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 function and wireless communication devices, however, may cause radio interference and result in
reduced communication speeds and distances than the standard values.
✍
Read the Bluetooth regulations guide before using the Bluetooth function.
❑
The Bluetooth function may not work with other devices, depending on the manufacturer or the software version employed
by the manufacturer.
❑
Connecting multiple Bluetooth devices to your computer may cause bandwidth congestion, resulting in poor performance
of the devices. This is normal with Bluetooth technology and is not a malfunction.
