What alarm sounds when a target enters a guard zone?

When a target moves into your defined safe distance around your vessel, you hear the guard zone alarm. This alert is specifically tied to the guard ring or guard zone you set in the radar/ARPA system, which marks a boundary around your own ship. Crossing into that boundary signals potential proximity risk, prompting you to take proactive action such as altering course or speed. This is distinct from a collision alarm, which forecasts a potential collision based on predicted tracks and relative motion, not just proximity to a fixed boundary. A weather alarm alerts to adverse weather conditions shown by the radar, and a target lost alarm occurs when the system can no longer maintain a track on a previously observed target.
