Operator Manual
Figure: 1−6 Menu Bar and pull−down menu
Ellipsis (...) − Before it carries out the command, the ECDIS will prompt
you for more information by displaying a dialog box.
Check mark (√) − The command is a "toggle" command, one that is either
on or off. The check mark indicates that the command is on or active.
Selecting the command again turns it off and the check mark disappears.
Accelerator Keystroke(s) − Without opening the menu, you can activate
the command using the keystroke(s) shown.
Grayed command − The command is disabled. You cannot select the
command at this time. If a command is grayed, your equipment may not be
integrated correctly. For example, if the Use Sat Time command is grayed
under the Event Log menu, either you do not have access to satellite time,
or it is not integrated correctly.
To activate a command, first open the menu in which it is found, then
select the command. You can activate commands using either the trackball
or the key board.
