Note:
The convergence circuit is a circuit to eliminate screen distor-
tion 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.
Before proceeding to the adjustment for each screen, always
perform the adjustments for vertical size (HIT) and horizontal
size (WID) with the main deflection data changed.
The menu order is 1~6 .... when the input signl is PAL. (In this

The menu order is 7 .... when the input signal is NTSC. (In this
