10. (A) The gray bands get darker on 2 areas in the middle (not the exact center),
(B) The gray bands get darker on 1 area at the center,
in these cases, find a face of the pin (11) on both sides in the same turn(s)
so that unevenness
of the gray bands could disappear.
<Example>
As which direction (clockwise or counter clockwise, in other words, the LED Head Unit to
frontward or backward) to turn the pin may vary by the case, try both directions
.
Compare the results to find the better direction.
Worse: try another direction. OK
Counter Clockwise
Move forward
Clockwise
Move backward
NOTE
(1) The actual “original front face” may vary by the case.
(2) It is not always applied that the same face of the left / right pins comes to front.
For example, the proper focus would be achieved if “+0.1mm” (light blue) comes to front
on the left pin and “+0.3mm” (red) does on the right pin at the same time.
