Note: The OEM is free to choose another vendor’s antenna of like type and equal or lesser gain as an antenna appearing
in the table and still maintain compliance. Reference FCC Part 15.204(c)(4) for further information on this topic.
To reduce potential radio interference to other users, the antenna type and gain should be chosen so that the
equivalent isotropic radiated power (EIRP) is not more than that permitted for successful communication.
4.2 FCC Documentation Requirements
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. 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 an 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 of the following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
