area to be covered by ENC or a description of the routes you would like to be covered by ENC.

charts are purchased and the permits sent on board.

The permits are delivered as 2 files:
• If the permit was received on a memory stick, plug in the memory stick and select the
directory containing permits files.
• If the permit was received by e-mail browse the hard disk folder, open the permit file.
A message window gives information about the status of the installed permits and about
eventual errors.
PERMITS FROM SEVERAL PROVIDERS
If ENC cells are delivered by two different providers (Primar and UKHO for example) two
permit files are received on board. It is required to run two times the installation procedure
with the two different permit files.
NEW PERMITS
When additional permits for new charts have been ordered, a new permits file is sent on
board. This file contains the complete list of permits purchased by the user and must be
installed as described above. The new permits are added to the old ones.
