Set Up Receiver for New Waypoints
Set up receiver to create first waypoint from
paper map coordinates (match datum and coordinate
system).
After creating first waypoint in GPS receiver
Change datum and coordinate system to match
second set of coordinates youll be given. Create
new waypoints from coordinates derived with this
datum and coordinate system.

waypoint using the Map page.
MENU
Option 1 Use Main Menu to access Points list.
NAV
Option 2 From any page, press NAV button once,

Option 1 Choose GOTO. The better choice, with
more navigation options.
Option 2 Choose Map. Navigating using only the
Map page. Simple, but not as useful.
13
Navigating to a Waypoint
Option 1 GOTO provides valuable navigation
information. Data fields can be set to show
bearing, distance and other information.
Electronic compass is linked to GOTO.
Option 2 Map shows destination waypoint.
Destination waypoint is identified by white
arrow. Coordinates, bearing and distance to
waypoint are shown at top of screen. Data fields
cannot be used. Electronic compass is linked to
GOTO.
14
Navigating to a Waypoint
Map page provides a graphical navigation display.
Data fields can be turned off to maximize map
size, or can be changed to provide other
information.
15
Using GOTO Compass to Navigate
Name of destination waypoint (available only with
GOTO)
Direction to GOTO waypoint
Indicates electronic compass is on
Compass can be used at any time, but only GOTO
can be used to provide automatic navigation to a
waypoint using the compass. Using compass
consumes more battery power.
16
Exercise
Instructor will provide you with coordinates to
enter into your GPS receiver. Be sure to set up
your receiver with the proper datum and
coordinate system before entering coordinates.
After creating new waypoints with the provided
coordinates, proceed with the navigation
exercise. Upon completing the exercise return to
the classroom.
