Dynamic Nav-Aids
[MENU] + "Map Options" + [ENTER] + "Dynamic Nav-Aids" + [ENTER]
This function allows settings blinking lights on Nav-Aids. The blinking period and color of each
Nav-aid is read from the Nav-Aid attributes available on the data cartridge. When the ship is
inside the Nav-Aid nominal range, the light of the Nav-Aid will start blinking.
NOTE
When Dynamic Nav-Aids option is set to On, when the flashing light is Off, or when fix position
is out of the sector, the light color is displayed by using a faint light color.
Map Orientation
[MENU] + "Map Options" + [ENTER] + "Map Orientation" + [ENTER]
The possible choices are listed in the table below:
North Up The map is shown with North upwards.
Head Up The map is shown with the ship's current heading upwards. If Head Up is
selected, insert the Map Orientation Resolution angle in the range [5, 60]
degrees.
Track Up The map is shown with the currently selected course leg upwards. If
Track Up is selected, insert the Map Orientation Resolution angle in the
range [5, 60] degrees.
Mixing Levels
[MENU] + "Map Options" + [ENTER] + "Mixing Levels" + [ENTER]
When the map coverage at the current zoom level does not fill the entire screen, the chart
plotter draws the rest of the map expanding the cartographic information read from, at most, two
zoom levels above the current zoom level. For this reason the map is drawn three times: firstly
it draws the two levels before the current level and then the current level. The area covered by
the cartographic data read from the previous levels is identified by a dotted pattern. When the
cursor is moved on an area not covered by data of the current level the chart plotter zooms out
to the first level covered by cartographic data.
NOTE
The Mixing Levels function affects the speed of the redraw of the screen. If this function is not
used it may be disabled.

allowing to show the Safety Status Bar. In this case - when the Safety Status Bar is opened
via Warning alarm Icon - it is allowed to obtain information about each “active” Safety Status
box (the red ones): it is possible to select them by cursor movement left/right, and a list
of active alarms is shown underneath the selected box. By pressing [CLEAR], the Safety
Status Bar is removed from the screen.
