Operating Basics

Security

Be sure to enable WEP/WPA (encryption) function. Otherwise your

computer will allow the illegal access by outsider through Wireless LAN

to cause illegal intrusion, eavesdropping, and loss or destruction of

stored data. TOSHIBA strongly recommend the customer to enable the

WEP/WPA function.

TOSHIBA is not liable for the eavesdropping of data due to the use of

Wireless LAN and the damage thereof.

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 3 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.

The numerical values for display are the theoretical maximums for

Wireless LAN standards. The actual values may differ.

The transmission speed over the wireless LAN and the distance over

which wireless LAN can reach may vary depending on surrounding

electromagnetic environment, obstacles, access point design and

configuration, and client design and software/hardware configurations.

The Transmit Rate (at X Mbit/s) is the theoretical maximum speed

under the IEEE802.11 (b/g) standard. The actual transmission speed

will be lower than the theoretical maximum speed.
To use the Atheros Super G

TM

function, your client and access point

must support the corresponding feature. Performance of these

functions may vary depending on the format of data transmitted.
