Runco Reflection CL-410 Owner's Operating Manual page 21

Note:
• The projector lens should be centered on the screen. If the horizontal line
passing through the lens center is not perpendicular to the screen, the image
will be distorted, making viewing difficult.
• For an optimal image, position the screen so that it is not in direct sunlight
or artificial light. Light falling directly on the screen washes out the colors,
making viewing difficult. Close the curtains and dim the lights when setting
up the screen in a sunny or bright room.
• A polarizing screen cannot be used with this projector.

Projection Distance
The Projection Distance (also known as 'throw distance') is the distance the projector
needs to be from the screen for a given screen size. This is measured from the projector's
lens to the screen, in a straight line (not the center of the screen).
For the CL-410, the formula is:
For example, if your screen width is 100", the projection distance range would be
between 137" and 167"
