625P, NTSC 525P, 1080i 50 Hz 4:3 or 16:9, 1080i 60 Hz 4:3 or
16:9. To synchronize correction wave to each frequency, re-
ceive the suitable signal.
Note: The convergence circuit is a circuit to eliminate screen
distortion and can not make a drastic correction such
as to correct entire screen size. An excessive correction
may actuate the protection circuit. So a care will be
necessary.

QH100 is eliminated with power OFF, the RAM is set by soft
command of micro-processor QA01 at each time of power ON.
The adjusted data which is obtained from screen-watching is
once stored in RAM inside QH001. The whole data in RAM
which is corrected on each adjusting point and is changed, is
