Important Safety Warnings
• Unplug the projector immediately if you detect an abnormal smell or see smoke.
• Do not look directly into the lighted lens; doing so will cause severe eye injury.
•Do not look directly at the laser beam or point the laser at a person’s eyes. Doing so can
cause serious vision problems.
•Keep small children away from the projector. Children can be severely burned by the hot lens.
Also, children are more likely to look directly into the lens.
• Never touch the lens or the lamp when hot or warm; doing so will cause a severe burn. Unplug the
projector and allow it to cool for 45 minutes before replacing the lamp or storing the projector.
• Do not service the unit yourself; doing so could cause injury.
• Do not operate the projector near water or in a humid area. Do not place drinks on or near the
projector; doing so could cause a burn or short an electrical circuit.
• Do not block the ventilation openings in the projector. Place the projector so that there is adequate
air circulation
• Keep the air filter clean.
• Do not place the projector on a shelf or on any other unstable surface.

5Position the Projector.
•Position the projector on a level and stable surface. Determine the distance the projector will be
from the screen. (See “Positioning the Projector” on page 6.)
•Adjust the angle of the projection by positioning the foot adjusters. (Se e"Adjusting the
Projector Angle" on page 7.)
6Turn on the Input Devices and select the Input Signal.
•Press either the Input button on the projector control pad or the Video/RGB buttons on the
remote control to select the signal to be projected.
•The selected input signal source displays in the lower right section of the screen.
7Adjust the image size.
