Adjusting the image height
The projector is equipped with 1 adjuster foot. This adjuster changes the image height. To
adjust the projector:
1. Screw the adjuster foot to adjust the image
height.
To retract the foot, screw the adjuster foot in a
reverse direction.
If the projector is not placed on a flat surface or
the screen and the projector are not

damage to your eyes.
• Be careful when you screw the adjuster foot as it is close to the exhaust vent where hot air
comes from.
