Initial Position.
By entering an initial position you are informing the receiver
of approximately where it is; you should know this position within 300 miles
(approximately 480 km). If you do not know your coordinates, refer to the
City Reference Chart to key in the coordinates of the nearest City.
To enter an initial position:
1.
Press
AUX/SETUP,
and the
LEFT ARROW.
"INITIALIZE" is
highlighted. Press
ENTER.
2.
The initial position is displayed as zero position coordinates in
Lat/Lon and degrees/minutes.
3.
Press the
UP/DOWN ARROWS
to enter the first digit of your
latitude. (Data entry is described in more detail in
Tutorial.)
Press the
RIGHT ARROW
to move the cursor to the next digit
and repeat. If necessary, change the displayed hemisphere (N or
S) by moving the cursor to the hemisphere and pressing the
UP/
DOWN ARROW.
Press
ENTER
to save the entry.
4.
Enter your longitude in the same manner as the latitude. Press
ENTER
to save the entry.
5.
Key in your elevation (mean sea level) in feet. If necessary,
toggle the ± elevation prefix with the
UP/DOWN ARROW.
Press

The unit of measure for elevation can be changed later in
SETUP. If you know what your altitude is in feet, enter it now;
the receiver will automatically make all necessary conversions if
you later change the unit of measure to meters.
