Attention
f Before setting up, read "Precautions for use" (x page 17).
Especially when the Fixed-focus Lens (Model No.: ET-DLE030) is used, install the projector so that its back plane is parallel to the screen,
making the projected image rectangular.
The vertical keystone distortion in moderate range can be corrected with the [POSITION] menu → [GEOMETRY] → [KEYSTONE] →
[VERTICAL KEYSTONE] (x page 90) even after the projector is installed. For the range that can be corrected, refer to "[GEOMETRY]
projection range" (x page 35).
f The geometric adjustment function cannot be used when projecting the input signal rotated by 90° while using PT-RW730 or PT-RW620.
When installing the projector, follow the following instructions so that distortion does not occur in the projected image.
g Use a flat screen.
