Projector Positioning
The projected image becomes larger as the distance between the unit and screen
increases. The minimum image size is about 36 inches (93cm) diagonally at a distance of
about 1.2m (3.9 feet) and the maximum size is about 200 inches (508cm) at a distance of
6.8m (22.3 feet) from the screen. The HT201 and HT211 do not have zoom capability so
they must be positioned at the exact distance from the screen.]
