Lens shifting range
This projector is equipped with a lens shift function for adjusting the position of the projected image by using the LENS
SHIFT buttons (

page
). 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 when one among
the lens units, NP16FL, NP17ZL, NP18ZL, NP19ZL, NP20ZL, NP21ZL or NP31ZL is fixed on. For using the lens unit NP39ML,
select [TYPE] for [LENS POSITION] in [INSTALLATION(2)] in [SETUP] on the onsceen menu for moving the lens at the appropriate
position.
Legend: V “Vertical” refers to the screen height and H “Horizontal” refers to the screen width. The lens shift range is
expressed as a ratio of height and width, respectively.

* 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
), 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.
