Section 3 Operation
3.9.4.1.1 Control Setup
This screen allows the user to set the Date and time which will be used for reporting
and for the fault log.
It also allows for adjustment of the contrast of the GUI LCD display. The display
contrast will adjust dynamically as the number is changed to allow for room
lighting.
The last box here is the Screen Saver setting. It allows the user to select how long it
will take for the screen to blank out due to inactivity.
The only function button is the Touch Cal or Touchscreen Calibration. This should
not require routine adjustment.
3.9.4.1.2 Touch Screen Calibration
If the touch screen soft buttons on the GUI are working and seem to be accurate,
then this procedure is not required. If the soft buttons on the touch screen do not
seem to work or can only be activated by pressing outside the button graphic, then a
simple touch screen calibration will have to be done as follows:

Disable buttons at the same time and momentarily reset the main
controller. Keep the Enable and Disable buttons pressed until the
display is up and running. After the micro resets, the Main
Controller will prompt the operator to calibrate the touch screen.
