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.
Communication speed and distances can be inferior to the standard values. Interference from other devices may also stop
communications. Do not simultaneously use the Bluetooth functionality and wireless communication devices which use
the 2.4 GHz band, such as a wireless LAN PC Card.
❑
The Bluetooth functionality may not work depending on the third party devices or the software version used by third party
companies.
Bluetooth Security
The Bluetooth wireless technology has an authentication function, which allows you to determine 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.
