- Before Using the Optional Wireless LAN
• Microwave ovens may interfere with the operation of WLAN devices since they operate in the same 2.4 GHz frequency
range as IEEE802.11b/g/n devices. Interference by microwaves does not occur with IEEE802.11a radio which operates
in the 5 GHz RF band.
• Wireless devices that transmit in the 2.4 GHz range may interfere with operation of WLAN devices in IEEE802.11b/g/n
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/Disconnecting the WLAN Device
Disconnecting 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 by using the Wireless On/Off Switch, and it can be disconnected in Windows using the WLAN
icon in the system tray (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. BEFORE INSTALLING CLICKME!, BE SURE
THE WLAN SWITCH IS IN THE ON POSITION. SEE “INSTALLING CLICKME!” ON PAGE 57.
Deactivation Using the
Wireless On/Off Switch
The WLAN device can be deactivated
quickly and efficiently by toggling the
Wireless On/Off Switch to the Off
position. The Wireless On/Off switch has
no effect on non-Wireless LAN models.
