Hint for the lens focus adjustment
The letter “H” is made up of dots. Adjust the focus so that dots of the letter
“H” can be clearly seen as illustrated below.
Placing a white paper over the front of the screen will make it easier to see
the dots.
Proceed to the adjustment for flapping of the green lens.
