To adjust the calibration of the touch screen key alignment, press the ‘TOUCH SCREEN’ key. The 6400
controller will take the user through a series of prompts to execute calibration. Touch the center of each target
for best results. When calibration is complete press the ‘OK’ key and then press the ‘ENTER’ key to save the
settings.
The Touch Screen can be set up to have the backlight on continuously by placing dipswitch 6 in the ‘OFF’
position (Refer to Figure 28). The unit must be reset to acknowledge any changes in the dipswitch settings.
Note that having the backlight on continuously will shorten the life expectancy of the Touch Screen Display.
