Permanent messages for S57 charts

Permanent messages help you keep the S57 charts up-to-date and these are shown at the top left corner on the
screen. Permanent messages appear if the system detects a condition which may cause a chart to be not up-to-date.
Note: The system can assist in keeping RENC-received charts up-to-date. For charts which have been loaded from
sources other than an RENC, the system is unable to know the exact up-to-date situation.
For further details see section 7.11 Chart Viewing
Dates and Seasonal Features of the Vector Chart.
