Do not block the ventilation holes Avoid using a thick-piled carpet or anything that covers the ventilation holes (exhaust/ intake); otherwise, internal heat may build up. Do not place a blocking object just in front of the lens Do not place any object just in front of the lens that may block the light during projection. Heat from the light may damage the object. Use the PIC MUTING key to cut off the picture. Do not use the Security bar for transporting or installation Usage at High Altitude When using the projector at an altitude of 1,500 m or higher, turn on "High Altitude Mode" in the INSTALL SETTING menu. Failing to set this mode when using the projector at high altitudes could have adverse effects, such as reducing the reliability of certain components. Notes on Use Note on carrying the projector The unit is manufactured using highprecision technology. When transporting the unit stored in the carrying case, do not drop the unit or subject it to shock, as this may cause damage. When storing the unit in the carrying case, disconnect the AC power cord and all other connecting cables or cards, and store the supplied accessories in a pocket of the carrying case. Note on the screen When using a screen with an uneven surface, a striped pattern may rarely appear on the screen depending on the distance between the screen and the projector or the zooming magnification settings used. This is not a malfunction of the projector. Use the Security bar at the rear of the projector for a purpose of preventing theft, by attaching a commercially available theft prevention cable for example. If you lift the projector by holding the Security bar, or hang the projector by using this bar, it may cause the projector to fall or be damaged. 8 Notes on Installation and Usage
