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 of the following measures: z Reorient or relocate the receiving antenna. z Increase the separation between the equipment and receiver. z Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. z Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. If this device is going to be operated in 5.15~ 5.25 GHz frequency range, then it is restricted in indoor environment only. Only 2412-2462MHz and 5180-5240MHz & 5745~5825MHz are available when placing to USA, other channels will be disabled. IMPORTANT NOTE: FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. - 3 - This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end user. - 4 - Europe – EU Declaration of Conformity This device complies with the essential requirements of the R&TTE Directive 1999/5/EC.
