Operation 41
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 5-minute increments.
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.
