The built-in digital compass works by detecting a magnetic direction. Do not rely solely on the location information the built-in digital compass provides.

Especially at the following locations, the accuracy of the digital compass can be easily affected by magnetic interference and it may not work correctly.

• Inside an elevator or a room built with ferrous materials, such as iron frames or reinforced concrete

• Near a reinforced concrete structure, such as a footbridge or an airport or a train station concourse

• Near or inside a train or a car

• Near a transformer on the ground or high-voltage power lines

• Near a metallic product, such as a metal frame desk or metallic furniture

• Near a material that has a high level of magnetic interference, such as a magnet, a magnetic holder, or speakers

Calibrating the built-in digital compass may correct the direction. See Notes on Built-In Sensors for more information.
