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 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.

No matter Blank Timer is activated or disabled, you can press any key except ENTER on the remote control, or ENTER on the projector to restore the picture.

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.
