 Keystone Correction and Image Quality
Performing keystone correction causes the image to be compressed before it is projected. This can
result distortion of the image or a loss of image quality. If this happens, change orientation of the
projector and/or screen so it conforms as much as possible to the illustration under "Placing the
Projector on a Desk or on the Floor" (page 36).
If image quality is the highest priority, turn off keystone correction and position the projector so it is
pointed straight at the screen.
 Even if your projector is still within the warranty period, you will be charged for repair if a problem is
due to running the projector non-stop for very long periods (like 24 hours) or if the projector was set
up and used without following the "Setup Precautions" (page 38).
 Use under high ambient temperature or in environments subjected to large amounts of dust, oil
smoke, tobacco smoke, or other types of smoke can shorten the replacement cycles and require
more frequent replacement of the optical engine and other components. Note that you are charged
for such replacement. For details about replacement cycles and fees, contact an authorized CASIO
service center.
 Condensation
Moving the projector from a cold room to a heated room, turning on a heater in a cold room, and other
similar conditions can cause condensation (fogging) to form on the projector lens and/or inside the
projector, which will make the projected image appear out of focus and can lead to malfunction and
other trouble. If this happens, turn off the projector and wait for a while until the condensation clears
naturally. When it does, you will be able to project images normally.
 Disposing of batteries
Make sure that you dispose of used batteries in accordance with the rules and regulations in your local
area.
 Be sure to follow all applicable local laws and regulations, and do not dismantle the
projector when disposing of it.
