Value Added Data : Turns the Value Added Data On or Off. The Value Added Data (VAD) is a collection of additional
cartographic objects which are not present on the original paper chart (from which the electronic
chart derives). These objects have been obtained from other sources and then merged to the
electronic charts in order 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 on the details of the VAD object. See the figure below:

Chart Lock (*) : Turns the chart function On/Off. When Chart Lock is On, the available zoom scales are only the
ones containing cartographic data. Instead when Chart Lock is Off, it is possible to zoom down
into zoom scales not covered by cartographic data after the last available zoom scale covered by
cartographic data. The DSI (Data Safety Indicator) window, if present, will show “NO CHART”,
when an empty level is entered in the location of chart expansion mode.
Mixing Levels : When the chart coverage at the current chart scale does not fill the entire display, the GPS Chart
Plotter draws the rest of the chart using charts from above and below the current scale. When this
function is turned on you will notice the display may redraw 2 to 3 times to show all the details.
NOTE(*)
When an empty level is entered, the message “No cartographic coverage” is shown on a window
in a corner of the chart display. The warning message is always displayed as long as the current
zoom has no data coverage.

from “Underwater Object Depth Value” option).
