Initial Position Entry
The initial position field allows you to define a start­
ing point for simulated trips or name an initial position to
speed up the acquisition process if the unit has moved
more than 500 miles with the power off. When the unit
is in simulator mode, you may select a known waypoint
as your starting position, or define a distance and bearing
from a known waypoint to calculate your starting latitude
and longitude.
When the unit is in not in simulator mode, the bear­
ing and distance fields will not be available. Keep in mind
that while entering an initial position may speed up
acquisition, entering an incorrect initial position w'ill have
an adverse effect on the receiver’s ability to find the nec­
essary satellites to calculate an accurate position.
To enter an initial position reference:
1. Highlight the 'Ref field.
2. Enter the iden^ier of the reference position waypoint
and press'
