| 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. |

|
L (mm) = (diagonal screen size in inches)
x 0.0296 – 0.039 L (mm) = (diagonal screen size in inches) x 0.0358 – 0.047 |
| NOTE: Distances calculated with the above equations will include a slight error. |

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. The value for H (the height from the edge of the screen to the centre of the lens) is the value when the horizontal optical axis shift function is not used. The value decreases when the horizontal optical axis shift function is used. For details,see Shift range on page 6. |
