Operation is subject to the following 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. NOTES: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. ANY CHARGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE GRANTEE OF THIS DEVICE COULD VOID THE USER’S AUTHORITY TO OPERATE THE DEVICE. NOTE: 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 corrected. -- Consult the dealer or experienced radio / TV technician for help. IC: 7666A-BKM4AB -English: This device complies with Industry Canada RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference,including interference that may cause undesired operation of the device. French: Leprésent appareil est conforme aux CNR d'Industrie Canada applicable aux appareils radio Exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, meme si le brouillage est susceptible d'en compromettre le fonctionnement." NOTES: (i) This device shall be installed and operated in a completely enclosed container to prevent RF emissions, which otherwise can interfere with aeronautical navigation. Installation shall be done by trained installers, in strict compliance with the manufacturer’s instructions. (ii) The use of this device is on a “no-interference, no-protection” basis. That is, the user shall accept operations of high-powered radar in the same frequency band which may interfere with or damage this device. However, level probing devices found to interfere with primary licensing operations will be required to be removed at the user’s expense. (iii) The RF explosure compliance distance: 20mm

Date: 2015-09-15 Report Number: 60.790.15.008.01 Model No.: BKM4AB Radiofrequency radiation exposure evaluation According to KDB 447498 D01v05r02 section 4.3.1, >> The 1-g SAR test exclusion thresholds for 100MHz to 6GHz, at test separation distances ” 50 mm are determined by: Power at 2457GHz = 0.8531 mW EIRP Power at 2402GHz = 1.1912 mW EIRP Power at 2440GHz = 1.1721 mW EIRP Power at 2480GHz = 1.3335 mW EIRP [(0.8531 mW) / (50 mm)] · [sqrt (2457 GHz)] = 0.8457 which is ” 3.0 for 1-g SAR. [(1.1912 mW) / (50 mm)] · [sqrt (2402 GHz)] = 1.1676 which is ” 3.0 for 1-g SAR. [(1.1721 mW) / (50 mm)] · [sqrt (2440 GHz)] = 1.1579 which is ” 3.0 for 1-g SAR. [(1.1335 mW) / (50 mm)] · [sqrt (2480 GHz)] = 1.1289 which is ” 3.0 for 1-g SAR. Therefore the device is exempt from stand-alone SAR test requirements. >> The fundamental frequency of the EUT is 2457MHz, the test separation distance is < 50mm. >> The power of EUT measured is: - For 2457MHz: 0.8531mW = 10 log (0.8531) dBm ~ -0.69dBm - For 2402MHz: 1.1912mW = 10 log (1.1912) dBm ~ +0.76dBm - For 2440MHz: 1.1721mW = 10 log (1.1721) dBm ~ -+0.69dBm - For 2480MHz: 1.3335mW = 10 log (1.3335) dBm ~ +1.25dBm Page 1 of 1 TÜV SÜD Hong Kong Ltd. 3/F, West Wing, Phase 2, 10 Science Park West Avenue, Hong Kong Science Park, Shatin, Hong Kong
