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

							28Using the Projector
Resizing the Image
Some computer images need to be resized to display in the projector’s 
native resolution. If only part of your computer image is displayed, 
you can correct it with the 
Resize button. 

Press the Resize button on the projector’s control panel (or on 
the remote control). The screen image is automatically 
compressed.

Continue pressing the Resize button to pan around the screen in 
the original resolution. 
If you’re projecting from video equipment, pressing the 
Resize 
button switches the aspect ratio between 4:3 and 16:9. If you’ve 
zoomed in on your image (using the 
E-Zoom button on the remote), 
you can press the 
Resize button to return it to the original display 
size. 
Adjusting the Tracking and Synchronization
If you’re projecting from a computer and displaying an image that 
contains a lot of detail (such as the text of a letter), you may notice one 
or more vertical stripes or bands, or some of the characters may look 
heavy or blurred. You can increase the clarity by pressing the   
Auto 
button on the projector’s control panel (or the Auto button on the 
remote control). This resets the projector’s tracking, sync, and 
position settings. 
If further adjustment is needed, you can correct the image manually 
using the 
Tracking and Sync buttons as described on page 77.

							Using the Projector29
Controlling the Projector
While giving your presentation, you may want to switch between 
picture sources, adjust the volume, or temporarily turn off the picture 
and sound. Follow the instructions below to access theses features 
from your projector’s control panel. You can also access these features, 
plus many others, using the remote control as described in Chapter 3. 
Switching Between Picture Sources
If your projector is connected to more than one computer and/or 
video source, you can use the buttons on the control panel (or remote 
control) to switch between the different sources. 
On the projector’s control panel, press the 
Computer/YCbCr button 
to switch between computer sources and component video. Press the 
Video button to switch between standard (composite) video and 
S-Video. 
After you select a source, the screen goes dark for a moment before the 
image appears.
Adjusting the Volume 
If your presentation includes sound, you can adjust the volume from 
the projector’s control panel. 

To increase the volume, press on the right side of the Volume 
button.

To reduce the volume, press on the left side of the Volume 
button.

							30Using the Projector
Turning Off the Picture and Sound 
You can use the A/V Mute button on the control panel to darken your 
screen and turn off the sound. 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. 
The screen goes dark.

To turn the picture and sound back on, press the button again.
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’ve connected a computer or laptop and it’s displaying only 
through the projector (the computer’s monitor is disconnected or 
turned off), shut down the computer 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 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.)
note
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 53 for instructions.
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.

3. Press the Power button again. The power light flashes orange for 
about a minute and a half 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. If you extended the front foot, press the foot adjust button to 
retract it.
5. Replace the lens cap and unplug the power cord.
6. If you’re using a VCR or other video source, turn it off after you 
turn off the projector.
7. Disconnect all equipment, and store the projector in a protective 
case.
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 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. 
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:

							34Using 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.
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.
