The zoom number in the chart-scale box changes with each
press of the
IN
or
OUT
key.
Distance scale bar
On the left-hand side of the
CHART
screen is a vertical ruler
with alternating red and blue sections. The primary purpose of
the ruler is to provide an approximate scale of distances on the
CHART
screen. On the
DISPLAY SETUP
screen, you can set
the distance units to statute miles (mi), nautical miles (nm), or
kilometers (km).
DGPS indicator
In the upper left-hand corner of the
CHART
screen is the word
DGPS
, which indicates whether the system is receiving DGPS
corrections to its GPS signals. If corrections aren’t being
received, the
DGPS
indicator won’t appear on the screen.
Introducing the
chart screen’s menu
keys
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:
•
GO TO
provides several options to select and navigate to
new position coordinates. For details, see “Navigating to a
point” starting on page 1-24.
•
NEW CHART
lets you select a different chart for your
vessel’s location from the chart database, or display a
basic plotter grid. For details, see “Selecting new charts”
starting on page 4-8. Each time you briefly press
NEW
CHART
, the 961/962 cycles automatically through all
appropriate charts. When you press and hold the key,
more chart-selection options are displayed.
•
OVERLAY
provides the option to superimpose graphic
displays of tide data, currents, and a small echo sounder
picture (if the 490 is installed) onto the
CHART
screen. For
more information about overlaying graphic displays, see
“Alarms, TideTrack, Currents, and Echo Sounding” starting
on page 12-1.
Differential GPS (DGPS) is a
technique for correcting basic
GPS position data by
receiving additional radio
signals to increase its
accuracy.
