Using Your VAIO Computer
❑
The 2.4 GHz band, with which Bluetooth devices or wireless LAN devices work, is used by various devices. Bluetooth
devices use the technology to minimize the interference from other devices that use the same wave length. Simultaneous
use of the Bluetooth functionality and wireless communication devices, however, may cause radio interference and result
in poorer communication speeds and distances than the standard values.
❑
The Bluetooth functionality may not work depending on the third party devices or the software version used by third party
companies.
❑
As general characteristics of Bluetooth technology, connecting multiple Bluetooth devices to your computer may cause
bandwidth congestion, resulting in poor performance of the devices.
Bluetooth Security
The Bluetooth wireless technology has an authentication function, which allows you to determine with whom you choose to
communicate. With the authentication function, you can avoid any anonymous Bluetooth device to access your computer.
The first time two Bluetooth devices communicate, a common passkey (a password required for authentication) should be
determined for both devices to be registered. Once a device is registered, there is no need to re-enter the passkey.
✍
The passkey can be different each time, but must be the same at both ends.
For certain devices, such as a mouse, no passkey can be entered.
