Press the [1] key while the EBL Maneuver Setting menu is open.
The EBL maneuver function will be set to on or off.
A auxiliary line for maneuver curve creation, a maneuver curve, and a WOL will
appear on the radar display.
Put the cursor on the starting point of the auxiliary line, and set the
bearing of the auxiliary line by operating the [EBL] dial.
The bearing of the auxiliary line is the final bearing in which the own ship is to move.
The WOL position varies depending on the bearing of the auxiliary line.
If the WOL is behind the own ship's position, the line color of WOL will change.
Press the [ENT] key.
The setting will be determined. However, if the WOL is behind the own ship's
position at this point, pressing of the [ENT] key is rejected, and the setting is not
determined.
