"Titanic"'s wireless operators received a warning from the SS "Californian". The operators, who were behind in sending messages due to a broken radio system the day previous, told "Californian" to shut up and keep out. "Titanic" was working to the Cape Race radio station, nearly 400 miles away. As such, "Titanic" had to have their headphones turned up to max to hear them. When "Californian" buzzed in, the noise was so loud it nearly deafened "Titanic"'s operators. "Californian" shut down their radio system for the night.
