Hiding the image
In order to draw the audience's full attention to the
presenter, you can use BLANK on the projector or
remote control to hide the screen image. Press any
button on the projector or remote control to restore the
image.
The word 'BLANK' appears at the lower right
corner of the screen while the image is hidden. When
this function is activated with an audio input
connected, the audio can still be heard.
You can set the blank time in the
SYSTEM SETUP:
Basic > Blank Timer
menu
to let the projector return
the image automatically after a period of time when
there is no action taken on the blank screen.
Once BLANK is pressed, the projector enters Economic mode automatically.
Do not block the projection lens from projecting as this could cause the blocking object to
become heated and deformed or even cause a fire.
