24、d re-do from the beginning. Note: As far as the Touch Panel Adjustment data is concerned, the data is finalized when the touch is let go. For this reason, the knack for adjustment is not to let go the touch after touching the center section of the +-mark. After making the touch, first confirm that t

25、he touch is at the dead center of the +-mark. (This means that, if the touch is not at the dead center of the +-mark, maintain the touch, and slide the stick to the dead center of the +-mark. ) Then, let the touch go quickly, vertically upward.

At first, use OSD key to adjust so that background is not seen on both sides of screen. Then, use the Screen Adjustment key so that the Monoscope is symmetric on right and

27、 left sides. 3-3. TV/VIDEO At first, use OSD key to adjust so that background is not seen on both sides of screen. Then, use the Screen Adjustment key so that the Monoscope is symmetric on right and left sides. 3-4. NAVI At first, use OSD key to adjust so that background is not seen on both sides of

28、 screen. Then, use the Screen Adjustment key so that the NAVI Menu screen is symmetric on right and left sides. After adjustment, press the Next key. If “Hposi OK” is dis- played, the adjustment is complete. Note: If the display does not come at the dead center when adjusting the horizontal display

29、start position (when adjust- ing one step left, the picture is to the left and, when adjust- ing one step to the right, the picture is to the right), press NEXT key with the position to the right and finalize the adjustment.
