Automatic Incoming Signal Detection Function
The Search button on the remote control and the Source Search button on the control panel allow
the user to switch between images from different pieces of equipment connected to the projec-
tor each time either one of the two buttons is pressed. While the projector is detecting a source,
it displays the Search in Progress screen to show the user which source being detected.
Instant-Off Function
This lets the user to turn the projector off quickly by reducing the cool-down period. When the
Power button on the remote control or the control panel is pressed, the lamp is turned off and
then the end of power-off process is indicated by two beeps. The fans stops soon after the beep
regardless of the internal temperature.
Fan Speed Switch Function
When using the projector at high altitude (higher than 1,500 meters above sea-level), the fan
speed should be increased to cool the projector efficiently and extend the lamp life since air
density is low at high altitude. Select High for the Fan Speed in the Extended Menu to increase the
fan speed.
Image Shift Function
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.
