FCC Warnning: 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 againstharmful interference in a residential installation. This equipment generates, uses and can radiateradio frequency energy and, if not installed and used in accordance with the instructions, maycause harmful interference to radio communications. However, there is no guarantee thatinterference will not occur in a particular installation. If this equipment does cause harmfulinterference to radio or television reception, which can be determined by turning the equipmentoff and on, the user is encouraged to try to correct the interference by one or more of thefollowing 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. Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your 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. 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 and your body.

RF Exposure evaluation FCC ID: 2A87Y-B24 Exposure category: General population/uncontrolled environment EUT Type: Production Unit Device Type: Mobile Device 1. Reference According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. KDB447498 D01: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 2.

MPE Calculation Method Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 4. Antenna Information B24wwrgb can only use antennas certificated as follows provided by manufacturer; Antenna No. Model No. of antenna: Type of antenna: Gain of the antenna (Max.) Frequency range: BT / PCB Antenna -1.00dBi for 2400-2500MHz; 5. Manufacturing Tolerance BLE GFSK(Peak) Channel Channel 00 Channel 19 Channel 39 Target (dBm) 1.0 0.0 0.0 Tolerance ±(dB) 1.0 1.0 1.0 6. Standalone MPE Result As declared by the Applicant, the EUT is a wireless device used in a fix application, at least 20 cm from any body part of the user or nearby persons; from the maximum EUT RF output power, the minimum separation distance, r =20cm, as well as the gain of the used antenna is 1.0dBi, the RF power density can be obtained. Modulation Type Output power Antenna Gain (dBi) Antenna Gain (linear) MPE (mW/cm 2 ) MPE Limits (mW/cm 2 ) dBm mW BLE 2.0 1.5849 -1.0 0.7943 0.0003 1.0000 Remark: 1.
