Installation Manual
4.3.1 Screen Calibration
Use this procedure to calibrate the touch screen for more accurate display control. When performing this
calibration the user must be as accurate as possible. For best results a stylus is recommended. This
procedure can also be accomplished using the MPC and Lynx MAT. Refer to procedure in Calibration
and Test in the installation checkout section. Note: If the screen is severely out of calibration, this
procedure will not work and the screen calibration procedure in the Lynx MAT will need to be performed.
