How to Find the Chart Type

The electronic chart system can display more than one S57 chart cell at a time. This
feature is called multi-cell display. If one S57 chart cell does not cover the whole dis-
play, the system opens more S57 chart cells for display, if appropriate cells for the dis-
played area are available. The Own ship functions box shows information about S57
chart cells displayed on the electronic chart display area. When automatic TM reset is
active, the information is displayed with reference to your ship's position. If TM reset
is OFF, the information is displayed with reference to current cursor position.

How to Update Charts Manually

Manual update may include deleting an already existing object, modifying a position
or other characteristics of an already existing object or inserting of a new object. In this
system, manual updates are stored in a common database.
Mariners cannot permanently remove any of the official objects from the chart display.
If a mariner needs to make obsolete any of the official objects he deletes them. Then,
in practice, the deleted features are still visible, but they are displayed a certain way
to indicate a deleted object.
However, a mariner can remove objects that he has inserted himself.
Note that the manual updates have no automatic connection to any automatic update
received later for charts. If a manual update itself became obsolete, because the offi-
cial chart has been updated to include the update defined as a manual update, the
mariner must himself delete the obsolete manual update in question.
The system records complete usage of manual updates. All deletions, modifications
and insertions are recorded and time stamped. If the mariner wishes to see what kind
of manual updates he had in the past, for example, two weeks ago, he uses Update
History to specify the relevant date range. For information on how to set Display date
and Approved until dates on S57 charts, see section 9.3.3.
Note 1: If the equipment automatically restarts when manually updating an ENC chart,
try the manual update again after the equipment finishes restarting. If you still cannot
do the manual update, reset the power then try again.
