To adjust the vertical
keystone of the projected
image
Loosen or tighten the lower screws on the projector mounting plate, turning each
screw equally a quarter or half turn at a time.
• Turn the adjustment screws clockwise to push the projector up, increase the
image width at the bottom and move the bottom of the image down.
• Turn the adjustment screws counterclockwise to push the projector down,
decrease the image width at the bottom and move the bottom of the image
up.
NOTE
The top of the image moves very little from its position.
To adjust the horizontal
keystone of the projected
image
Turn the projector to the left or right to adjust the image.
TIP
Move the focus lever until it is almost in the locked position – the friction will
help to maintain control when you’re moving the projector to the desired
position.
• Rotate the projector to the right to increase the right image size, decrease the
left image size and move the entire image to the right.
• Rotate the projector to the left to decrease right image size, increase the left
image size and move the entire image to the left.
