IMPORTANT SAFEGUARDS Caution regarding usage of the projector ■ When using the projector, ensure not to sub- ject 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, ensure to unplug the power cord from the wall outlet, and disconnect any other cables connected to it. ■ Do not use the projector by holding the lens. ■ When you are not to use the projector for a long time, or storing the projector, ensure to attach the lens cap to the projector (See page 9.). ■ 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 projector 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, ensure to use an appropriate power cord for the country you are in. Temperature monitor function ■ If the projector starts to overheat due to setup problems or blockage of the air vents, " " and " " will illuminate in the lower left corner of the picture. If the temperature continues to rise, the lamp will turn off, the temperature warning indicator on the pro- jector will blink, and after a 90-second cooling- off period the projector will enter the standby mode. Refer to "Maintenance Indicators" on page 54 for details. Info • The cooling fan regulates the internal temperature, and its performance is automatically controlled. The sound of the fan may change during projector operation due to changes in the fan speed. This does not indicate malfunction. • Do not unplug the power cord during projection or cooling fan operation. This can cause damage due to rise in internal temperature, as the cooling fan also stops. -8
