Why doesn't the digital compass on my desktop display the correct direction?
❑ The digital compass on the desktop displays the direction in which you are currently facing by detecting ambient
geomagnetism. Because geomagnetism is affected by ambient environment, the digital compass may not display the
correct direction at the following locations:
❑ Inside an elevator or a room surrounded by ferroconcrete or steel-frame walls
❑ Locations surrounded by ferroconcrete structures, such as a footbridge or a concourse
❑ Locations near or inside a train or a car
❑ Locations near a transformer on the ground or high-voltage power lines
❑ Locations near metallic products, such as a metallic desk or metallic furniture
❑ Locations near magnets or magnetized products, such as speakers
❑ The direction may be displayed correctly by calibrating the built-in digital compass. To calibrate the digital compass, follow
these steps:
1 Click Start, All Programs, and VAIO Control Center.
2 Click Location Info/GPS and Adjust Digital Compass.
3 Follow the on-screen instructions.
