ADJ 9.13 UI Display Calibration

Purpose
Adjust the display by making the buttons on the display correspond to the Touch Panel, so that
users can correctly select the content indicated on the display.
Perform this adjustment when UI PWB or the Control Panel are replaced.
Adjustment
NOTE: Use the stylus installed under the UI Control Panel for the adjustment. A tapered sub-
stitute can be replaced if the pen has been lost. In this case, care should be taken not to
scratch the UI surface.

lines with the stylus. A message is displayed on the screen after each touch.
After pressing down all the buttons, the machine will calculate the deviation and the cor-
rection value on the coordinates. This automatic calculation takes about 0.1 second.

6. Apply the stylus to each of the four line intersections. A black square should appear at the
point of contact, and a beep should sound.
• If four beeps are heard, adjustment is OK.
