I can’t figure out how to set the declination angle.
To find your exact declination angle, go to www.ngdc.noaa.gov/geomagmodels/Declination.jsp. Setting an incorrect magnetic declination will result in inaccurate compass readings, so make sure to you have the correct angle. Then, go to the main menu screen on your Handheld Device and select SETTINGS>GENERAL>MAG DEC ANGLE. Press the up or down arrow on the Menu Selection Pad to select the amount of declination. Magnetic declination ranges from -70 to 70. The default is 0. Press the right arrow when finished. You magnetic declination is now set. Press BACK to return to the main menu.
