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.
