Operating Precautions
IN-10
● 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 “Setting Up the
Projector” in the User’s Guide.
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” in the User’s Guide.
 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.
● Power Supply to External Equipment (XJ-F Series Only)
Turning off projector power also cuts power being supplied to external equipment. Note that power
being supplied is also cut when the projector is turned off due to restarting by its self-check function or
Auto Power Off, due to some error, or for any other reason. Depending on the external equipment being
used, cut off of the power supply may cause data that is being edited to be lost or corrupted. Make it a
habit to frequently save data on external equipment being powered by the projector. Note that CASIO
COMPUTER CO., LTD. shall be held in no way liable for any loss or corruption of data.
● Observe the precautions below. Failure to do so can cause the battery to
explode or leak flammable liquid or gas.
