Module No. 3515

Setting Up for True North Readings (Magnetic Declination Calibration)

If you want the watch to indicate true north instead of magnetic north, you need to specify your current location’s magnetic declination direction (east or west) and declination angle.

Magnetic North and True North

The magnetic declination angle value can be set in 1° (degree) units only. Use a value that is closest to the angle you want to set.
Example: For an angle of 7.4°, set 7°.
Example: For an angle of 7°40’ (7 degrees, 40 minutes), set 8°.

Note

Magnetic declination angles (east or west) and angle degree values for specific locations can be found on geographic maps, mountain climbing maps, and other maps that include contour lines.
