IMPORTANT SAFEGUARDS
Do not block the intake and exhaust vents.
■Allow at least 11 13/16 inches (30 cm) of space between the exhaust vent and the nearest wall or obstruction.
■Set up the projector where air will not stay near its exhaust vent. In order to avoid allow- ing the heat from the exhaust vent to enter the intake vent area, leave at least more than 11 13/16 inches (30 cm) of space between the intake vent and the surrounding walls or ob- jects.
■If the cooling fan becomes obstructed, a pro- tection circuit will automatically put the pro- jector into standby mode to prevent overheat damage. This does not indicate a malfunc- tion (See pages 69 and 70.). Remove the pro- jector power cord from the wall outlet and wait at least 10 minutes. Place the projector where the intake and exhaust vents are not blocked, plug the power cord back in and turn on the projector. This will return the projector to the normal operating condition.
Caution regarding usage of the projector
■When using the projector, take care not to subject it to hard impact and/or vibration, as this can result in damage. Take extra care with the lens. If you are not to use the projector for a long time, make cer- tain you unplug the power cord from the wall outlet, and disconnect any other cables connected to it.
■Do not carry the projector by holding the lens.
■When storing the projector, ensure you at- tach the lens cap or dustproof cap to the pro- jector. (See page 13.)
■Do not expose the projector to direct sunlight or near heat sources. The projector may change color or become deformed.
Other connected equipment
■When connecting a computer or other audio- visual equipment to the projector, make the connections AFTER unplugging the power cord of the projector from the AC outlet and turning off the equipment to be connected.
■Please read the operation manuals of the pro- jector and the equipment to be connected for instructions on how to make the connections.
Using the projector in other countries
■The power supply voltage and the shape of the plug may vary depending on the region or country you are using the projector in. When using the projector overseas, make sure you use an appropriate power cord for the country you are in.

Info
•The cooling fan regulates the internal tem- perature, and its performance is automati- cally controlled. The sound of the fan may change during projector operation due to changes in the fan speed. This does not indicate malfunction.
•Even if you unplug the power cord after projector operation, the cooling fan con- tinues to run for a while. When you place the projector into the storage case, make sure that the cooling fan has stopped.
Optional lens installation
■For installing an optional lens, refer to “At- taching the Optional Lens” on page 77 or the lens installation manual (supplied with the optional lens).
■Remove the optional lens when carrying the projector. Carrying the projector with an op- tional lens attached can cause the projector to be damaged by vibration or other factors.
