After you suspect a line fault, which step is part of safe practice to restore communication?

• A. Stop using the suspected line and switch to a known-good line or replace faulty components.
• B. Immediately replace all wiring on the ship.
• C. Increase the transmitter power to overcome the fault.
• D. Clear the line by disconnecting all devices.

Answer: (A)

When you suspect a line fault, the safe practice is to stop using the suspected line and switch to a known-good line or replace the faulty components. This isolates the fault, preserving clear, reliable communication and preventing further damage or misoperation on the faulty circuit. Pushing transmitter power higher won’t fix the underlying issue and could cause additional problems or safety risks. Disconnecting all devices or replacing all wiring is excessive and disruptive, and doesn’t address the fault directly. The goal is to restore safe, dependable communication by using a verified good line or repairing the faulty part.
