Many features of the GPS III Pilot are menu driven. Each of the main pages has an
options menu, allowing you to custom tailor the corresponding page to your prefer-
ences and/or select special features which specifically relate to that page.
To display the Position Page Options, press MENU (with the Position
Page displayed).
The following options are available:
Average Position— allows you to average position samples over time and save
the averaged result as a waypoint. Averaging reduces the effects of selective availabili-
ty on position error and results in a more accurate position 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 Time’ figures reach the desired
value(s), highlight ‘Save’ and press ENTER. (To cancel the averaging function, highlight
‘Discard’ and press ENTER.)
3. The Waypoint Definition Page appears with a three-digit number assigned as a name
for the new waypoint. To save the waypoint with this name, highlight ‘Done’ and
press ENTER. Or,
4. To change the waypoint name, highlight the waypoint name field and press ENTER.
Use the rocker keypad to enter a new name for this waypoint and press ENTER when
finished. Highlight ‘Done’ and press ENTER to save the waypoint.
The Position Page Options
allow you to average position
samples and save the result as
a waypoint, change data fields
or restore factory defaults.

‘Measurement Time’ figures.
