User’s Guide

The distance from the lens to the screen determines the actual image size. 
The recommended distance and projection distance values given below are 
for when the projector is fitted with a standard lens or an optional wide 
zoom lens. If the projector has been fitted with an optional lens, refer to the 
documentation provided with the lens.

While referring to the following table, position the projector so that the 
images are projected onto the screen at the optimum size. The values 
should be used as a guide for setting up the projector. The actual values 
will vary depending on projection conditions and the zoom setting.

* When installing against a wall, leave a space of 20 cm (7.9 in.) or more 

between the projector and the wall.
