Hiding the image In order to draw the audience's full attention to the presenter, you can use on the projector or Blank on the remote control to hide the screen image. Press any key 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. 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. CAUTION 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.
