Optical lens focusing
The optical focusing procedure is performed separately for each lens. The appropriate CRT will be switched on as the user proceeds through the optical focusing adjustment se- quence.
Each lens has two focus adjustment points, one at the rear of the lens and one at the front. The center of the projected image is focused by loos- ening the wing nut at the rear end of the lens and rotating the lens barrel until the center of the image is clearly focused. The corners of the pro- jected image are focused by loosen- ing the wing nut at the front end of the lens and rotating the lens barrel until the corners of the image are clearly focused. Repetition of these adjustments may be necessary to optimize optical focusing.
