When a customer calls, what will you hear and what light is illuminated?

• A. A double chime and blue light illuminated on the master call panel
• B. A single chime over the cabin PA system and amber light illuminated on the master call panel
• C. A single chime over the cabin PA system and blue light illuminated on the master call panel
• D. A continuous chime and no lights illuminated on the master call panel

Answer: (C)

When a passenger calls, the system produces a single chime over the cabin PA and the blue light on the master call panel illuminates. The single chime alerts the crew to the call, and the blue indicator shows that the call originated from a passenger seat, helping you locate and respond quickly. The light typically stays on until the call is acknowledged or cleared. The other scenarios—double or continuous chimes, amber lights, or no lights—do not match the standard passenger call alert on the 737-700, which is why the single chime with a blue light is the correct behavior.
