control is on. (→ pages 25, 26, 27)
• Ensurethatthelampcoverisinstalledcorrectly.(→ page 86)
• Checktoseeiftheprojectorhasoverheated.Ifthereis insufcientventilationaroundtheprojectororifthe
room where you are presenting is particularly warm, move the projector to a cooler location.
• Checktoseeifyoucontinuetousetheprojectorforanother100hoursafterthelamphasreachedtheendof
its life. If so, replace the lamp. After replacing the lamp, reset the lamp hours used. (→ page 80)
• Thelampmayfailtolight.Waitafullminuteandthenturnonthepoweragain.
• Set[FANMODE]to[HIGH ALTITUDE]whenusingtheprojectorataltitudesapproximately 5500feet/1600
meters or higher. Using the projector at altitudes approximately 5500 feet/1600 meters or higher without setting
to [HIGH ALTITUDE] can cause the projector to overheat and the projector could shut down. If this happens,
wait a couple minutes and turn on the projector. (→ page 74)
If you turn on the projector immediately after the lamp is turned off, the fans run without displaying an im-
age for some time and then the projector will display the image. Wait for a moment.
• Ensurethatthe[OFFTIMER]or[AUTOPOWEROFF]isoff.(→ page 76, 77)
• UsetheCOMPUTER1,theCOMPUTER2,the VIDEOortheS-VIDEObuttonontheremote controltoselect
your source (Computer, Video or S-Video). (→ page 29) If there is still no picture, press the button again.
• Ensureyourcablesareconnectedproperly.
• Usemenustoadjustthebrightnessandcontrast.(→ page 62)
• Removethelenscap.

• BesuretoconnecttheprojectorandnotebookPCwhiletheprojectorisinstandbymodeandbeforeturning
on the power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on unless connected to the projector
before being powered up.
* If the screen goes blank while using your remote control, it may be the result of the computer’s screen-saver
or power management software.

• Condensationmayformonthelensiftheprojectoriscold,broughtintoawarmplaceandisthenturnedon.
Should this happen, let the projector stand until there is no condensation on the lens.
•
Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 5500 feet/1600
meters or lower. Using the projector at altitudes less than approximately 5500 feet/1600 meters and setting to [HIGH
ALTITUDE] can cause the lamp to overcool, causing the image to flicker. Switch [FAN MODE] to [AUTO]. (→ page 74)
• Checkthecomputer’sresolutionand frequency.Makesurethattheresolution youaretryingtodisplayis
supported by the projector. (→ page 97)
