How to Use
Notes on Built-In Sensors
Before using built-in sensors, read the following precautions for correct use.
Notes on using the built-in accelerometer
If you change the computer screen orientation without closing running apps, such as a
video playback app, all unsaved data may be lost.
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
Adjusting the angle of the LCD screen may reduce the accuracy of the built-in digital
compass; 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.
Place your VAIO computer on a flat surface, hold the computer with both hands, then
rotate it 360 degrees clockwise once with the LCD screen up.
Place your VAIO computer on a flat surface, hold the computer with both hands, then
rotate it 360 degrees lengthwise once.
