Introducing the function keys

Page 1-16
Five keys located on the lower left part of the control head
instantly select the most common functions. Each successive
press of a function key selects additional display screens
belonging to that function. There are several screens under
each function key (except for the TRIP key). For each function,
the system remembers the last-viewed screen, returning there
when you later select the function. The one exception is the
STAR function key, which always brings you directly to the
ECHO SOUNDER screen if the 490 has been installed.

The function keys are briefly described below.
CHART displays two independent CHART screens (views
•
A and B) showing your position on the chart, information
about the chart-in-use, all the data you need to navigate,
tides (using Northstar's exclusive TideTrack™ feature),
and currents overlay. You can create and store new
waypoints, avoidance points, and routes at these screens,
and view existing waypoints, avoidance points, and
routes. You can also view the echo sounder's picture on
part of the CHART screen.
STEER displays two screens helping you to steer precisely
•
along the desired track to your upcoming, or active,
waypoint. This screen includes a display of your
speed-over-ground (SOG), course-over-ground (COG),
name of the active waypoint, distance, estimated time of
arrival (ETA) and estimated time enroute (ETE) to that
waypoint, bearing, numerical and graphical cross-track
error (XTE), and mapped waypoints.
