2.5 Chart Display Control Functions

Moving Around the Chart

You will normally operate the chartplotter with the chart showing your vessel's
current location. The default orientation is North-Up, and 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 waypoints in
another area. Alternatively, you can home the cursor onto the vessel using FIND
SHIP; this function can also be used on a combined display to sychronise the
radar and chart windows as described in Using FIND SHIP.
There are four 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. This method is useful if the area you wish to see is only just off
the screen.
• Use the context-sensitive cursor to change the chart centre.
• Automatically re-centre the vessel using the FIND SHIP soft key.
• Change the chart scale to zoom out and in to a new area centred on the cursor
position. This method is useful if the area you wish to see is a long distance
away.

Changing the Chart Centre

You can move the area of the chart displayed on the screen using the context-
sensitive cursor. This allows you to centre your vessel in the middle of the
screen, or to move the chart so that your vessel is displayed off-centre anywhere
on the screen.
➤ To centre the chart:
1. Use the trackpad to move the cursor to the vessel's position. The cursor text
POS is displayed.
2. Press CLEAR. The chart is moved so that your vessel's position is in the
centre of the screen.
➤ To move your vessel's position off-centre:
1. Move the cursor over your vessel's position until the letters POS are
displayed.
2. Press ENTER to take control of the chart position. The letters POS are now in
inverse video, and the cursor symbol has changed to a four-way arrow. This
indicates that the cursor can be used to move the chart in any direction.
