Which status is conveyed by a blinking yellow indicator?

• A. Indicating a scan error
• B. Just begun adequate signal
• C. Excellent signal
• D. Scan complete

Answer: (B)

Blinking yellow shows a transitional status during the initial engagement of the system. It means the acquisition process has started and the signal is adequate, but not yet at full strength or stability. It’s not an error, and it’s not finished yet, which is why this pattern best matches the idea of an indicator that has “just begun” and is still in the early stage of signal acquisition.

If the indicator were indicating a scan error, you’d expect a fault signal such as a red or sustained fault pattern rather than a blinking caution signal. An excellent signal would be a solid, steady indicator (typically green) showing full, stable strength. Scan complete would usually appear as a different one-time change or steady state indicating completion, not a blinking transitional cue.
