To lock the direction
You can use Compass to lock the indicated direction to help you
maintain a specific bearing while trekking, etc. While the watch's
12 o'clock position is pointed in the direction you want, tap the touch
screen.
To unlock a direction, tap the touch screen again.
Magnetization Correction
When the message "Perform magnetization correction." appears on
the compass screen, it means that you need to perform magnetization
correction of the watch. Move your arm so the watch faces front, back,
left, and right. An animated message will appear on the watch display
to give you an idea of how you need to move the watch. Keep moving
your arm until the message disappears, indicating that magnetization
correction is complete.
Note: The watch normally performs magnetization correction
automatically. You only need to perform the above operation
when the message appears.
Magnetic North and True North
North indicated by this watch under initial default settings is magnetic
north. If you want the watch to indicate true north, you need to use an
Android smartphone to configure required settings. See
and TOOL App
