3.1 LCD Graphical User Interface
This interface is a 160 x 160 pixel touch screen with interactive hot spots that call forth more screens. The
best tool for navigating these pages is a stylus (a small pen-shaped instrument). Make selections by tap-
ping the stylus on the screen.
Auto-Logout Timeout
After 20 minutes of inactivity (no user input), the CXC automatically logs off the user. The CXC discards
any unsaved changes made by the user while logged in the system and returns to Normal Operation
mode. The access level is reset to the default user access and the screen continues to display live data.
Backlight Timeout
After one minute of inactivity (no user input), the CXC automatically turns off the LCD backlight.
3.2 Home Screen (Default Operating Screen)

monitors all input channels. See Chapter 4 for operating procedures with the LCD interface.
