This symbol appears on all
three screens of the
position fix when the SQ
from one or more satellites
is 3 or less.
Old Data
The unit automatically updates its position every second. If a satellite
signal is lost, or a satellite sets or becomes obstructed, the unit
switches to
other satellites to update the fix. If other satellites are not
available, the
unit cannot update the position fix.
The hourglass symbol
appears on the position
display when the unit is
displaying a position fix
that is at least 10 seconds
old. The position displayed
is
not current, and should
not
be used for navigating.
ROUTE
The ROUTE key is used to enter a route consisting of 1 to 10 legs and
to
change route legs.
A route is established by setting a series of waypoints to correspond to
the
legs of the route.
A route can be followed in either the automatic or manual mode. The
route
mode is selected in SETUP. (See page 4-33.)
In either mode, when following a route, the navigation screen is
updated
every second, and the unit displays a "CLOSE" message
