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 

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 

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

maximum vertical image offset, there is no horizontal lens shift.
