in the 
ON position. 
■Press the  light button and check to see if the buttons on the 
remote control light up. (If you’re in a bright room, you may not 
be able to see them light.)
If the buttons do not light up, replace the batteries as described below: 
1. Turn the remote control over. 
2. Press down on the ridges at one 
end of the battery cover as you 
slide the cover off.
3. Install two AA batteries, inserting 
the flat (negative) ends in first.
4. Slide the cover back in place.
caution
When replacing batteries, 
take the following 
precautions:
■Replace the 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 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 
projector for a long period of 
time.

Controlling the Picture and Sound
You can use the remote control to preview and select your picture 
sources, temporarily turn off the picture and sound, freeze the action, 
zoom in on the picture, display a picture-in-picture image, and adjust 
the volume. 
Switching Between Picture Sources
If your projector is connected to more than one computer and/or 
video source, you can switch between the different sources: 
■On the projector’s control panel, there are two Source buttons: 
Press the 
Computer/DVI button to switch between equipment 
connected to the 
Computer and DVI ports. Or press the 
Video/BNC button to switch between equipment connected to 
the 
Video, S-Video, and BNC ports. 
■On the remote control, there are six Source buttons. Use them to 
switch between equipment connected to the port identified on 
each button. (The 
EasyMP button is not functional with the 
PowerLite 7800p.)
Note that the 
Computer and BNC ports can be set up to use different 
input signals (for example, Analog RGB or RGB Video)—so if you 
have equipment connected to one of these ports, it’s important to 
make sure the correct signal is selected to match the equipment you’re 
using. You can change the input signal settings using the projector’s 
menu system; see page 72. 
After you select a source, the screen goes dark for a moment before the 
image appears.
note
You can use the projector’s 
menus to fine-tune the 
picture and sound quality as 
described in Chapter 4.

that source appears blank. 
2. Press one of the 
Source buttons on the remote control to switch 
to the desired source, and press 
Enter to change the source and 
exit the screen. Or press 
ESC to exit the preview screen without

Turning Off the Picture and Sound 
You can use the A/V Mute button on the remote control to turn off 
the image and sound and darken your screen. (If you’ve connected an 
external monitor to the projector, it will continue displaying.) This 
feature is useful if you want to temporarily redirect your audience’s 
attention without the distraction of a bright screen. 
■To turn off the picture, press the A/V Mute button. The screen 
goes dark. 
■To turn the image back on, press the button again.
You can also have an image, such as a company logo, display on the 
screen whenever you press the 
A/V Mute button (see page 57).
Stopping Action
You can use the remote control to stop the action in your video or 
computer image. 
■Press the Freeze button to stop the action and keep the current 
image on the screen. The sound continues. 
■Press the Freeze button again to restart it.
Zooming Your Image 
You can zoom in on a portion of the image using the E-Zoom buttons 
on the remote control.
1. Press the 
E-Zoom  button on the remote control. 
You see a crosshair indicating the center of the zoom-in area.
2. Use the  pointer button to position the crosshair.

picture-in-picture window on the screen. This window can display 
video from equipment connected to either the 
Video or S-Video 
port. 
Setting Up the P-in-P Image
Before starting, make sure the computer or video equipment for your 
main image is connected to the 
DVI, Computer, or BNC port(s), and
