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: -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. “Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the 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.” “In order to comply with FCC RF Exposure requirements, this device must be installed to provide at least 0.5 cm separation from the human body at all times.

Maximum Permissible Exposure RF Exposure Limit According to KDB 447498D01 v06: The 1g and 10g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ꞏ[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is <5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Device category : Portable device Transmitting mode : Single transmitting Max. transmitting frequency : 2 480 MHz Min. test separation distance : 5 mm Max. Antenna Gain : 1.0 dBi Max. Average power : -2.95 dBm Max. power with turn-up tolerance : -1.00 dBm 0.79 mW For this device: 0.79 mW[maximum average output power]/5 mm[minimum separation distance] x √2.48 GHz = 0.25 Note. The calculation result was rounded to one decimal place for comparison. Test Result : This is less than 3.0 for 1-g SAR. SAR evaluation for general population exposure conditions by measurement or numerical simulation is not required. END REPORT
