2.6 Navigation Keys
The navigation keys on the front panel—F1 through F4 and Help—are used to access the LCD to view
the current status and other information about the NX.
Navigation key icons on the LCD appear above each key to indicate its operation (see Table 3). The
keys are “soft keys” that can change functions according to the icon.
•Use F1 either to move to a different portion of the LCD (shift icon) or to escape to a previous view
(ESC icon).
•Use F2 and F3 as cursor keys to move left and right or up and down, depending on the icons dis-
played above the keys.
•Use F4 as an Enter key to confirm a choice.
•Use HELP to access help information on the LCD.
