Bluetooth wireless technology
Bluetooth™ wireless technology eliminates the need for cables between elec-
tronic devices such as desktop computers, printers and mobile phones. You can-
not use the built-in Bluetooth functions and an optional Bluetooth PC card
simultaneously.
Bluetooth wireless technology has the following features:
Worldwide operation
The Bluetooth radio transmitter and receiver operates in the 2.45 GHz band, which
is license-free and compatible with radio systems in most countries in the world.
Radio links
You can easily establish links between two or more devices. The link is main-
tained even if the devices are not within line of sight.
Security
Two advanced security mechanisms ensure a high level of security:
◆Authentication prevents access to critical data and makes it impossible to
falsify the origin of a message.
◆Encryption prevents eavesdropping and maintains link privacy.
Wireless communication switch
You can enable or disable Wireless LAN and Bluetooth functions, with the on/off
switch. No transmissions are sent or received when the switch is off. Slide the
switch toward the left of the computer to turn it on and toward the right of the
computer to turn it off.
CAUTION: Set the switch to off in airplanes and hospitals. Check the
indicator. It will stop glowing when the wireless communication function
is off.
Turn the computer off when you enter an airplane and check the carrier’s regula-
tions before you use a computer on board.
