◆ Precautions for using electronic
compass
An electronic compass is equipped with the terminal and it
senses the faint fluctuation in the magnetic field of the earth to
calculate directions.
･
The electronic compass calculates directions by sensing the
faint fluctuation in the magnetic field of the earth. Therefore,
the magnetic field may not be sensed or a direction may not
be displayed correctly when the terminal is used inside or
near buildings (including underground shopping area),
vehicles, metal facilities (an elevator etc.), metal equipment
(a guardrail, pedestrian bridge, etc.), high-tension wires,
wires, rocks containing magnetism, metal (metal desk,
locker, etc.), permanent magnet (a magnetic necklace, bag
fastening, etc.), home appliances (a TV, computer, speaker,
etc.).
･
When an applications such as "Maps" cannot calculate
directions correctly, adjust the electronic compass.
◆ Adjusting the electronic compass
■ Operation method
While using an application such as "Maps" that uses the
electronic compass, move the terminal like describing a big
figure of eight, twisting your wrist for around 10 seconds.
