The system has been tested for compliance to both US (FCC) and European (ETSI) specifications. It 
has been shown to comply with the limits for emitted spurious radiation for a Class B digital device
1
, 
pursuant to Part 15 of the FCC Rules in the USA and appropriate European ENs. These limits have 
been designed to provide reasonable 
protection against harmful interference. However the equipment 
can radiate radio frequency energy and, if not installed and used in accordance with the instructions, 
may cause harmful interference to other radio communications. There is no guarantee that 
interference will not occur in a particular installation. 
If this equipment does cause harmful interference to radio or television reception, which can be 
determined by turning the equipment off and on, the user is encouraged to try to correct the 
interference by one or more of the following measures:  
•  Reorient or relocate the Outdoor Unit (ODU).  
•  Increase the separation between the affected equipment and ODU.  
•  Connect the ODU/PIDU into a power outlet on a circuit different from that to which the 
receiver is connected.  
•  Consult your installer or supplier for help. 
Deployment and Operation 
The Radio Regulations of various countries’ limits constrain the operation of radio products generally. 
In particular the local regulator may limit the amount of conducted or radiated transmitter power and 
may require registration of the radio link. 
The power transmitted by the PTP 500 Series Bridge is controlled by the use of Region-specific 
License Keys. 
The following examples show how the regulatory limits apply in some specific countries at the current 
time. Operators should note that regulations are subject to change. 
Contact your supplier/installer to ensure that your product is set for the correct License Key for your 
Country/Region and to ensure that you have fulfilled all the local regulatory requirements, especially if 
you are intending to use a link with external antennas. Notes below the tables indicate countries 
where registration of the link is currently mandatory.
