Operating Basics
Bluetooth wireless technology
Bluetooth™ wireless technology eliminates the need for cables between
electronic devices such as desktop computers, printers and mobile phones.
You cannot use the built-in Bluetooth functions and an optional Bluetooth
SD card 2 simultaneously.
Bluetooth wireless technology has the following features:
Worldwide operation
The Bluetooth radio transmitter and receiver operate in the 2.4 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
maintained 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 to the right to turn it on and to the left to turn it off.
Set the switch to off in airplanes and hospitals. Check the indicator. It will
stop glowing when the wireless communication function is off.
