12.4 Touch screen calibration

The touch screen is calibrated at the factory and rarely needs modification. However, if actual touch

locations do not appear to correspond with responding objects on the display, field adjustment is

available. To access the field adjustable touch screen calibration dialog, press and hold both the SYS and

F1 key for longer than 2 seconds and a dialog similar to figure 9.2 should appear. Thereafter, use a

plastic tip stylus and follow the dialog instructions.

Note that special system keys may be locked out from user access. If the SYS-F1 combination does NOT

respond, verify that the system menu’s Set Fkeys sub-menu’s parameter SYS_Fn is enabled.
