In addition, while most of the information in the manual is correct for all countries, certain information 
is specific to the North American market and so may not be applicable to European users.  

Differences include the U.S standard external power supply details where some information (for 
example the AC transformer input voltage) will not be applicable for British/European use. 

Please 

note, however, that when a power supply adapter is ordered it will be suitable for use in your country. 

Reference to some radio transmitters, digital cell phones and aerials may also not be applicable 
according to your locality. 

Some brackets, shields and enclosure options, including wiring, are not sold as standard items in the 
European market; in some cases alternatives are offered. Details of the alternatives will be covered in 
separate manuals. 

Part numbers prefixed with a “#” symbol are special order parts for use with non-EU variants or for 
special installations. Please quote the full part number with the # when ordering.
