The fans sound during
standby.
• WhenStandbyModeoftheEfcientModemenuintheInstallationmenuisset
to Speaker Out or Monitor Out, the fans rotate at very low speed during standby
after plugging the power cord (with 5 second high speed rotation at the beginning)
and after turning off the lamp. This is to cool down the projector operating various
functions during standby and is not a malfunction.
Abnormal sound is
heard.

Images are not 3D.
* Use commercially
available 3D glasses
supporting the DLP™
Link™ system.
No 3D glasses are
supplied with the
projector.
• Isthe3Dmodeoftheprojectorsetproperlyfortheimage?
 Set 3D in the Picture menu of the projector properly for the image (Auto , Side by
Side , Top and Bottom , or Frame Sequential ).

 The 3D glasses work by receiving signals of the images being viewed. Check that
there is no obstacle between the 3D glasses and the screen.
• Areyouviewingimagesfromaveryclosedistance?
 Viewing images from a very close distance may not obtain the 3D effect. View
images from a proper distance.
