Calibrating compass indication
About compass indication
This watch measures earth magnetism directly with the built-in magnetic sensor
for compass indication.
Earth magnetism measurement is apt to be easily affected by environmental
conditions near a magnet or thing emitting strong electromagnetic waves.
In addition, generally, the north which a compass points to (magnetic north)
is different from that on a map (true north). You can determine the true north
through the compass function by calibration and adjustment of the watch.
You can use 2 methods to calibrate the compass of this watch: 2 point correction
(page 34) and declination correction (page 40).
Take care not to try to find compass direction around things generating strong
magnetic fields same as using an ordinary compass.
Avoid such an environment also while calibrating the compass.
