2.5 Controlling the Chart

You control the chart display using the cursor and control keys. You start all
operations with the initial soft keys displayed (this is referred to as the initial
screen in the following sections).
When you have completed an action using the soft key sub-sets, to return to the
initial screen, press CLEAR; you may need to press CLEAR several times to
back-track through the sub-set hierarchy.
Note: If you have set up your system so that the initial soft keys are not
displayed all the time, press any soft key to display the labels.
Although you can use your chartplotter with the whole screen devoted to the
chart, you can also display navigation data in one or two windows, with the
chart displayed in the rest of the screen. Navigation data windows are controlled
using the DISPLAY key.
This section describes how to:
• Move around the chart by panning the display, changing the chart scale and
changing the chart centre.
• Display navigation data.
Note: The orientation of your chart (North Up, Course Up or Head Up)
depends on your choice when you set up the chartplotter, as described in
Chapter 6.
The chart controls are summarised in the illustration on page 9.

Moving the Chart

You will normally operate the chartplotter with the chart showing your vessel's
current location. In the default North-Up orientation, the display is in True
Motion mode, in which the vessel moves across the screen. You will need to
move the chart if your vessel moves out of the area currently displayed, or if you
wish to examine or place marks/waypoints in another area.
There are three ways in which you can move the chart:
• Use the trackpad to move the cursor to the edge of the chart. The chart will
pan across (see Section 1.3). This method is useful if the area you wish to see
is only just off the screen.
• Use the RANGE key to zoom out to a small scale chart, move the cursor to the
centre of the required area, then zoom in on the new area . This method is
useful if the area you wish to see is a long way away.
• Use the CENTER soft key to center the chart on one of a choice of positions:
the vessel's position, the cursor position or a specified position .
• Automatically re-center the chart using the HOME option.
