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. The word 'BLANK' appears in the 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. The length of time can be set from 5 to 30 minutes in
If the preset time spans are not suitable for your personation, select Disable.
No matter Blank Timer is activated or disabled, you can
press any key except PAGE

and LASER on the remote control to restore the picture.
Freezing the image
Press FREEZE on the remote control to freeze the image. The word 'FREEZE' will display in the upper left corner of the screen. To release the function, press any button on the projector or remote control.
Even if an image is frozen on the screen, the pictures are running on the video or other device. If the connected devices have active audio output, you will still hear the audio even though the image is frozen onscreen.
Once BLANK is pressed, the projector lamp 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.
