8.2.3 Permanent warnings for S57 charts
Permanent warnings help you keep the S57 charts up-to-date and these are shown at the top left corner on the
screen. Only up-to-date S57 charts can be legal replacement for paper charts. Permanent warnings appear if the
system detects a condition that may cause the use of charts that are not up-to-date.
Note: The system can assist in keeping RENC-received charts up-to-date. For charts that have been loaded from
sources other than an RENC, the system is unable to know the exact up-to-date situation.
For details, see section 8.11 "Chart Viewing Dates
and Seasonal Features of the Vector Chart".
You have loaded updates into your hard disk, but
these updates are not included in the SENC. The
name of the chart appears in orange in the chart
catalogue.
Perform SENC conversion for these charts. See
section 8.4.6 "How to use SENC convert window to
initiate SENC conversion " for the procedure.
For details, see section 8.6.9 "How to find up-to-date
status of an RENC Product List".
You have loaded an update that contained cancelled
information for a chart, and you have selected not to

Consider removing the chart. For information on
how to remove S57 charts, see section 8.5.4 "How to
remove S57 chart cells from the system".
