SECTION 6
The NavTalk uses this basic information to mark
exact positions as waypoints, which help guide you
from one place to another. Average speed, sunrise and
sunset times (at your present position) also appear on
the Position Page (as default selections). Units of mea-
sure and the position readout are selectable from the
Main Menu, as outlined on page 98. ‘Trip Computer’
functions—such as average speed, max speed, trip
odometer and trip timer—can each be reset from the
Main Menu, as described on page 92.
The following options are available:
Average Position - averages position samples over
time. Averaging reduces the effects of selective availabili-
ty on position error and results in a more accurate posi-
tion reading.
To average position samples and save the
result as a waypoint:
1. Highlight ‘Average Position’ and press ENTER. The Average
Position Page will appear. Observe the ‘Estimated Accuracy’
and ‘Measurement Time’ fields.
2. When the ‘Estimated Accuracy’ and/or ‘Measurement Count’
figures reach the desired value(s), highlight ‘Save’ and
press ENTER. (To cancel the averaging function, highlight
‘Discard’ and press ENTER.)
3. The New Waypoint Page appears with a three-digit number
assigned as a name for the new waypoint. To save the way-
point with this name, highlight ‘Done’ and press ENTER.
Change Fields - allows you to choose the type of
data you want displayed in the six data fields.
The types are:
•Altitude •Speed
•Average (Avg) Speed •Sunrise (@ prsnt. pos.)
•Battery (Bat) Timer •Sunset (@ prsnt. pos.)

•DOP •Track
•EPE •Trip Odometer
•Last Call Time •Trip Timer
