complex objects. This does not mean that object usually belonging to complex objects can not exist
even as simple instances. One buoy tower can exist both as stand alone object and it can exist as a
part of one Navigational Aid, fixed or floating complex object. The decision of when one object will be
encoded in one or another way is influenced by many rules on paper charts. Sometimes, it is better
in one way, sometimes in another. Therefore, if can happen that one buoy on one scale level in one
chart belongs to a complex object, and on the more detailed level in another chart the same object with
the same coordinates can be a stand alone object. The default setting is Single.

If the complex object is composed by "BUOY, GENERIC", "BUOY, CARDINAL", "BUOY, SAFE
WATER", "BUOY, ISOLATED DANGER", "BUOY INSTALLATION", "BUOY, LATERAL", "BUOY,
SPECIAL PURPOSE", the symbol that appears on the screen is the complex object "BUOY".
If the complex object is composed by "TOWER", "LIGHT", "RADAR REFLECTOR", "FOG SIGNAL",
"RADAR TRASPONDER BEACON", "RADIO STATION_REFCO", "RADAR STATION", the displayed
symbol is the complex object "NAVIGATIONAL MARK FIXED".

Compute Correction
Corrects fixes from the positioning instrument. By placing the cursor on the ship's real position and
selecting this option, the error is calculated and internally memorized for appropriate correction, but
not applied.

Coordinates
Centers the map at the coordinates entered manually using the
ShuttlePoint knob.
'MENU' + "FIND" + 'ENTER' + "COORDINATES" + 'ENTER'
Coordinate System
Sets your preferred Coordinate System among ddd mm ss, ddd mm.mm, ddd mm.mmm, TD. The
default setting is ddd mm.mmm.

Correction
To compute fix error in automatic mode, place cursor on ship's real position and then follow the
procedure (compute correction). It is also possible to compute the fix error in manual mode (correction
offset). Once you computed the error, you can turn the fix correction On or Off.
Correction Offset
Manual correction of fix position.
'MENU' + "ADVANCED SETUP" + 'ENTER' + "FIX" + 'ENTER' + "CORRECTION OFFSET" + 'ENTER'
Course (Simulation)
Sets the desired value for heading in Simulation mode. The default setting is 000° M.
'MENU' + "ADVANCED SETUP" + 'ENTER' + "SIMULATION" + 'ENTER' + "COURSE" + 'ENTER'
Cross Track error = XTE
The distance from the ship's present position to the closest point on a line between the origin and
destinations Waypoints of the navigation leg being travelled.
CTS = Course To Steer
The optimum direction the boat should be steered in order to efficiently make headway back to the
courseline while also proceeding toward the destination Waypoint.
Cultural Features
Enables (On) or disables (Off) the displaying of the Cultural Features (any man-made topographic
feature as built-up area, buildings, roads, ...). The default setting is On.

Current
Non-periodical movement of sea-water, generally horizontal, due to many causes such as different
