SeaClear II Help

How do I change from True North to Magnetic North in this software?
I want to plan my routes by Magnetic North instead of True North.

I have figured out the basics of the software so far.

from the manual

SeaClear automatically calculates the magnetic variation for the current position. Calculation is
based on the most current data available to achieve best result. To disable internal calculation and
use values from the GPS, see the SeaClear_2.INI File Setting section.
