7.2.1 Setting declination value

en

Declination is the angle between the true and magnetic North, and this function allows you to correct that difference. An interesting fact about declination is that the location of the magnetic North changes slightly every year. You can find the declination value from a map. For the most up-to-date value, do a search from the Internet (the National Geophysical Data Center in the United States supplies very accurate information).

You can set the declination value in MENU. To enter MENU, press [Mode] for 2 seconds - the menu icon in the upper right corner will blink twice.

In MENU, press [Down Light] to reach and [Mode] to enter COMPASS. You can set the declination to off or choose between East (E) or West (W) by pressing [Up] or [Down Light] and then [Mode]. Then set the declination value of your current location by pressing [Up] or [Down Light].
