operation is occurring outside of the allowable frequencies as 
listed above, the user must cease operating the Wireless LAN 
at that location and consult the local technical support staff 
responsible for the wireless network.
❖The 5 GHz Turbo mode feature is not allowed for operation in 
any European Community country.
❖This device must not be operated in ad-hoc mode using 
channels in the 5 GHz bands in the European Community. Ad-
hoc mode provides a direct communication between two client 
devices without a Wireless LAN Access Point.
❖This device must be used with Access Points that have 
employed and activated a radar detection feature required for 
European Community operation in the 5 GHz bands. This 
device will operate under the control of the Access Point in 
order to avoid operating on a channel occupied by any radar 
system in the area. The presence of nearby radar operation 
may result in temporary interruption of operation of this device. 
The Access Point’s radar detection feature will automatically 
restart operation on a channel free of radar. You may consult 
with the local technical support staff responsible for the 
wireless network to ensure the Access Point device(s) are 
properly configured for European Community operation.
