A filled circle (left justified) in a UFCP data display window indicates the window

• A. Has a press and hold function
• B. Is inactive for data entry
• C. Is active for data entry
• D. Has toggle capability for two or more options

Answer: (A)

Understanding how indicators in a UFCP data display convey how to interact with a window. A filled circle positioned at the left side signals a press-and-hold requirement to access or modify that window. This cue makes it clear that the action isn’t completed with a quick tap; you must maintain pressure to engage it, which helps prevent accidental changes. The left-justified placement links the cue directly to that specific window, reinforcing the intended interaction. Other interaction cues would look different: inactivity is shown by absence or dimming, immediate data-entry readiness by a highlighted or active field, and toggling between options by a control that presents multiple states rather than a single dot. So the filled, left-aligned circle best matches the idea of a press-and-hold function.
