This projector is equipped with a lens shift function for adjusting the position of the projected image by using the LENS
SHIFT buttons (→ page 19). The lens can be shifted within the range shown below.
NOTE:
• Please do not use the lens shift function when projecting portrait images. Please use it with the lens in the center.

* The lens shift range is the same for ceiling installation.
(Example) When using to project on a 150" screen
According to the "Table of screen sizes and dimensions" (→ page 155), H = 127.2"/323.1 cm, V = 79.5"/201.9 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.5 × 79.5"/201.9 cm ≈
39.8"/101 cm, downwards approximately 39.8"/101 cm (when the lens is at the center position). Adjustment range in
the horizontal direction: the projected image can be moved to the left 0.15 × 127.2"/323.1 cm ≈ 19.1"/48 cm, to the
right approximately 19.1"/48 cm.
* Figures differ by several % because the calculation is approximate.
