How to Handle This Device The WLAN device is an optional device that may come pre-installed in your mobile computer. Under normal circumstances, it should not be necessary for you to remove or re-install it. The operating system that your mobile computer comes with has been pre-configured to support the WLAN device. • The Wireless LAN devices support IEEE802.11b and IEEE802.11g. • The WLAN devices operate in the 2.4 GHz ISM band. • Microwave ovens may interfere with the operation of WLAN devices since they operate in the same 2.4 GHz frequency range as IEEE802.11 b/g devices. • Wireless devices that transmit in the 2.4 GHz range may interfere with operation of WLAN devices in IEEE802.11 b/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 Deactivating 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.). The WLAN device can be deactivated in Windows using the WLAN On/Off key (Fn + F5). Note that disconnecting via the icon in the system tray does not turn off the radio; it continues to transmit and receive even though it's not connected. BEFORE USING THE WIRELESS LAN DEVICE, YOU MUST FIRST INSTALL CLICKME! TO ENSURE THAT THE CORRECT SOFTWARE FOR YOUR DEVICE IS INSTALLED. SEE "INSTALLING CLICKME!" ON PAGE 73.

Before Using the Optional Wireless LAN
How to Handle This Device
The WLAN device is an optional device that may come pre-installed in your mobile computer. Under
normal circumstances, it should not be necessary for you to remove or re-install it. The operating system
that your mobile computer comes with has been pre-configured to support the WLAN device.
•
The Wireless LAN devices support IEEE802.11b and IEEE802.11g.
•
The WLAN devices operate in the 2.4 GHz ISM band.
•
Microwave ovens may interfere with the operation of WLAN devices since they operate in the same 2.4 GHz
frequency range as IEEE802.11 b/g devices.
•
Wireless devices that transmit in the 2.4 GHz range may interfere with operation of WLAN devices in
IEEE802.11 b/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 may be desired in certain circumstances (to extend battery life) or where
certain environments require it (i.e. hospitals, clinics, airplanes, etc.). The WLAN device can be
deactivated in Windows using the WLAN On/Off key (Fn + F5). Note that disconnecting via the icon in
