5. Green lens adjustment: Set the lens at the point where Blue just changes to Red. If the color aberration is irregular throughout the picture screen, adjust the lens to show Red color aberration (approximately 1~3 mm area) within a 3-block grid around the horizontal center-line. If the color aberration is irregular, adjust the lens as shown in the diagram below. (Accurate alignment of Green is important for overall color quality.)

6. Red lens adjustment Set the Red lens at the point where Orange becomes Crimson.

7. Blue lens adjustment Set the Blue lens at the point where Purple becomes Green.
