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 a

t 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 so

urce 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 dis

tance 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 horizontal

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 position.

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 keystone to

re-position the image.

• The vertical image offset range is 105%

~130% for the SP8602 (default is

105%). The default horizontal image offset is +/-15%, however at maximum

vertical image offset, there is no horizontal lens shift.
