| L: Distance to screen H: Height from the edge of screen to center of lens NOTE: Illustrations show the projector installed using optional ceiling bracket. This illustration is not drawn to scale. |
 |
| * This distance is especially recommended for ceiling-mounted use and other permanent installations. NOTE: Values shown are approximate. The value for L (distance to screen) varies slightly depending on the zoom lens characteristics. When the shortest projection distance is used, a small amount of distortion may occur in the image due to the zoom lens characteristics. |
| Calculation of the projection distance For a screen size different from the above, use the equation below to calculate the projection distance. |

| Aspect ratio | 4 : 3 | |

L (m) = (diagonal screen size in inches)
x 0.0292 – 0.036 L (m) = (diagonal screen size in inches) x 0.0351 – 0.044 |
| NOTE: Distances calculated with the above equations will include a slight error. |
