The system has basically been shown to comply with the limits for emitted spurious radiation for a
Class B digital device1, pursuant to Part 15 of the FCC Rules in the USA as well as comparable
regulations in other countries. This equipment generates uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to other equipment, 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 equipment and ODU.
• Connect the equipment 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 400 Series 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. Footnotes to the table below indicate countries
where registration of the link is currently mandatory.
