Sony VAIO Duo 13 User Manual page 131

When magnetism around your VAIO computer is unstable, the accuracy of the built-in digital
compass may decrease; however, this is normal and does not indicate a malfunction. In such
a case, you need to calibrate the digital compass.
Move away from materials that cause magnetic interference, such as metallic products or
magnets, and perform the following operations while running an app that uses the digital
compass.
On the pen supplied models, perform the operations while keeping the pen away from your
VAIO computer.
Place your VAIO computer on a flat surface, hold the computer with both hands, then rotate it 360
degrees clockwise with the LCD screen up.
Normally rotate your VAIO computer about 5 to 10 times. In a location subject to strong magnetic
interference, rotate the computer about 10 to 20 times.
If the problem persists, use your VAIO computer in a location with less magnetic interference.
