Connecting to a Video Device 
Follow the steps below to connect the projector to a VCR, DVD 
player, or any other video device that has RCA-style (composite video) 
connectors. Before starting, make sure the projector and your video 
device are turned off. 
1. Connect the yellow RCA plug on one end of the RCA video cable 
to the projector’s 
Video port. Connect the other end of the cable 
to the video-out port of your video source. 
2. To use the projector’s built-in speaker system, connect the RCA 
audio cable to the left and right 
Audio ports of the projector 
(insert the white plug into the 
L port and the red plug into the R 
port). Connect the plugs at the other end of the cable to the audio 
output ports of the video source. 
When done making the connections, turn to “Displaying and 
Adjusting the Image” on page 37 to start your presentation.
note
To connect using S-video or 
component (BNC) video, see 
the projector Administrator’s 
Manual.

Displaying an Image
Follow the steps below to turn on the projector and any connected 
equipment, and to display an image.
Turning On the Projector 
Follow these steps to turn on the projector:
1. Make sure the projector is plugged in and the lens cap is off. 
The power light on the projector’s control panel glows orange, 
indicating that the projector is receiving power but the lamp is not 
turned on. 
note
You can also set the projector 
to turn on automatically at a 
preset time. See page 45.

2. Press the red Power button on the control panel. You can also use 
the 
Power button on the remote control, but make sure batteries 
are installed and the remote control is turned on first. (For details, 
see page 50.)
The projector’s power light flashes green as the projector warms 
up, and the projection lamp comes on in about 30 seconds. (To 
turn off the lamp, see page 47.)  
Selecting the Image Source 
The screen you see when turning on the projector depends on which 
image source was selected when the projector was last used. If 
EasyMP.net was selected, you see the EasyMP.net main screen, as 
shown below; if a computer or video source was selected, you see a 
blue screen with the No Signal message.
If necessary, follow these steps to display the correct image:
1. If you’re presenting from a computer or video device, turn on the 
device. (If you’re projecting a video, press 
Play on the video 
device.)
2. If you’ve connected a computer that’s running Windows and it 
displays a New Hardware Found message saying that it has found 
a plug-and-play monitor, click 
Cancel.

Adjusting the Image and Sound
If the projector is already installed in a meeting room, you probably 
won’t need to make any adjustments. If you set up the projector 
yourself, check the following:    

To focus or zoom your image, see below. 

If the image is too high or too low, you can reposition it. See 
page 42.

If the image isn’t square, see page 43.

If only part of a computer image is displayed, you may need to 
press the 
Resize button. See page 44 for more information.

If you’re using an audio source, see page 44 to adjust the sound.
Focusing and Zooming Your Image
Rotate the focus ring to sharpen the image.
Rotate the zoom ring to reduce or enlarge the image.
If the image still isn’t large enough, you may need to move the 
projector farther from the screen.

Adjusting the Height of Your Image
You can adjust the height of the image using the lens shift knob and 
the projector’s feet.
Using the Lens Shift Knob
If possible, set the projector flat on a table and use the lens shift knob 
(instead of raising the projector’s feet) to position the image on-screen. 
This delivers the best-looking picture.
You won’t need to tilt the projector upward as long as you position it 
so that its lens is at least as high as the bottom of the screen, but no 
higher than the middle of the screen, as shown:
Use the lens shift knob to raise or lower the image. If the knob is 
recessed, press and release it to make it extend; then turn it clockwise 
or counterclockwise to move the image up or down. When you’re 
finished, press the knob back in.

Using the Projector’s Feet
If the image is still 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.
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 
proje ctor off to one side of the scree n, at an an gle. M ove 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.
caution
Do not hold the projector by 
the lens; this can damage it.

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 control panel. 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. 
Adjusting the Volume 
If you’ve connected an audio source, you can adjust the projector’s 
volume from the control panel. Hold the 
Shift button down while 
pressing the
 + or – side of the Volume button. You can also adjust the 
volume using the remote control.

Turning On the Projector Automatically
You can set the projector to turn on at a preset time. You can set either 
a specific time for the projector to come on, or you can set it to come 
on everyday or on certain days of the week.
When the projector comes on, it displays whichever source was 
selected when last used. (See page 39 for instructions on switching 
sources.) The only exception is if a scenario is set to begin playing 
automatically (see page 8); in this case, the projector automatically 
switches to EasyMP so that the scenario can begin playing.
Follow these instructions to set the timer:
1. Turn on the projector (page 38) and select EasyMP.net as the 
source (page 39). You see this screen:
2. Click the 
Easy Configuration icon, as shown above.
