of time.
Doing so can result in these images being temporarily sus-
tained on the surface of the LCD panel.
If this should happen, continue to use your projector. The
static background from previous images will disappear.
The STATUS indicator’s light depends on the lamp mode.
NOTE: To turn the projector on by plugging in the power cable, use
the menu and enable the “Auto Start” feature. (See page E-36.)

lighting is stabilized.

net to select “Video” (VCR, document camera, or laser disc player),

display the image.
Or press the “Menu” button on the remote control or the cabinet and
use the menu to select your video source: “Video”, “S-Video” or
“RGB”.
3. Adjust the Image Size and the Focus
Use the Zoom lever to adjust the image size, then use the Focus ring
to obtain the best focus.
Use the “Magnify” button (+) or (-) on the remote control to make
the image larger up to 400%.
See page E-27.
4. Turning off the Projector
First press the “ON/STAND BY” button on the projector cabinet or
the “POWER OFF” button on the remote control for a minimum of
two seconds. The power indicator will glow orange. After the pro-
jector turns off, the cooling fans keep operating for 60 seconds.
