Appendix F

Wireless communication is often subject to local radio regulations. Although Wireless LAN networking products have been designed for operation in the license- free 2.4 GHz band, local radio regulations may impose limitations on the use of Wireless communication equipment.

NOTE: Refer to the flyer Information to the User for regulatory information that may apply in your country/region.

The range of the Wireless signal is related to the Transmit Rate of the Wireless communication. Communications at lower Transmit range may travel longer distances.

NOTE: The range values listed in Table F-5 are typical distances as measured at the Toshiba Wireless LAN laboratories. These values provide rule-of-thumb guides. They may vary according to the actual radio conditions at the location where the Wireless LAN product is installed.

❑The range of your Wireless devices can be affected when the antennas are placed near metal surfaces and solid high-density materials.

❑Range is also affected by obstacles in the signal path of the radio that may either absorb or reflect the radio signal.
