Adjusting the 
Projector Height or 
Projection Angle
When the CL-420 is installed upright, you can adjust the projector height or projection 
angle by turning the four adjustable feet on the bottom of the projector; see 
Figure 4-1. 
This is useful for correcting the angle of projection when the projector is placed on an 
uneven surface or when the screen is at an angle. You can tilt the projector up to five (5) 
degrees up or down by adjusting the feet.
The feet are connected to threaded bolts; turn them clockwise to raise the projector or 
counterclockwise to lower it.
