4.3.1 Screen Calibration
Use this procedure to calibrate the panel mount Lynx NGT-9000 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 MPC (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 MPC (MAT) will
need to be performed.
1. Apply power to the unit using applicable essential or emergency electrical buses.
Initialization and self-tests begin.
2. After the splash screen is shown (i.e. L3 Logo) and begins to dim, press and hold in the lower left
corner (see red target below) of the display (continue holding when the status and version screens are
showing) until the Activate Maintenance Mode window is shown on the right screen. See Figure 4-1.

Timeout message is shown. The unit returns to the main screen.
7. If normal operation is desired cycle power to the unit or tap the Reboot text on the main screen
followed by tapping the Main App > text to perform a warm startup.
8. When in normal operation check that the touch screen accuracy has improved. If the accuracy has
not improved, try the calibration procedure again. If the issue continues contact ACSS Field Service
for help in resolving the issue prior to removing the unit for repair.
