which are not present on the original paper chart (from which the electronic chart derives). These

to provide more information useful for the navigation. VAD object can be any cartographic objects
and it can be distinguished from the official-chart-objects from the Quick Info. A dedicated icon
is shown on the Quick Info window to indicate that the object queried is a VAD. The same icon
is also shown on the Full Info page and in addition the extended text Value-Added Data is shown

Chart Lock (*) : Sets On/Off the Chart Lock option. When Chart Lock is On, the available zoom scales are only

into zoom scales not covered by cartographic data after the last available zoom scale covered by
cartographic data. The DSI window, if present, will show “NO CHART”, when an empty level is
entered in the location of map expansion mode.
NOTE* When an empty level is entered, the message “No cartographic coverage” is
shown on a window in a corner of the map display. The warning message is
always displayed as long as the current zoom has no data coverage.
