When observed on the Minimum Keyboard Display (MKD), the minimum carriage requirement for SOLAS vessels, for each aid to navigation the mariner will see an MMSI number (992351020), name, position, and bearing and distance from observer.

Trinity House notes that mariners using certain radar and electronic chart displays may see a symbol on the display and on interrogation, as a minimum, the above information will be available.

If displayed, the screen symbol for an AIS AtoN is a diamond shape. Currently there is a variance on information that will be displayed by different manufacturers on Electronic Chart and Radar equipment.

Paper charts will have an amendment applied with AIS, written in magenta, adjacent to the AtoN.
