The alarm circle can help you avoid reefs, rocks, or restricted waters. You can add a maximum of 10 waypoints or on-screen map items to proximity alarms with a maximum alarm radius of 99.99 nautical or statute miles or kilometers. If a proximity alarm circle overlaps with an existing alarm circle, a "Proximity Overlaps Another Proximity Waypoint" message appears. Because the unit only alerts for one of the overlap points, use caution when navigating in these areas. If your boat enters an alarm circle overlap, you are only alerted to the closest proximity waypoint. GPSMAP 392/398/492/498 Owner's Manual 49
