• Head Up: The chart is displayed with the vessel's current heading upwards.
This is useful if you wish to compare the chart with a radar screen.
As the heading changes the chart will rotate, although some damping is
provided to stop it swinging too wildly. You can set the amount of damping
by adjusting the Head Up Response parameter in the system set up (see page
69).
When you first select Head Up Mode, or if you select Home Mode when in
Head Up Mode, the cursor is homed on the vessel and the chartplotter
display is in Relative Motion mode. In this mode, the chart moves to keep
the vessel in the centre of the display. When you move the cursor away from
the vessel, the display returns to normal True Motion, and the vessel moves
across the chart.
Note: When the chart rotates in Course Up or Head Up mode, it may not be
possible to display the chart text. In this case, markers are left at the text points
which you can interrogate using the cursor (see Chapter 2).
To select the orientation:
1. Press MENU to display the main menus.
2. Use the trackpad or the SCREEN soft key to highlight the ORIENTATION
option from the SCREEN menu, and press ENTER. The soft key labels
change, as follows:
3. Press the soft key corresponding to the chart orientation you require. The
new chart orientation is displayed.
4. Press the EXIT soft key, or CLEAR to clear the soft key labels.
The display reverts to the default soft keys display, with the new chart
orientation.
Setting Up Windows
A powerful feature of the chartplotter is the ability to define your own windows
so that, when you request a windowed display, precisely the data you require is
displayed alongside the chart. You can define up to four customized windows.
Six default windows are also provided.
The default windows are selected using the DISPLAY key options, as described
in Chapter 2. These options allow you to select the data set to be displayed in
either one or two windows, with a choice of window positions.
