13www.ibroadlink.com 8.2 Minimizing Radio Interference The following precautions should be considered during designing when using PCB antenna: 1. Do not place any electrical components in antenna area on main board and it’s better to leave this area blank on PCB. 2. It is recommended to not place any electrical components within 10mm range of module antenna and not design any circuit or bond copper on main board under this area. 3. Do not use the module inside any metal case or containers with metal painting. Keep the antenna of wifi module next to the edge of main board during design of PCB to ensure better performance of antenna.

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 Requirements To satisfy FCC / IC 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. Les antennes installées doivent être situées de facon à ce que la population ne puisse y être exposée à une distance de moin de 20 cm. Installer les antennes de facon à ce que le personnel ne puisse approcher à 20 cm ou moins de la position centrale de l’ antenne. La FCC des éltats-unis stipule que cet appareil doit être en tout temps éloigné d’au moins 20 cm des personnes pendant son functionnement.
