current location from a map, the website of the Geospatial Information Authority of
Japan, or other sources, and enter the value following the procedure below.
① Press and hold Button Ⓓ while the direction measurement is in progress or stopped
to show the magnetic declination correction display. "DECLIn" appears in the top
