Navigation Setup
The Navigation Setup
menu enables you to
change the coordinate
system, map datum,
north reference, map
orientation, and NAV
2 screen setup. It also
activates or deactivates
course projection.
Selecting Coordinate System
Position coordinates displayed on the NAV1 screen and
waypoint coordinates displayed on the waypoint screen can
be based on latitude/longitude, Universal Transverse Mercator
(UTM), Ordinance Survey of Great Britain (OSBG) or Lo-
ran TD’s. If latitude/longitude is selected, the position can
be displayed in Degrees, Minutes, Seconds or Degrees, Min-
utes and fractions of minutes to 2 or 3 digits of resolution,
(ddd mm.mm or ddd mm.mmm).
The important difference between Deg/Min/Sec
and Deg/Min/Fractions is that there are 60
seconds in one minute of latitude or longitude (the
seconds value will always be between 00 and 59),
whereas fractions of a minute are expressed in
decimal format (from .00 to .99, or .000 to .999).
Press the Aux softkey, use the CURSOR
KEY to highlight Navigation Setup, and
press ENTER. Use the CURSOR KEY to
highlight Coordinate System, and press
ENTER.
Use the CURSOR KEY to highlight desired coordinate
system and ENTER to set.
If TD’s is selected, the chain and pair
must be chosen.
The ASF value can be set to correct
the coordinates in case of map shift 0.0
to 9.9.
Turn Prime OFF if the coordinate position does not corre-
spond to the chart position. (Since two solutions are pos-
sible, mathematically, in certain rare cases the second cal-
culation is the more accurate of the two.) Press ESC to
exit.
