Replacing the Batteries in the Remote 
Control
The life of the batteries depends on how often and how long you 
use the remote. Symptoms of low battery charge include erratic 
responses when using the remote and a reduced range of 
operation.
Follow these steps to replace the batteries:
 1. Turn the remote face down in your hand.
 2. Slide the battery cover off the end of the remote by pressing 
on it with the heel of your hand.
 3. Remove the old batteries.
 4. Install two new AAA alkaline batteries. Make sure you install 
each battery in the correct direction.
 5. Slide the battery cover back on the remote.
Using the Kensington Lock
The projector has a Kensington Security Standard connector for 
use with a Kensington MicroSaver Security System (Figure 26). 
Refer to the information that came with the Kensington System 
for instructions on how to use it to secure the projector.

Troubleshooting
Problem: Nothing on projection screen
Make sure that the power cord is properly connected to 
a fully functional AC electrical outlet. Make sure that 
the power cord is also properly connected to the 
projector.
If the projector is plugged into a power strip, make sure 
the power strip is turned on.
Make sure you have removed the lens cap on the 
projection lens at the front of the projector.
Make sure the projector is switched on.
Check the projector’s lamp to ensure that it is securely 
connected in the lamp module. See “Replacing the 
Projection Lamp” on page 46.
Make sure that the cables do not have any bent pins.
Problem: Color or text not being projected
You might need to adjust the brightness up or down 
until the text is visible. Refer to “Brightness” on 
page 32 for more information.
Problem: The screen resolution is not right
Make sure the computer’s video card is set for a 
resolution of no greater than 1024x768. 
Problem: Image isn’t centered on the screen
Reposition the image. Refer to “Horizontal position” 
on page 36 and “Vertical position” on page 37.
Be sure the projector is at a 90 degree angle to the 
screen.

Problem: Only the start-up screen displays
Verify that the cables are connected correctly. See 
page 13 through page 20 for connection procedures.
Verify that the proper input source is connected. See 
“Source (keypad only) or Computer and Video (remote 
only)” on page 30.
You might need to turn everything off and power up the 
equipment again in the proper order. Refer to your 
computer’s documentation to determine the correct 
order.
Make sure your laptop’s external video port is turned 
on. See the “Using Video Mirroring with a PowerBook 
Computer” on page 71 or your computer’s manual for 
details.
Make sure your computer’s video board is installed and 
configured correctly.
If you’re using Windows 3.x:
 1. In the Windows Program Manager, double-click the 
Windows Setup icon in the Main program group.
 2. Verify that the Display setting is 1024x768 or less.
If you’re using Windows 95:
 1. Open the “My Computer” icon, the Control Panel folder, and 
then the Display icon.
 2. Click the Settings tab.
 3. Verify that the Desktop area is set to 1024x768 or less.
 4.  Also check the following: 
Does your computer have a compatible video board? 
The projector isn’t CGA or EGA compatible.
Is your computer’s video port activated? This is 
especially true for laptop computers. See “Portable and 
Laptop Activation Chart” on page 61.

Problem: Image is too wide or narrow for screen
You might need to manually adjust the tracking to 
reduce or enlarge the projected image. Refer to 
“Manual Tracking” on page 36.
Adjust the resolution of your video card if it’s greater 
than 1024x768.
Problem: Image is out of focus
Turn the projection lens to focus the image.
Make sure the projection screen is at least 5 feet 
(1.5 m) from the projector.
Check the projection lens to see if it needs cleaning.
Problem: Image and menus are reversed left to 
right
Rear projection mode is probably turned on. Turn Rear 
Projection off in the Controls menu. The image should 
immediately return to forward projection. See “Rear 
Projection” on page 38.
Problem: the projector displays vertical lines, 
“bleeding” or spots
Adjust the brightness. See “Brightness” on page 32.
Check the projection lens to see if it needs cleaning.

Problem: Image is “noisy” or streaked
Try these steps in this order.
 1. Deactivate the screen saver on your computer.
 2. Turn 
Auto Image off and then back on again. See “Auto 
Image” on page 35. 
 3. Adjust the synchronization and tracking manually to find an 
optimal setting. See “Manual Sync” on page 36 and “Manual 
Tracking” on page 36.
The problem could be with your computer’s video 
card. If possible, connect a different computer.
Problem: Projected colors don’t match the 
computer or video player’s colors
Just as there are differences in the displays of different monitors, 
there are often differences between the computer image and the 
projected image.
Adjust the colors using the KODAK Image Manager. 
See “Kodak Menu” on page 42.
Adjust the brightness, tint and/or contrast from the 
Display menu. See “Brightness” on page 32, “Tint” on 
page 32 and “Contrast” on page 33. 
Problem: Lamp seems to be getting dimmer
The lamp begins to lose brightness when it has been in 
use for a long time. Replace the lamp as described in 
“Replacing the Projection Lamp” on page 46.
Problem: Lamp shuts off
A minor power surge may cause the lamp to shut off. 
Turn the projector off, wait at least a minute, then turn 
it back on.
