2-6 Raychart 320 Chartplotter
2.4 Chart Display Control Functions
You will normally operate the Chartplotter with the display showing your
vessel’s current location.
The range of pages is listed in Selecting the Display Mode on page 2-4
and illustrated in Figure 2-6. The complete range of pages is described
fully in Data Display Pages on page 3-7.
Moving Around the Chart Screen
When using the chartplotter screen, the default orientation is North-Up,
where the vessel moves across the screen. You will need to pan the
display if your vessel moves out of the current area, or if you wish to
examine or place waypoints in another area. Alternatively, you can home
the cursor onto the vessel using
FIND SHIP.
There are four ways in which you can move around the display:
• Use the trackpad to pan the display.
• Automatically home (re-center) the vessel using the
FIND SHIP soft
key.
• Use the context-sensitive cursor to change the chart center.
• Change the display scale to zoom out and in to a new area centered on
the cursor position. This method is useful if the area you wish to see is
a long distance away.
Panning the Display
Panning the display is useful if the area you wish to see is only just off the
screen.
➤ Use the trackpad to move the cursor to the edge of the display; the display
will pan across.
Using FIND SHIP
FIND SHIP is used to center the vessel on the screen, even if it is currently
off screen:
➤ Press the FIND SHIP soft key; the following actions occur:
• The display is re-drawn with the vessel’s position in the center.
• The cursor is homed (locked) to the vessel’s position and moves with
it.
• When the vessel moves near the edge of the screen, the display is
redrawn to place the vessel and cursor at the center.
• Whilst homed, the status bar indicates vessel position, speed and
course over ground.
