Only after you press the "ON/STAND BY" button on the projector

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.)
NOTE: Immediately after turning on the projector, screen flicker
may occur. This is not a fault. Wait for 3 to 5 minutes until the lamp
lighting is stabilized.
2. Select the Computer or Video Source
Press the Source button on the remote control or the projector cabi-
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

to obtain the best focus.
Use the "Magnify" button (+) or (-) on the remote control to make
the image larger up to 400%.

IMPORTANT:
• The projector should be unplugged if it will not to be used for an
extended period.
• To turn off the image and sound briefly (five minutes or less), use
the "Picture Mute" button instead of turning the projector off and
on.
• The projector will display a black, blue image or logo if no input
signal is present.
• Do not turn the projector off and then immediately back on. The
projector needs to cool for 60 seconds before it can be restarted.
CAUTION
Avoid displaying stationary images for a prolonged period
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.
CAUTION
Do not turn off the main power or unplug the power cable
from the wall outlet under any one of the following circum-
stances. Doing so can cause damage to the projector:
• Immediately after the power cable is plugged into the wall
outlet (when the POWER indicator has not changed to a
steady orange glow).
• Immediately after the cooling fan stops working (The cool-
ing fan continues to work for 60 seconds after the pro-
jector is turned off with the POWER button).
