Converting depth values into the units
set
Press GOTO to display the menu,
select SETUP, DEPTH UNITS and
then set the unit desired in

GEONAV will convert all the
depth values in the unit selected,
making them appear like those re-
ported in the official nautical
charts (see the figure).
Displaying abbreviated navaid characteristics
Position the manual cursor on the navaid
symbol. A window will show the abbrevi-
ated characteristics relative to the navaid

Displaying object attributes
Move the manual cursor on top
of an object on the chart, then
press the joystick. A window will
show the description of all the
objects present on the chart at
the cursor's position. Select one
object from this window and
press the joystick to show all of
the object attributes.
The objects that can be queried
include depth contours, depth
areas, point objects (lights,
navaids, landmarks, etc.), land
areas, spot soundings, coast-
lines, rocks, wrecks and, in gen-
eral, any symbol present on the
chart.
By querying the lights and navaids, the X-plain™ function
will give the description of the object in natural language,
thus avoiding the use of abbreviations and symbols hard to
understand.
Chart presentation mode
The symbols used to represent the objects on the chart (buoys,
lights, landmarks, etc.), as well as chart colors, can be se-
lected between paper-chart International or US styles.
Press GOTO to display the menu, select SETUP, then select
PRESENTATION (INTER. or US).
