Cleaning the Projector
Periodically clean the projector exterior, lens, intake vents, and exhaust vents on a regular basis.
Important!Before cleaning the projector, be sure to unplug it from the power outlet and make sure it is 
cooled down completely.
Wipe the exterior of the projector with a soft cloth that has been moistened in a weak solution of water 
and a mild neutral detergent. Be sure to wring all excess moisture from the cloth before wiping.
Never use benzene, alcohol, thinner, or any other volatile agent for cleaning.
Carefully wipe the lens with a commercially available lens cloth or optical lens paper, like those for 
eyeglasses or camera lenses. When cleaning the lens, do not apply undue force and take care to avoid 
damaging the lens.
Dust and dirt tend to collect around the intake vents. Because of this, you should use a vacuum 
cleaner to clean away accumulated dust and dirt periodically as shown below.
Important!zContinued use of the projector after dust has accumulated around the intake vents can cause 
overheating of internal components and lead to malfunction.
zCertain operating conditions also can cause dirt and dust to accumulate around the 
projector’s exhaust vents. If this happens, use the same procedure as that described above to 
clean the exhaust vents.

Troubleshooting
Indicators keep you informed about the current operational status of the projector. The following 
shows what the indicators look like when operation is normal.
When a warning message appears on the projection screen, or when the POWER/STANDBY, LIGHT, 
and TEMP indicators are lit or flashing in a pattern other than those shown above, it means that a 
projector error has occurred. For details, see “Error Indicators and Warning Messages” (below).
Warning messages and indicators let you know what the problem is when a projector error occurs.
When an error occurs, wait until the fan stops before unplugging the AC power cord. If you unplug the 
AC power cord while the fan is still operating, an error may occur when you plug the AC power cord 
back in.

Projector Troubleshooting
ProblemCause and Recommended Action
Power does not turn on.zIf the POWER/STANDBY indicator is not lit, the AC power cord is not connected 
correctly. Connect the AC power cord correctly.
zIf the TEMP or LIGHT indicator remains flashing or lit, it means some type of error 
has occurred. See “Error Indicators and Warning Messages” (page 44).
No image is projected or 
the projected image is 
abnormal.zThe computer or video device connected to the projector is not turned on or it is 
not outputting a video signal. Make sure the connected computer or video device 
is turned on, and perform the required operation on it to output a video signal.
zThe correct output source is not selected on the projector. On the projector, select 
the correct input source that corresponds to the connected device.

Appendix
When performing an operation on the remote controller, point it at the remote control signal receiver 
on the back or front of the projector. The following illustration shows the range of the remote controller 
signal.
Remote Controller Range
zThe range of the remote controller may be narrower and/or shorter than that shown on the right 
(Back) when there is a special AV cable plugged into the AV terminal on the back of the projector.
zThe allowable distance between the remote controller and the projector is less when there is a 
sharp angle between the remote controller and the remote control signal receiver.
Important!To avoid running down the batteries, store the remote control unit so its keys are not pressed 
inadvertently.
