What does blinking red indicate?

• A. Just begun adequate signal
• B. Excellent signal
• C. No signal
• D. Trying to scan but no signal

Answer: (D)

Blinking red shows the unit is actively searching for a signal but hasn’t locked onto one yet. That scanning-without-a-lock status is exactly what “trying to scan but no signal” describes. If a solid signal were present or strong, you’d expect a different indicator pattern (a steady or different color), and simply having no signal wouldn’t typically be shown as a blinking red while actively scanning.
