Display Functions Switches

The six Display Functions switches, labeled F0 through F5, are strategically located on the right side of the Cathode Ray Tube (CRT) screen (see Figure 2-3). These switches are referred to as soft keys because their functions are dynamically assigned by the software associated with the specific CRT display (refer to Chapter 3 for more details). Each switch's function is clearly displayed on the right side of the CRT screen, right next to the respective Display Functions switch.

Here is a detailed view of the Display Functions switches and their roles, particularly within the Alarm Display mode:

  • NEXT PAGE (F0): Pressing this switch will display the next page of the Alarm List, allowing users to navigate through multiple pages of alarm information.
  • DIAGNOSTIC ALARM (F1): If diagnostic alarms are present, pressing this switch will bring up a list of Diagnostic Alarm messages, providing detailed information on any system issues.
  • (blank) (F2): This switch is currently unassigned and does not perform any function in the Alarm Display mode.
  • ALARM LOCKOUT (F3): This switch locks the alarm in its current position on the display. This is useful for focusing on a particular alarm without it moving or being overwritten by other alarms.
  • ALARM UNLOCK (F4): Pressing this switch will unlock the alarm, allowing it to be repositioned or replaced by other alarm messages as necessary.
  • ALARM ACKNOWLEDGE (F5): This switch acknowledges all flashing alarms. Pressing it will clear the visual indication of the alarms, indicating that they have been seen and addressed.
