4 ¢ Adjust "yyyy" to 220 ✻
5 PLAY [b=xx yyyy/] point b

4 ¢ Adjust "yyyy" to 220 ✻
7 PLAY [C=xx yyyy/] point c
Check "yyyy" within 50
8 PLAY Display shows [aa bb cc(xx)] focus bias adjust
(aa= point a,bb=b,cc=c )
* Notes :
1. The relation between the C1 error and focus bias value
is shown in the figure below. Points "a" and "b" in the
figure are detected by the above adjustment. Focal
position "C" is automatically obtained from points "a"
and "b" by calculation.
2. The C1 error rate fluctuates. Therefore, perform the
adjustment according to the observed mean value.
