You need to calibrate the built-in digital compass when the app does not show the direction
correctly. See Notes on Built-In Sensors for more information.
Notes on Built-In Sensors
Before using built-in sensors, read the following precautions for correct use.
Notes on using the built-in accelerometer
You cannot change the computer screen orientation while your VAIO computer is connected
to an external display. If you connect the computer to an external display while using the
computer in portrait orientation, the computer screen will automatically change to landscape
(horizontal) orientation.
The computer screen may become distorted if you change the computer screen orientation
while the screen saver is activated.
Some apps do not support portrait orientation and may not work correctly. In this case, use
your VAIO computer in landscape orientation.
Notes on using the built-in digital compass
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.
The accuracy of the digital compass can be easily affected by magnetic interference and may
not work properly, particularly in the following locations:
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 a concourse of an airport or train station
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
The supplied pen (Digitizer Stylus) contains a magnet. If you bring the pen close to the magnetometer (
) on your VAIO computer or put it on the keyboard near the magnetometer, the digital compass
may not work properly. (Digitizer Stylus supplied models)
