Ⅵ Overlaying projected images (when zoom
lens is in use)
ⅷ Projecting images by stacking projectors
The lens shift feature enables you to use up to three
stacked projectors at the same time.
Stacking the projectors enhances the brightness level,
and helps to project images that are sufficiently bright
even when the venue is relatively big or bright.
CAUTION:
● When the projectors are stacked together during use,
ensure that the installation site is sufficiently strong
and there is proper air cooling around the projectors.
Take the necessary measures to prevent the
projectors from toppling or falling off so as to ensure
safety during emergency situations, such as
earthquakes, and to prevent accidents from occurring.
For details, please consult your authorized dealer.
ⅷ Projecting images by arranging projectors
side by side
The lens shift feature enables you to use up to two
projectors that are arranged side by side.
Arranging two projectors side by side enhances the
brightness level, and helps to project images that are
sufficiently bright even when the venue is relatively big or
bright.
When projecting images by arranging the projectors side
by side, adjust the shift amount of both projectors
accordingly to superimpose the images.
CAUTION:
● When using the projectors by arranging them side by
side, ensure that the installation site is sufficiently
strong and there is proper air cooling around the
projectors. For details, please consult your authorized
dealer.
Ⅵ When light passes through the glass of
projection booth
NOTE:
● When light passes through the glass, the quantity of
light decreases. Make sure that the glass of the
projection booth is not more than one piece.
● Do not use glass if possible.
● When projecting light on an inclined glass surface,
adjust the glass angle as well as installation angle of
this unit accordingly to prevent impact on the image
due to diffuse reflection.
