R70
OUT
Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay (RY2).
The signals holds "L" level during micro-
wave cooking and "H" level while not cook-
ing. In other cooking modes (variable cook-
ing) the signal turns to "H" level and "L"
level in repetition according to the power
level.
