ADJUSTMENT

● Video unit (X35-4250-00)

• Start a set in test mode at the time of video board adjustment.

•How to enter to test mode : Pushing operation of 2 keys right (clock)-and-left (image adj.) both ends side and a touch panel. And supply to power is ON.

• After starting : perform substrate adjustment for a video board by a design mode → VIDEO ADJ key with reference to the following item.

• Adjust a picture position by After starting : (AUX) Manufacture mode → POSI (NAVI)

• VIDEO ADJ mode : it is the rectangle color frog of middle at the time of adjustment item selection. It is considered as an adjustment end by choosing a rectangle again after adjustment.

No.
