release the function: LASER , #2 , #5 , PAGE +/PAGE -.
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 on screen.
Hiding the image
In order to draw the audience's full attention to the presenter, you can use ECO BLANK
on the remote control to hide the screen image. When the function is activated with an
audio input connected, the audio can still heard.
You can set the blank time in the System Setup: Basic > Operating Settings >
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 5-minute increments.
If the preset time spans are not suitable for your presentation, select Disable .
No matter Blank Timer is activated or disabled, you can press most of the keys on the
projector or remote control 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.
