-Adjust sequence

■Press the PIP key of the ADJ remote controller. (This PIP key is hot key to enter the VCOM adjusting mode)

(Or After enter Service Mode by pushing “ADJ” key, then Enter V-Com Adjust mode by pushing “►” key at “12. V-Com”)

■As pushing the right or the left button on the remote controller, And find the V-COM value Which is no or minimized the Flicker. (If there is no flicker at default value, Press the exit key and finish the VCOM adjustment.)

■Push the OK key to store value. Then the message “Saving OK” is pop.

■Press the exit key to finish VCOM adjustment.

4.6. Outgoing condition Configuration

■When pressing IN-STOP key by SVC remocon, Red LED are blinked alternatively. And then automatically turn off. (Must not AC power OFF during blinking)

4.7. Hi-pot Test

Confirm whether is normal or not when between power board's ac block and GND is impacted on 1.5 kV(dc) or 2.2 kV(dc) for one second
