Positioning the projector
To determine where to position the projector, consider the size and shape of
your screen, the location of your power outlets, and the distance between the
projector and the rest of your equipment. Here are some general guidelines:
•
Position the projector on a flat surface at a right angle to the screen. The
projector must be at least 4.9' (1.5m) from the projection screen.
•
Position the projector within 10' (3m) of your power source and within
6' (1.8m) of your video device (unless you purchase extension cables).
To ensure adequate cable access, do not place the projector within 6"
(.15m) of a wall or other object.
•
Position the projector to the desired distance from the screen. The
distance from the lens of the projector to the screen, the zoom setting,
and the video format determine the size of the projected image.
•
If the image is square but not centered on the screen or viewing area,
adjust it by using the lens shift dials. Use the Horizontal dial to shift the
lens left or right. Use the Vertical dial to shift the lens up or down.
NOTE: As the lens is shifted away from the lens centerline, the horizon-
tal shift range is reduced. To adjust lens shift efficiently we suggest you
follow these steps:
1
Use vertical lens shift to move the image closer to the lens centerline
than the final vertical position.
2
Use horizontal lens shift to determine the center horizontal position,
then move image to the center horizontal position.
3
Use vertical lens shift to move the image away from the lens centerline
to the final vertical position.
4
Use horizontal lens shift to move the image to the final horizontal posi-
tion.
5
If lens shift is unable to move the image far enough, move the projector
(preferable) or tilt the projector and then use vertical and horizontal key-
stone to re-position the image.
•
The vertical image offset range is 105%~130% for the IN5302 and
105%~125% for the IN5304 (default for both is 105%). The default
horizontal image offset is +/-15%, however at maximum vertical image
offset, there is no horizontal lens shift.
