Note:
A magnetic variation value set with AUTO is a rough value calculated
based on the current date and time, and the ship's current position.
You cannot set it with AUTO if the data of the current date & time
and the current ship's position is not stored.
When it is necessary to set a more precise value or when the
abovementioned data is not stored, set it with MANUAL.
