How to know up-to-date status of a chart from a RENC
To keep Charts up-to-date you have to check situation in a RENC about at weekly basis. The ECDIS compares used
charts to Product List of RENC. If a Permanent Warning appears to Chart display of ECDIS, it is an indication
that at least one of used charts is not up-to-date compared to the Product List, see below:
The information of available charts and their up-to-date status is available both in Catalogue and in Date Dependent
window.
The easiest method to check up-to-date status is to view Catalogue and check that all required charts are
indicated as green. Charts which are not up-to-date are indicated as orange. See more "How to view the
Coverage of the RENC service" on page 98.
You can also use Date Dependent window on demand when you have doubt that some charts are not up-to-date or
you have the Permanent Warning shown above.
