You operate the radar and chart systems using a variety of controls:
• A trackpad providing up, down, left, right and diagonal control of an on-
screen cursor.
• Eleven dedicated (labeled) control keys.
• Four soft keys with labels displayed on the screen.
• Pop-up menus, displayed on-screen, from which you select options.
• Database lists, displayed on-screen, which enable you to edit items.
Note: The cursor is the cross-hair symbol (+) visible on the display. You move
the cursor using the trackpad and use it to select a position or item on the chart.
The control keys are shown in Figure 1-4. They are back-lit for night-time use.
When you use a control, a help message is displayed at the top of the screen
(unless you switch help off as described in Chapter 7). The following
paragraphs describe the controls and on-screen facilities.
