 determines if the profile is valid for the country of operation. The profile country must 

match the country in the options page or it must match the acquired country if 802.11d is 
enabled.

Single Country Use:
When the device is only used in a single country, set every profile country to 

. 

In the 

 dialog box (see 

), select the specific 

country the device is used in, and deselect the 

 option. This is the most common 

and efficient configuration, eliminating the initialization overhead associated with acquiring a 
country via 802.11d.

Multiple Country Use:
When the device is used in more than one country, select the 

 option in the 

 dialog box (see 

). This eliminates the need for 

reprogramming the country (in 

) each time you enter a new country. 

However, this only works if the infrastructure (i.e., APs) supports 802.11d (some 
infrastructures do not support 802.11d, including some Cisco APs). When the Enable 802.11d 
option is selected, the 

 > 

 setting is not used. For a single profile 

that can be used in multiple countries, with infrastructure that supports 802.11d (including 
Symbol infrastructure), set the Profile Country to

(Continued)

For a single profile that can be used in multiple countries, but with infrastructure that does not 
support 802.11d, set the profile country to 

, and de-select (uncheck) 

. In this case, the 

 setting must always be set to the 

country the device is currently in. This configuration option is the most efficient and may be 
chosen for use with any infrastructure. However, the 

 setting 

must be manually changed when a new country is entered.
Note that using a single profile in multiple countries implies that there is a common ESSID to 
connect to in each country. This is less likely than having unique ESSIDs in each country, this 
requires unique profiles for each country.

For additional efficiency when using multiple profiles that can be used in multiple countries, 
the country setting for each profile can be set to a specific country. If the current country (found 
via 802.11d or set by 

 when 802.11d is disabled) does not 

match the country set in a given profile, then that profile is disabled. This can make profile 
roaming occur faster. For example, if two profiles are created and configured for Japan, and 
two more profiles are created and configured for USA, then when in Japan only the first two 
profiles are active, and when in USA only the last two are active. If they had all been configured 
for 

, then all four would always be active, making profile roaming less 

efficient.
