regardless of the internal temperature.

speed should be increased to cool the projector efficiently and extend the lamp life since air
density is low at high altitude. Select

This allows the user to adjust the image position without moving the projector. The image
retains its original aspect ratio after it is moved. This function is useful when it is difficult to
set the projector straight in front of the screen.
After correcting keystone distortion and adjusting the zoom, a screen to select the image posi-
tion is displayed. The user can select one of nine image position settings on the screen.
Lens-Shutter Function
Users can interrupt or restart the projection by opening and closing the A/V mute slide of the
main unit front. Closing the slide when the projector is not in use protects the lens from dirt
and scratches. During projection, closing the A/V mute slide turns off both the audio and
image while keeping the power and the lamp on.
