The first display contains the current geographical coordinates in WGS-84 format
(a geographical coordinate system) and an estimate of the accuracy of the
location. The correct coordinates are shown only if the GPS receiver receives the
needed positioning information from the GPS satellites.
The second display contains the approximate altitude from the mean sea level. If
the device is moving, the approximate speed and the approximate direction of the
movement in degrees from true north are also shown.
The third display contains the approximate time of the measurement in Universal
Time (UTC) format and the number of satellites the radio is connected to
(maximum 12).
The text on top of the display informs you of the status of the GPS reveiver. If No
GPS fix is displayed, the GPS receiver is calculating its location or not receiving
information from the satellites, and the correct coordinates cannot be displayed.
The coordinates of the previous calculated position remain on the display until
new position information is received from the satellites.
If 2-D positioning is displayed, the coordinates are displayed, but the receiver
cannot calculate the altitude, because it is only receiving information from three
satellites. If 3-D positioning is displayed, the receiver is receiving information
from a mimimun of four satellites, and the coordinates and the altitude can be
calculated.
If you want to save the displayed position information as a waypoint (landmark),
select Save. Enter a name, and if desired, a short comment for the waypoint.
