Cleaning the Lens
Follow these steps to clean the projection lens:
1Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
Avoid using an excessive amount of cleaner.
Abrasive cleaners, solvents or other harsh chemicals might 
scratch the lens.
2Lightly wipe the cleaning cloth over the lens in a circular 
motion.
3If you don’t intend to use the projector immediately, replace 
the lens cap.
Replacing the Projection Lamp
WARNING: To avoid burns, 
allow the projector to cool for at 
least 30 minutes before you open 
the lamp module door. Never 
extract the lamp module while the 
lamp is operating.
The lamp hour counter in the Status menu counts the number of 
hours the lamp has been in use. After 1,900 hours, the message 
“Change Lamp” temporarily appears on the screen when the pro-
jector is turned on. Replace the lamp when the brightness is no 
longer acceptable. You can order new lamp modules from your 
InFocus dealer. See “Accessories” on page 44 for information.
Follow these steps to replace the projection lamp:
1Turn off the projector by unplugging the power cord. 
2Wait 30 minutes to allow the projector to cool thoroughly.
3Use a screwdriver to remove the seven screws on the back of 
the projector (Figure 24). 
						

							36
Maintenance & Troubleshooting
WARNING: Be extremely careful
when removing the lamp module.
In the unlikely event that the bulb
ruptures, small glass fragments
may be generated. The lamp
module is designed to contain
these fragments, but use caution
when removing the lamp module.

IGURE 24
Removing the screws on the lamp door 
CAUTION: Never operate the
projector with the lamp door open
or removed. This disrupts the air
flow and causes the projector to
overheat.
4Loosen the three captive screws on the outside of the module.

tor.
8Tighten the three screws on the outside of the module.

Maintenance & Troubleshooting
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 opera-
tion.
Follow these steps to replace the batteries:
1Turn the remote face down in your hand.
2Slide the battery cover off the end of the remote.
3Remove the old batteries and dispose of them in an environ-
mentally proper manner.
4Install two new AA alkaline batteries. Make sure you install 
each in the correct direction.
5Slide the battery cover back on the remote.
Using the Security Lock 
The projector has a security connector for use with a PC Guardian 
Cable Lock System (Figure 27). See “Optional Accessories” on 
page 44 for ordering information. Refer to the information that 
came with the lock 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 lamp is switched on.
Check the projector ’s lamp to ensure that it is securely con-
nected in the lamp module. See “Replacing the Projection 
Lamp” on page 35.
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 23 for more infor-
mation.
Problem: The screen resolution is not right
Make sure the computer ’s video card is set for a resolution of 
no greater than 1280x1024. 
Problem: Image isn’t centered on the screen
Move the projector to reposition the image.
Reposition the image using the software. Refer to “Horizontal 
position” on page 29 and “Vertical position” on page 29.
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 9 
through page 11 for connection procedures.
Verify that the proper input source is connected and active. See 
“Source (keypad only) or Comp and Video (remote only)” on 
page 21.

Maintenance & Troubleshooting

You might need to turn everything off and power up the 
equipment again in the proper order. Refer to your com-
puter ’s documentation to determine the correct order.
Make sure your laptop’s external video port is turned on. See 
the “Portable and Laptop Activation Chart” on page 46 or 
your computer ’s manual for details.
Make sure your computer ’s video board is installed and con-
figured correctly.
Make sure your computer has a compatible video board. The 
projector isn’t CGA, EGA or SXGA compatible.
If you’re using Windows 98:
1Open “My Computer” icon, the Control Panel folder and 
then the Display icon.
2Click the Settings tab.
3Verify that the Desktop area is set to 1280x1024 or less.
Problem: Image is too wide or narrow for screen
Adjust the zoom or projector placement.
Adjust the resolution of your video card if it’s greater than 
1280x1024.
Problem: Image is out of focus
Turn the projection lens to focus the image.
Make sure the projection screen is at least 3.3 feet (1 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 Projec-
tion off in the Controls menu. The image should immediately 
return to forward projection. See “Rear Projection” on 
page 31.

Problem: the projector displays vertical lines, “bleeding” or 
spots
Adjust the brightness. See “Brightness” on page 23.
Check the projection lens to see if it needs cleaning.

Adjust volume.
Verify audio/input connections. Make sure you have selected 
the proper audio source. See “Audio Source Select” on 
page 26.
Adjust audio source.
Problem: Image is “noisy” or streaked
Try these steps in this order.
1Deactivate the screen saver on your computer.
2Tu r n  
Auto Image off and then back on again. See “Auto 
Image” on page 27. 
3Tu r n  
Auto Image off and adjust the synchronization and track-
ing manually to find an optimal setting. See “Manual Sync” 
on page 28 and “Manual Tracking” on page 28.
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 moni-
tors, there are often differences between the computer image 
and the projected image. Adjust the brightness, tint and/or 
contrast from the Display menu. See “Brightness” on page 23, 
“Tint” on page 23 and “Contrast” on page 23. 
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 35.
