Set Rate of Turn
(Not applicable for analog drives)
The setting determines both the Rate of turn and the Turn gain
(ref. Settings Menu, page 155) used for course changes in
automatic steering modes. It is essential that this setting is
carried out at sea when the boat is turning. To avoid setting at
dockside it is blocked for rate of turn less than 5°/min.
Before this setting, the display shows ‘Not done’ with default
rate of turn to the left. Afterwards the display reads ‘Done’ with
set value to the left. The present rate of turn is always shown to
the right.
