<Caution>
(1) The power of the signal generator should be turned on before turning on the power of DC power
supply.
(2) The voltage of DC power supply, in standard of Module input voltage, should be preset as below.
(Vs : 190V, Va : 60V)
(3) The power of power supply must turned on by this sequence. Reverse direction When turning off.
* Module on : 5V Va Vs, * Module off : Va Vs 5V
(4) Signal generator should be selected with 1366 x 768(Fall in with 60X5A)mode.
