chart screen's menu

Page 1-20
The CHART screen is controlled by six menu keys that are
located in a vertical row to the right of the display screen. Each
of these keys controls a function to its left:
keys
•
GO TO provides several options to select and navigate to
new position coordinates.
•
NEW CHART lets you select a different chart for your ves-
sel's location from the 961's chart database, or display a
basic plotter grid. For details about the grid, see "Selecting
new charts" starting on page 4-8. Each time you briefly
press NEW CHART, the 961 cycles automatically through
all appropriate charts; when you press and hold the key,
the 961 displays more chart-selection options.
•
OVERLAY provides the option to superimpose graphic
displays of tide data and currents on the CHART screen.
•
CLEAR—when pressed briefly—clears the CHART screen
of menu keys (press any menu key to restore them); press
and hold CLEAR to clear menu keys and everything else
on the CHART screen, except for your vessel and the
range rings. The clearing action reduces on-screen clutter
so you can see more of the chart.
•
INFO (two identical keys) displays at the bottom of the
CHART screen two rectangular INFO BARS, which show
SOG and COG, numerical position coordinates, the active
waypoint (if any), and details about the chart in use. Note
that the 961 displays the second INFO key only after
you've pressed the one INFO key at the bottom of the
screen.
For more information about the CHART screen's menu keys,
see "Chart-view menu keys" starting on page 3-6.
You can display position coordinates on the CHART screen as:
•
lat/lon coordinates from the GPS receiver
•
phantom loran TDs that the 961 calculates from its GPS
coordinates (for when you'd like to see your position
mathematically converted to and displayed in loran TDs)
