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

as your starting position, or define a distance and bearing

from a known waypoint to calculate your starting latitude

and longitude.

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
