TO SET THE MAGNETIC DEClINATION ANGlE:
Magnetic declination is the angle between magnetic north (the direction the north end of a
compass needle points) and true north. The declination is positive when the magnetic north is
east of true north and negative when the magnetic north is west of true north. To find your exact
declination angle go to: www.ngdc.noaa.gov/geomagmodels/Declination.jsp.
NOTE: Incorrect magnetic declination will result in inaccurate compass readings.
1. From the main menu, select SETTINGS > GENERAl > MAG DEC ANGlE.
2. Press the up or down arrows on the Menu Selection Pad to select the amount of declination.
Magnetic declination ranges from -70 to 70. The default is 0.
3. Press the right arrow when finished.
4. Press BACK to return to the main menu.
