Sony VPL ES3 Operating Instructions - Page 7

Very dusty, extremely smoky locations Blocking the ventilation holes Avoid installing the unit in a very dusty or extremely smoky environment. Otherwise, the air filter will become obstructed, and this may cause a malfunction of the unit or damage it. Dust preventing the air passing through the filter may cause a rise in the internal temperature of the unit. Clean the filter periodically. Unsuitable Conditions Do not use the projector under the following conditions. Standing the unit upright on one side Avoid using the unit standing upright on its side. It may cause malfunction. Tilting the unit to the right or left Avoid tilting the unit to an angle of 15°, and avoid installing the unit in any way other than placing it on a level surface or suspending from the ceiling. Such an installation may cause color shading or shorten the lamp life excessively. Avoid using a thick-piled carpet or anything that covers the ventilation holes (exhaust/ intake); otherwise, internal heat may build up. Placing 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 on the Remote Commander to cut off the picture. 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. 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. Notes on Installation and Usage 7
