Power Management
NOTE: The Power Management

This feature preserves lamp life by automatically turning the 
lamp off after no signal has been detected for five minutes. 
1When the input signal is interrupted, the message “No signal” 
appears with a counter that starts at 5 and counts down to 0.
2After the counter reaches 0, the lamp is turned off, the Ready 
indicator turns off, and the fans run for 90 seconds. During 
this cool down time, the lamp cannot be turned on.
3After 90 seconds, the Ready indicator blinks and the lamp can 
be turned back on. 
The lamp is automatically turned on when the input signal is 
re-connected or any button on the remote or keypad is 
pressed.

MAINTENANCE & TROUBLESHOOTING
This section describes how to:
clean the lens
clean the air filter
replace the projection lamp 
replace the batteries in the remote
troubleshoot the projector
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, and don’t 
apply the cleaner directly to the lens.
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.
Cleaning the Fan Intake Filters
The fan intake filters on the bottom of the projector catch dust 
and particles in the air. If the filters become clogged, the projector 
does not cool properly and may malfunction. To prevent this, 
clean the filters after every 100 hours of use.
1Turn off the projector and unplug the power cord.
2Turn the projector upside down and remove the two filters by 
pulling the latches up.

grasp the handle and pull the module out (Figure 17). Dispose 
of the lamp module in an environmentally proper manner.

Troubleshooting
Problem: The projector is not running
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 the projector is turned on.
Problem: Projector is running, but nothing appears on projec-
tion screen
Make sure you have removed the lens cap on the projection 
lens at the front of the projector.
Check the projector ’s lamp to ensure that it is securely con-
nected in the lamp module. Make sure the lamp cover is 
installed. See “Replacing the Projection Lamp” on page 36.
Problem: Only the start-up screen displays
Verify that the cables are connected correctly. See page 7 and 
page 8 for connection procedures.
Make sure that the cables do not have any bent pins.
Verify that the proper input source is connected. See “Source 
(keypad only) or Computer and Video (remote only)” on 
page 16.
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 or EGA compatible.

1Open “My Computer” icon, the Control Panel folder and 
then the Display icon.
2Click the Settings tab.

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 22 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 menu. Refer to “H Position/V 
Position” on page 20.
Be sure the projector is at a 90 degree angle to the screen.
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 4.6 feet (1.8 m) from 
the projector.
Check the projection lens to see if it needs cleaning.

ting. See “Fine sync” on page 22.
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 22, 
“Tint” on page 30 and “Contrast” on page 31. 
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 36.

A minor power surge may cause the lamp to shut off. Unplug 
the projector, wait at least a minute, then plug it back in.
