■
The WLAN device operates in the 2.4GHz ISM band
and the 5 GHz lower, middle, and upper UNII bands.
■
Microwave ovens may interfere with the operation of
WLAN devices since they operate in the same 2.4GHz
frequency range as IEEE802.11b/g devices. Interfer-
ence by microwaves does not occur with IEEE802.11a
radio which operates in the 5 GHz RF band.
■
Wireless devices that transmit in the 2.4GHz range
may interfere with operation of WLAN devices in
IEEE802.11b/g modes. Symptoms of interference
include reduced throughput, intermittent disconnects,
and many frame errors. It is HIGHLY recommended
that these interfering devices be powered off to ensure
proper operation of the WLAN device.
DEACTIVATING THE WLAN DEVICE
Deactivation of the WLAN device may be desired in
certain circumstances (to extend battery life) or where
certain environments require it (i.e. hospitals, clinics,
airplanes, etc.). Fujitsu mobile computers employ two
methods with which to deactivate the WLAN device:
■
Using the Wireless On/Off Switch, or,
■
In Windows, using the WLAN icon in the taskbar.
Deactivation using the Wireless On/Off Switch
The WLAN device can be deactivated quickly and effi-
ciently by sliding the Wireless On/Off Switch to the Off
position (to the left).
(Figure A-3)
The wireless On/Off switch has no effect on non-Wire-
less LAN models.

Deactivation using the icon in the taskbar
1.
Right-click the WLAN icon in the taskbar at the
bottom right of your screen.
2.
Choose Disconnect from a network.
ACTIVATING THE WLAN DEVICE
Activation of the WLAN device can be accomplished
using the same methods as the deactivation process
■
Using the Wireless On/Off Switch
■
In Windows, by right-clicking the WLAN icon then
clicking “Connect to a network”
