z 投影距离计算方法
z Projection distance formulas
如果使用的是本使用说明书中未列出的投影机画面尺寸， 请测量投影画面对角尺寸 SD （m） 。
然后使用提供的计算方法确定投影距离 （L1） ， 以及投影机顶部至屏幕底部边缘的距离 （A1） 。
通过确定 L1 和 A1，即可计算所有其他尺寸。通过以下计算获得的值均为近似值。
If you are using a projection screen size not listed in these Operating Instructions,
measure the diagonal screen size SD (m). Then use the calculation methods provided
to determine projection distance (L1) and the distance from the top of the projector
to the bottom edge of the screen (A1). Establishing dimensions L1 and A1 allows
you to calculate all other dimensions. Note that the values obtained in the following
calculations are approximations.
