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 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 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. -Consult the dealer or an experienced radio/TV technician for help. MPE Reminding To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. Region Selection Limited by local law regulations, version for North America does not have region selection option. Information for the OEM Integrators This device is intended for OEM integrators only. Please see the full grant of equipment document for restrictions. Label Information to the End User by the OEM or Integrators If the FCC ID of this module is not visible when it is installed inside another device, then the outside of the device into which the module is into which the module is installed must be label with "Contains FCC ID: SU3RMWIFI".
