提示
z 所列出的投影距离可能有 ±5 % 的误差。
此外，当使用 [KEYSTONE] 时，距离被校正为小于指定的屏幕尺寸。
z 投射率基于投影期间使用的投影画面尺寸为 2.03 m (80") 时的值。
Note
z A ±5 % error in listed projection distances may occur.
In addition, when [KEYSTONE] is used, distance is corrected to become smaller than
the specified screen size.
z The throw ratio is based on the value during projection with the projected image size
of 2.03 m (80").
未列在上表中的安装尺寸，请使用下面的公式进行计算。请检查投影画面尺寸 SD (m)，
使用下面的公式确定投影距离 (L)。
Setting-up dimensions which are not given in the above table can be calculated
using the formulas below. Check the projected image size SD (m) and use the
following formula to determine projection distance (L).
